What is Bitwise XOR in C++?

The bitwise exclusive OR operator (^) compares every bit of} its 1st operand to the corresponding bit of its second operand. If one bit is 0 and the other bit is 1, the corresponding result bit is set to 1. Otherwise, the corresponding result bit is set to 0. Both operands to the bitwise exclusive OR operator must be of integral types. For example,

Example

#include <iostream>  
using namespace std;  

int main() {  
   unsigned short a = 0x5555;      // pattern 0101 ...  
   unsigned short b = 0xFFFF;      // pattern 1111 ...  
   cout  << hex << ( a ^ b ) << endl;
}

Output

This gives the output −

aaaa

Which represents the pattern 1010...
