Assignment Operators in C

Assignment Operators

  •   “=”: This is the simplest assignment operator. This operator is used to assign the value on the right to the variable on the left.

for eg:-

a=5;

b=10

a will be assigned value of 5, and b will be assigned value of 10.

  •     “+=”:This operator is combination of ‘+’ and ‘=’ operators. This operator first adds the current value of the variable on left to the value on right and then assigns the result to the variable on the left.

eg; ( a+=b ) can written as( a=a+b )

  •   ” -=” This operator is combination ‘-‘ and ‘=’ operator. This operator subtracts the value on right from the current value of the variable on left and then assigns the result to the variable on the left.

eg; ( a-=b ) can written as( a=a-b )

Implementation of Assignment Operator

  • First of all in this program we will initialize the value in the variable, the we will assign the value of the right to the variable.
  • like a=20 means 20 will assign to the a variable.
  • b+=10 means b=b+10 and b=10 initialize so b=10+10 it means b=20 so 20 will assign to b.
  • c*=2 means c=c*2 that means multiply of 2*5 because the value of 5 is c so c=10 ,then 10 will assign to the C.

Code for Assignment operator in C

Run

#include <stdio.h> // header files
#include <stdlib.h> // library files

int main()// main function
{
int a,b=10,c=5;   // initialize the value
a=20;
b+=10;
c*=2;

printf("\n%d",b);
printf("\n%d",c);

return 0;
}

Output

20
10
