Bit operators / ^ - bitwise XOR (exclusive OR) / Essential C++

#include <iostream>
#include <string>

int main(int argc, char **argv) {
    int a = 5;     // 0101b  (0x05)
    int b = 9;     // 1001b  (0x09)
    int c = a ^ b; // 1100b  (0x0C)
    
    std::cout << "a = " << a << ", b = " << b << ", c = " << c << std::endl;
}
