Assignment operators are used in programming to  assign values  to variables. We use an assignment operator to store and update data within a program. They enable programmers to store data in variables and manipulate that data. The most common assignment operator is the equals sign ( = ), which assigns the value on the right side of the operator to the variable on the left side.

Types of Assignment Operators:

• Simple Assignment Operator ( = )
• Addition Assignment Operator ( += )
• Subtraction Assignment Operator ( -= )
• Multiplication Assignment Operator ( *= )
• Division Assignment Operator ( /= )
• Modulus Assignment Operator ( %= )

Assignment Operators in C

In C, the assignment operator stores a certain value in an already declared variable. A variable in C can be assigned the value in the form of a literal, another variable or an expression. The value to be assigned forms the right hand operand, whereas the variable to be assigned should be the operand to the left of = symbol, which is defined as a simple assignment operator in C. In addition, C has several augmented assignment operators.

The following table lists the assignment operators supported by the C language −

Simple assignment operator (=)

The = operator is the most frequently used operator in C. As per ANSI C standard, all the variables must be declared in the beginning. Variable declaration after the first processing statement is not allowed. You can declare a variable to be assigned a value later in the code, or you can initialize it at the time of declaration.

You can use a literal, another variable or an expression in the assignment statement.

Once a variable of a certain type is declared, it cannot be assigned a value of any other type. In such a case the C compiler reports a type mismatch error.

In C, the expressions that refer to a memory location are called "lvalue" expressions. A lvalue may appear as either the left-hand or right-hand side of an assignment.

On the other hand, the term rvalue refers to a data value that is stored at some address in memory. A rvalue is an expression that cannot have a value assigned to it which means an rvalue may appear on the right-hand side but not on the left-hand side of an assignment.

Variables are lvalues and so they may appear on the left-hand side of an assignment. Numeric literals are rvalues and so they may not be assigned and cannot appear on the left-hand side. Take a look at the following valid and invalid statements −

Augmented assignment operators

In addition to the = operator, C allows you to combine arithmetic and bitwise operators with the = symbol to form augmented or compound assignment operator. The augmented operators offer a convenient shortcut for combining arithmetic or bitwise operation with assignment.

For example, the expression a+=b has the same effect of performing a+b first and then assigning the result back to the variable a.

Similarly, the expression a<<=b has the same effect of performing a<<b first and then assigning the result back to the variable a.

Here is a C program that demonstrates the use of assignment operators in C:

When you compile and execute the above program, it produces the following result −

C Assignment Operators

• 6 contributors

An assignment operation assigns the value of the right-hand operand to the storage location named by the left-hand operand. Therefore, the left-hand operand of an assignment operation must be a modifiable l-value. After the assignment, an assignment expression has the value of the left operand but isn't an l-value.

assignment-expression :   conditional-expression   unary-expression assignment-operator assignment-expression

assignment-operator : one of   = *= /= %= += -= <<= >>= &= ^= |=

The assignment operators in C can both transform and assign values in a single operation. C provides the following assignment operators:

In assignment, the type of the right-hand value is converted to the type of the left-hand value, and the value is stored in the left operand after the assignment has taken place. The left operand must not be an array, a function, or a constant. The specific conversion path, which depends on the two types, is outlined in detail in Type Conversions .

Assignment operators.

Assignment operators modify the value of the object.

[ edit ] Definitions

Copy assignment replaces the contents of the object a with a copy of the contents of b ( b is not modified). For class types, this is performed in a special member function, described in copy assignment operator .

For non-class types, copy and move assignment are indistinguishable and are referred to as direct assignment .

Compound assignment replace the contents of the object a with the result of a binary operation between the previous value of a and the value of b .

[ edit ] Assignment operator syntax

The assignment expressions have the form

• ↑ target-expr must have higher precedence than an assignment expression.
• ↑ new-value cannot be a comma expression, because its precedence is lower.

[ edit ] Built-in simple assignment operator

For the built-in simple assignment, the object referred to by target-expr is modified by replacing its value with the result of new-value . target-expr must be a modifiable lvalue.

The result of a built-in simple assignment is an lvalue of the type of target-expr , referring to target-expr . If target-expr is a bit-field , the result is also a bit-field.

[ edit ] Assignment from an expression

If new-value is an expression, it is implicitly converted to the cv-unqualified type of target-expr . When target-expr is a bit-field that cannot represent the value of the expression, the resulting value of the bit-field is implementation-defined.

If target-expr and new-value identify overlapping objects, the behavior is undefined (unless the overlap is exact and the type is the same).

In overload resolution against user-defined operators , for every type T , the following function signatures participate in overload resolution:

For every enumeration or pointer to member type T , optionally volatile-qualified, the following function signature participates in overload resolution:

For every pair A1 and A2 , where A1 is an arithmetic type (optionally volatile-qualified) and A2 is a promoted arithmetic type, the following function signature participates in overload resolution:

[ edit ] Built-in compound assignment operator

The behavior of every built-in compound-assignment expression target-expr   op   =   new-value is exactly the same as the behavior of the expression target-expr   =   target-expr   op   new-value , except that target-expr is evaluated only once.

The requirements on target-expr and new-value of built-in simple assignment operators also apply. Furthermore:

• For + = and - = , the type of target-expr must be an arithmetic type or a pointer to a (possibly cv-qualified) completely-defined object type .
• For all other compound assignment operators, the type of target-expr must be an arithmetic type.

In overload resolution against user-defined operators , for every pair A1 and A2 , where A1 is an arithmetic type (optionally volatile-qualified) and A2 is a promoted arithmetic type, the following function signatures participate in overload resolution:

For every pair I1 and I2 , where I1 is an integral type (optionally volatile-qualified) and I2 is a promoted integral type, the following function signatures participate in overload resolution:

For every optionally cv-qualified object type T , the following function signatures participate in overload resolution:

An assignment statement sets and/or re-sets the value stored in the storage location(s) denoted by a variable name; in other words, it copies a value into the variable. [1]

The assignment operator allows us to change the value of a modifiable data object (for beginning programmers this typically means a variable). It is associated with the concept of moving a value into the storage location (again usually a variable). Within most programming languages the symbol used for assignment is the equal symbol. But bite your tongue, when you see the = symbol you need to start thinking: assignment. The assignment operator has two operands. The one to the left of the operator is usually an identifier name for a variable. The one to the right of the operator is a value.

Simple Assignment

The value 21 is moved to the memory location for the variable named: age. Another way to say it: age is assigned the value 21.

Assignment with an Expression

The item to the right of the assignment operator is an expression. The expression will be evaluated and the answer is 14. The value 14 would be assigned to the variable named: total_cousins.

Assignment with Identifier Names in the Expression

The expression to the right of the assignment operator contains some identifier names. The program would fetch the values stored in those variables; add them together and get a value of 44; then assign the 44 to the total_students variable.

Welcome, bold programmers and coding enthusiasts! Let's set the stage: you're at your desk, fingers hovering over the keyboard, ready to embark on a journey deep into the belly of C programming. You might be wondering, why do I need to know about these 'assignment operators'?

Well, imagine trying to build a house with a toolbox that only has a hammer. You could probably make something that vaguely resembles a house, but without a screwdriver, wrench, or saw, it's going to be a bit...wobbly. This, my friends, is the importance of understanding operators in C. They're like the indispensable tools in your coding toolbox. And today, we're honing in on the assignment operators .

Now, our mission, should we choose to accept it, is to delve into the world of assignment operators in C. Like secret agents discovering the inner workings of a villain's lair, we're going to uncover the secrets that these '=' or '+=' symbols hold.

To all the night owls out there, I see you, and I raise you an operator. Just like how a cup of coffee (or three) helps us conquer that midnight oil, mastering operators in C can transform your coding journey from a groggy stumble to a smooth sprint.

But don't just take my word for it. Let's take a real-world example. Imagine you're coding a video game. You need your character to jump higher each time they collect a power-up. Without assignment operators, you'd be stuck adding numbers line by line. But with the '+=' operator, you can simply write 'jumpHeight += powerUpBoost,' and your code becomes a thing of elegance. It's like going from riding a tricycle to a high-speed motorbike.

In this article, we're going to unpack, examine, and get intimately acquainted with these assignment operators. We'll reveal their secrets, understand their behaviors, and learn how to use them effectively to power our C programming skills to new heights. Let's strap in, buckle up, and get ready for takeoff into the cosmic realms of C assignment operators!

The Basics Of C Operators

Deep dive into assignment operators in c, detailed exploration of each assignment operator, common use cases of assignment operators, common mistakes and how to avoid them, practice exercises, references and further reading.

Alright, get ready to pack your mental suitcase as we prepare to embark on the grand tour of C operators. We'll be stopping by the various categories, getting to know the locals (the operators, that is), and understanding how they contribute to the vibrant community that is a C program.

What Are Operators In C?

Operators in C are like the spicy condiments of coding. Without them, you'd be left with a bland dish—or rather, a simple list of variables. But splash on some operators, and suddenly you've got yourself an extravagant, dynamic, computational feast. In technical terms, operators are special symbols that perform specific operations on one, two, or three operands, and then return a result . They're the magic sauce that allows us to perform calculations, manipulate bits, and compare data.

Categories Of Operators In C

Now, just as you wouldn't use hot sauce on your ice cream (unless that's your thing), different operators serve different purposes. C language has been generous enough to provide us with a variety of operator categories, each with its distinct charm and role.

Let's break it down:

Imagine you're running a pizza shop. The arithmetic operators are like your basic ingredients: cheese, sauce, dough. They form the foundation of your pizza (program). But then you want to offer different pizza sizes. That's where your relational operators come in, comparing the diameter of small, medium, and large pizzas.

You're going well, but then you decide to offer deals. Buy two pizzas, get one free. Enter the logical operators , evaluating whether the conditions for the deal have been met. And finally, you want to spice things up with some exotic ingredients. That's your bitwise operators , working behind the scenes, adding that unique flavor that makes your customers keep coming back.

However, today, we're going to focus on a particular subset of the arithmetic operators: the assignment operators . These are the operators that don't just make the pizza but ensure it reaches the customer's plate (or in this case, the right variable).

Next up: We explore these unsung heroes of the programming world, toasting their accomplishments and discovering their capabilities. So, hold onto your hats and glasses, folks. This here's the wildest ride in the coding wilderness!

Prepare your diving gear and adjust your oxygen masks, friends, as we're about to plunge deep into the ocean of C programming. Hidden in the coral reef of code, you'll find the bright and beautiful creatures known as assignment operators.

What Are Assignment Operators?

In the broad ocean of C operators, the assignment operators are the dolphins - intelligent, adaptable, and extremely useful. On the surface, they may appear simple, but don't be fooled; these creatures are powerful. They have the capability to not only assign values to variables but also perform arithmetic operations concurrently.

The basic assignment operator in C is the '=' symbol. It's like the water of the ocean, essential to life (in the world of C programming). But alongside this staple, we have a whole family of compound assignment operators including '+=', '-=', '*=', '/=', and '%='. These are the playful dolphins leaping out of the water, each adding their unique twist to the task of assignment.

Syntax And Usage Of Assignment Operators

Remember, even dolphins have their ways of communicating, and so do assignment operators. They communicate through their syntax. The syntax for assignment operators in C follows a simple pattern:

In this dance, the operator and the '=' symbol perform a duet, holding onto each other without a space in between. They're the dancing pair that adds life to the party (aka your program).

Let's say you've won the lottery (congratulations, by the way!) and you want to divide your winnings between your three children. You could write out the arithmetic long-hand, or you could use the '/=' operator to streamline your process:

Just like that, your winnings are divided evenly, no calculator required.

List Of Assignment Operators In C

As promised, let's get to know the whole family of assignment operators residing in the C ocean:

Alright, we've taken the plunge and gotten our feet wet (or fins, in the case of our dolphin friends). But the dive is far from over. Next up, we're going to swim alongside each of these assignment operators, exploring their unique behaviors and abilities in the wild, vibrant world of C programming. So, keep your scuba gear on and get ready for more underwater adventure!

Welcome back, dear diver! Now that we've acquainted ourselves with the beautiful pod of dolphins, aka assignment operators, it's time to learn about each dolphin individually. We're about to uncover their quirks, appreciate their styles, and recognize their talents.

The Simple Assignment Operator '='

Let's start with the leader of the pack: the '=' operator. This unassuming symbol is like the diligent mail carrier, ensuring the right packages (values) get to the correct houses (variables).

Take a look at this:

In this code snippet, '=' ensures that the value '5' gets assigned to the variable 'chocolate'. Simple as that. No muss, no fuss, just a straightforward delivery of value.

The Addition Assignment Operator '+='

Next, we have the '+=' operator. This operator is a bit like a friendly baker. He takes what he has, adds more ingredients, and gives you the result - a delicious cake! Or, in this case, a new value.

Consider this:

We started with 12 doughnuts. But oh look, a friend dropped by with 3 more! So we add those to our box, and now we have 15. The '+=' operator made that addition quick and easy.

The Subtraction Assignment Operator '-='

Following the '+=' operator, we have its twin but with a different personality - the '-=' operator. If '+=' is the friendly baker, then '-=' is the weight-conscious friend who always removes extra toppings from their pizza. They take away rather than add.

For instance:

You've consumed 2000 calories today, but then you went for a run and burned 500. The '-=' operator is there to quickly update your calorie count.

The Multiplication Assignment Operator '*='

Say hello to the '*=' operator. This one is like the enthusiastic party planner who multiplies the fun! They take your initial value and multiply it with another, bringing more to the table.

Check this out:

You're at a level 7 excitement about your upcoming birthday, but then you learn that your best friend is flying in to celebrate with you. Your excitement level just doubled, and '*=' is here to make that calculation easy.

The Division Assignment Operator '/='

Here's the '/=' operator, the calm and composed yoga teacher of the group. They're all about division and balance. They take your original value and divide it by another, bringing harmony to your code.

You're pretty anxious about your job interview - let's say a level 10 anxiety. But then you do some deep breathing exercises, which helps you halve your anxiety level. The '/=' operator helps you reflect that change in your code.

The Modulus Assignment Operator '%='

Finally, we meet the quirky '%=' operator, the mystery novelist of the group. They're not about the whole story but the remainder, the leftovers, the little details others might overlook.

Look at this:

You have 10 books to distribute equally among your 3 friends. Everyone gets 3, and you're left with 1 book. The '%=' operator is there to quickly calculate that remainder for you.

That's the end of our detailed exploration. I hope this underwater journey has provided you with a greater appreciation and understanding of these remarkable creatures. Remember, each operator, like a dolphin, has its unique abilities, and knowing how to utilize them effectively can greatly enhance your programming prowess.

Now, let's swerve away from the theoretical and deep-dive into the practical. After all, C assignment operators aren't just sparkling little seashells you collect and admire. They're more like versatile tools in your programming Swiss Army knife. So, let's carve out some real-world use cases for our cherished assignment operators.

Variable Initialization And Value Change

Assignment operators aren't just for show; they've got some moves. Take our plain and humble '='. It's the bread-and-butter operator used in variable initialization and value changes, helping your code be as versatile as a chameleon.

In this scenario, our friend '=' is doing double duty—initializing 'a' with the value 10 and then changing it to 20. Not flashy, but oh-so-vital.

Calculation Updates In Real-Time Applications

Assignment operators are like those awesome, multitasking waitstaff you see in busy restaurants, juggling multiple tables and orders while still managing to serve everyone with a smile. They are brilliant when you want to perform real-time updates to your data.

In this scenario, '+=' and '-=' are the maitre d' of our code-restaurant, updating the user's balance with each buy or sell order.

Running Totals And Averages

Assignment operators are great runners - they don't tire and always keep the tally running.

Here, the '+=' and '-=' operators keep a running tally of points, allowing the system to adjust to the ebbs and flows of the school year like a seasoned marathon runner pacing themselves.

Iterations In Loop Constructs

The '*=' and '/=' operators often lurk within loop constructs, handling iterations with the grace of a prima ballerina. They're the choreographers of your loops, making sure each iteration flows seamlessly into the next.

In this case, '/=' is the elegant dancer gracefully halving 'i' with each twirl across the dance floor (iteration).

Working With Remainders

And let's not forget our mysterious '%=', the detective of the bunch, always searching for the remainder, the evidence left behind.

Here, '%=' is the sleuth, determining whether a number is even or odd by examining the remainder when divided by 2.

So, these are just a few examples of how assignment operators flex their muscles in the real world. They're like superheroes, each with their unique powers, ready to assist you in writing clean, efficient, and understandable code. Use them wisely, and your code will be as smooth as a well-choreographed ballet.

Let's face it, even the best of us trip over our own feet sometimes. And when it comes to assignment operators in C, there are some pitfalls that could make you stumble. But don't worry! We've all been there. Let's shed some light on these common mistakes so we can step over them with the grace of a ballet dancer leaping over a pit of snapping alligators.

Confusing Assignment With Equality

A surprisingly common misstep is confusing the assignment operator '=' with the equality operator '=='. It's like mixing up salt with sugar while baking. Sure, they might look similar, but one will definitely not sweeten your cake.

In this snippet, instead of checking if 'a' equals 10, we've assigned 'a' the value 10. The compiler will happily let this pass and might even give you a standing ovation for your comedy of errors. The correct approach?

Overlooking Operator Precedence

C operators are a bit like the characters in "Game of Thrones." They've got a complex hierarchy and they respect the rule of precedence. Sometimes, this can lead to unexpected results. For instance, check out this bit of misdirection:

Here, '/=' doesn't immediately divide 'a' by 2. It waits for the multiplication to happen (due to operator precedence), and then performs the operation. So it's actually doing a /= (2*5), not (a/=2)*5. It's like arriving late to a party and finding out all the pizza is gone. To ensure you get your slice, use parentheses:

Misusing Modulo With Floats

Ah, the modulo operator, always looking for the remainder. But when you ask it to work with floats, it gets as confused as a penguin in a desert. It simply can't compute.

Modulo and floats go together like oil and water. The solution? Stick to integers when dealing with '%='.

So there you have it. Some common missteps while dancing with assignment operators and the quick moves to avoid them. Just remember, every great coder has tripped before. The key is to keep your chin up, learn from your stumbles, and soon you'll be waltzing with assignment operators like a seasoned pro.

Alright, amigos! It's time to put your newfound knowledge to the test. After all, becoming a master in the art of C assignment operators is not a walk in the park, it's a marathon run on a stony path with occasional dance-offs. So brace yourselves and let's get those brain cells pumping.

Exercise 1: The Shy Variable

Your task here is to write a C program that initializes an integer variable to 10. Then, using only assignment operators, make that variable as shy as a teenager at their first dance. I mean, reduce it to zero without directly assigning it to zero. You might want to remember the '/=' operator here. He's like the high school wallflower who can suddenly breakdance like a champ when the music starts playing.

Exercise 2: Sneaky Increment

The '+=' operator is like the mischievous friend who always pushes you into the spotlight when you least expect it. Create a program that initializes an integer to 0. Then, using a loop and our sneaky '+=' friend, increment that variable until it's equal to 100. Here's the catch: You can't use '+=' with anything greater than 1. It's a slow and steady race to the finish line!

Exercise 3: Modulo Madness

Remember the modulo operator? It's like the friend who always knows how much pizza is left over after a party. Create a program that counts from 1 to 100. But here's the twist: for every number that's divisible by 3, print "Fizz", and for every number divisible by 5, print "Buzz". If a number is divisible by both 3 and 5, print "FizzBuzz". For all other numbers, just print the number. This will help you get better acquainted with our friend '%='.

Exercise 4: Swapping Values

Create a program that swaps the values of two variables without using a third temporary variable. Remember, your only allies here are the assignment operators. This is like trying to switch places on the dance floor without stepping on anyone's toes.

Exercise 5: Converting Fahrenheit To Celsius

Let's play with the ' =' operator. Write a program that converts a temperature in Fahrenheit to Celsius. The formula to convert Fahrenheit to Celsius is (Fahrenheit - 32) * 5 / 9 . As a challenge, try doing the conversion in a single line using the '-=', ' =' and '/=' operators. It's like preparing a complicated dinner recipe using only a few simple steps.

Remember, practice makes perfect, especially when it comes to mastering C assignment operators. Don't be disheartened if you stumble, just dust yourself off and try again. Because as the saying goes, "The master has failed more times than the beginner has even tried". So, good luck, and happy coding!

Java provides many types of operators to perform a variety of calculations and functions, such as logical , arithmetic , relational , and others. With so many operators to choose from, it helps to group them based on the type of functionality they provide. This programming tutorial will focus on Java’s numerous a ssignment operators.

Assignment Operators in Java

As the name conveys, assignment operators are used to assign values to a variable using the following syntax:

The left side operand of the assignment operator must be a variable, whereas the right side operand of the assignment operator may be a literal value or another variable. Moreover, the value or variable on the right side must be of the same data type of the operand on the left side. Otherwise, the compiler will raise an error. Assignment operators have a right to left associativity in that the value given on the right-hand side of the operator is assigned to the variable on the left. Therefore, the right-hand side variable must be declared before assignment.

You can learn more about variables in our programming tutorial: Working with Java Variables .

Types of Assignment Operators in Java

Java assignment operators are classified into two types: simple and compound .

The Simple assignment operator is the equals ( = ) sign, which is the most straightforward of the bunch. It simply assigns the value or variable on the right to the variable on the left.

Compound operators are comprised of both an arithmetic, bitwise, or shift operator in addition to the equals ( = ) sign.

Equals Operator (=) Java Example

First, let’s learn to use the one-and-only simple assignment operator – the Equals ( = ) operator – with the help of a Java program. It includes two assignments: a literal value to num1 and the num1 variable to num2 , after which both are printed to the console to show that the values have been assigned to the numbers:

The += Operator Java Example

A compound of the + and = operators, the += adds the current value of the variable on the left to the value on the right before assigning the result to the operand on the left. Here is some sample code to demonstrate how to use the += operator in Java:

The -= Operator Java Example

Made up of the – and = operators, the -= first subtracts the variable’s value on the right from the current value of the variable on the left before assigning the result to the operand on the left. We can see it at work below in the following code example showing how to decrement in Java using the -= operator:

The *= Operator Java Example

This Java operator is comprised of the * and = operators. It operates by multiplying the current value of the variable on the left to the value on the right and then assigning the result to the operand on the left. Here’s a program that shows the *= operator in action:

The /= Operator Java Example

A combination of the / and = operators, the /= Operator divides the current value of the variable on the left by the value on the right and then assigns the quotient to the operand on the left. Here is some example code showing how to use the  /= operator in Java:

%= Operator Java Example

The %= operator includes both the % and = operators. As seen in the program below, it divides the current value of the variable on the left by the value on the right and then assigns the remainder to the operand on the left:

Compound Bitwise and Shift Operators in Java

The Bitwise and Shift Operators that we just recently covered can also be utilized in compound form as seen in the list below:

• &= – Compound bitwise Assignment operator.
• ^= – Compound bitwise ^ assignment operator.
• >>= – Compound right shift assignment operator.
• >>>= – Compound right shift filled 0 assignment operator.
• <<= – Compound left shift assignment operator.

The following program demonstrates the working of all the Compound Bitwise and Shift Operators :

Final Thoughts on Java Assignment Operators

This programming tutorial presented an overview of Java’s simple and compound assignment Operators. An essential building block to any programming language, developers would be unable to store any data in their programs without them. Though not quite as indispensable as the equals operator, compound operators are great time savers, allowing you to perform arithmetic and bitwise operations and assignment in a single line of code.

Assignment Operators

Assignment operators play a pivotal role in programming by allowing developers to assign values to variables. These operators are fundamental to most programming languages, including C, C++, Java, etc. In this article, we will explore assignment operators, their types, and how they are used to manipulate data in programs.

An assignment operator consists of two operands: the left-side operand (a variable) and the right-side operand (a value). The operator aims to assign the value on the right side to the variable on the left side. However, there’s a crucial rule: the value’s data type on the right side must match the variable’s data type on the left side. If they don’t match, the compiler will generate an error.

Here is a list of common assignment operators:

• “=” (Simple Assignment Operator)

The most straightforward assignment operator, “=,” assigns the value on the right to the variable on the left. For instance:

int a = 10;

char ch = ‘y’;

In the first line, the variable a is assigned the value 10, while in the second line, the variable ch is assigned the character ‘y’.

• “+=” (Addition Assignment Operator)

The “+=” operator combines addition and assignment. It adds the current value of the variable on the left to the value on the right and assigns the result back to the variable on the left. It can be expressed as follows:

a += b; // Equivalent to a = a + b;

Suppose the initial value stored in a is 5. After executing (a += 6), a value becomes 11.

• “-=” (Subtraction Assignment Operator)

The “-=” operator combines subtraction and assignment. It subtracts the current value of the variable on the left from the value on the right and assigns the result back to the variable on the left. It can be expressed as follows:

a -= b; // Equivalent to a = a – b;

If the initial value stored in a is 8, after executing (a -= 6), a value becomes 2.

• “*=” (Multiplication Assignment Operator)

The “*=” operator combines multiplication and assignment. It multiplies the current value of the variable on the left by the value on the right and assigns the result back to the variable on the left. It can be expressed as follows:

a *= b; // Equivalent to a = a * b;

If the initial value stored in a is 5, after executing (a *= 6), a value becomes 30.

• “/=” (Division Assignment Operator)

The “/=” operator combines division and assignment. It divides the current value of the variable on the left by the value on the right and assigns the result back to the variable on the left. It can be expressed as follows:

a /= b; // Equivalent to a = a / b;

If the initial value stored in a is 6, after executing (a /= 2), a value becomes 3.

Putting Assignment Operators to Work

To demonstrate the use of assignment operators, let’s consider a simple C program:

#include <stdio.h>

int main() {

    int a = 10;

    printf(“Value of a is %d\n”, a);

    a += 10;

    a -= 10;

    a *= 10;

    a /= 10;

    return 0;

When executed, this program will output the following:

value of a is 10

value of a is 20

value of a is 100

This output illustrates how assignment operators modify variable A’s value through various arithmetic operations. Assignment operators are fundamental tools in programming, allowing developers to manipulate variables by assigning values based on different operations. Understanding these operators’ behavior is crucial for writing efficient and error-free code. As you continue your programming journey, you’ll encounter these operators frequently and become skilled at using them to build robust and dynamic applications.
