c++ print number in binary code example

Example 1: c++ print byte as bit

#include <bitset>
...

char a = -58;    
std::bitset<8> x(a);
std::cout << x << '\n';

short c = -315;
std::bitset<16> y(c);
std::cout << y << '\n';

Example 2: c++ display numbers as binary

#include <iostream>
#include <bitset>

int main() {
    int a = -58, b = a>>3, c = -315;

    std::cout << "a = " << std::bitset<8>(a)  << std::endl;
    std::cout << "b = " << std::bitset<8>(b)  << std::endl;
    std::cout << "c = " << std::bitset<16>(c) << std::endl;
}
