Usage

• alternative operators: as an alternative for ^

Example

Run this code

#include <bitset>
#include <iostream>
 
using bin = std::bitset<8>;
 
void show(bin z, const char* s, int n)
{
    if (n == 0) std::cout << "┌─────────┬──────────┐\n";
    if (n <= 2) std::cout << "│ "<<s<<" │ " <<z<<" │\n";
    if (n == 2) std::cout << "└─────────┴──────────┘\n";
}
 
int main()
{
    bin x{"01011010"}; show(x, "x      ", 0);
    bin y{"00111100"}; show(y, "y      ", 1);
    bin z = x xor y;   show(z, "x xor y", 2);
}

Output:

┌─────────┬──────────┐
│ x       │ 01011010 │
│ y       │ 00111100 │
│ x xor y │ 01100110 │
└─────────┴──────────┘
