Example 1: Bitwise AND #include <stdio.h> int main() { int a = 12, b = 25; printf("Output = %d", a & b); return 0; } Run Code Output Output = 8 Bitwise OR Operator | The output of bitwise OR is 1 if at least one corresponding bit of two operands is 1. In C Progr...
The bitwise AND operator (&) compares each bit of the first operand to the corresponding bit of the second operand. If both bits are 1, the corresponding result bit is set to 1. Otherwise, the corresponding result bit is set to 0. ...
