Assignment Operators

Assignment Operators

They are used to assign the result of an expression to a variable.

Syntax

identifier = Expression

There are five assignment operators. They are,

a=a+1 a+=1

a=a- 1 a-= 1

a=a*2 a*=2

a=a/2 a/= 2

a=a%2 a%=2

Advantages:

• Left-hand side operator need not repeated.
• Easy to Read
• More Efficient

Example For C assignment operator

#include <stdio.h>

// C assignment operator Example Program

void main(){
  int a = 10;

  // = Operator
  int b = a;
  printf("b = %d\n",b);

  // += Operator
  b += 10;
  printf("b += 10;b = %d\n",b);

  // -= Operator
  b -=5;
  printf("b -=5;b = %d\n",b);

  // *= Operator
  b *=4;
  printf("b *=4;b = %d\n",b);

  // /= Operator
  b /=2;
  printf("b /=2;b = %d\n",b);
}

Sample Output:

b = 10

b += 10;b = 20

b -=5;b = 15

b *=4;b = 60

b /=2;b = 30

How It Works

This C program demonstrates Assignment Operators. It first prepares the data it needs, then performs the core operation step by step, and finally prints the output shown in the Sample Output above.

1. Declare the variables that hold the program’s data.
2. Print the final result to the console so you can compare it with the sample output.

Try changing the input values and re-running the program to see how the output changes — this is the fastest way to understand how the logic behaves.
