In a C language there are following assignment operators −
| Operator | Description | Example |
|---|---|---|
| = | assignment operator (it assigns values of right side operands to left side operand ) | a=5 |
| += | Add assignment operator | a+=5 |
| -= | Subtract assignment operator | a-=5 |
| *= | Multiply assignment operator | a*=5 |
| /= | Divide assignment operator | a/=5 |
| %= | Modulus assignment operator | a%=5 |
| <<= | Left shift assignment operator | a<<=5 |
| >>= | Right shift assignment operator | a>>=5 |
| &= | Bitwise AND assignment operator | a&=5 |
| ^= | Bitwise exclusive OR assignment operator | a^=5 |
| |= | Bitwise inclusive OR assignment operator | a|=5 |
EXAMPLE: Use of assignment operators with arithmetic operators
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 | #include <stdio.h> int main() { int a = 10; a +=5; // 15 (a=a+5) printf("\nsum is %d",a); a-=5; //10 (a=a-5) printf("\nsub is %d",a); a*=5; //50 (a=a*5) printf("\nmul is %d",a); a/=5; //10 (a=a/5) printf("\ndiv is %d",a); a%=5; printf("\nmod is %d",a); return 0; } |
Output
1 2 3 4 5 | sum is 15 sub is 10 mul is 50 div is 10 mod is 0 |
EXAMPLE: Use of assignment operators with bitwise operators
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 | # include < stdio.h > int main() { int a = 10; a <<= 2; // 15 (a=a+5) printf("\nleft shift is %d", a); a >>= 2; //10 (a=a-5) printf("\nright shift is %d", a); a &= 2; //50 (a=a*5) printf("\nbitwise and is %d", a); a ^= 2; //10 (a=a/5) printf("\nbitwise xor is %d", a); a |= 2; printf("\nbitwise or is %d", a); return 0; } |
Output
1 2 3 4 5 | left shift is 40 right shift is 10 bitwise and is 2 bitwise xor is 0 bitwise or is 2 |
