std::bitset
Defined in header <bitset>
template < std::size_t N >

std::bitset <N> operator& ( const std::bitset <N> & lhs,

const std::bitset <N> & rhs ) ;
(1) (noexcept since C++11)
(constexpr since C++23)
template < std::size_t N >

std::bitset <N> operator| ( const std::bitset <N> & lhs,

const std::bitset <N> & rhs ) ;
(2) (noexcept since C++11)
(constexpr since C++23)
template < std::size_t N >

std::bitset <N> operator^ ( const std::bitset <N> & lhs,

const std::bitset <N> & rhs ) ;
(3) (noexcept since C++11)
(constexpr since C++23)

Performs binary AND, OR, and XOR between two bitsets, lhs and rhs.

1) Returns a std::bitset<N> containing the result of binary AND on corresponding pairs of bits of lhs and rhs
2) Returns a std::bitset<N> containing the result of binary OR on corresponding pairs of bits of lhs and rhs
3) Returns a std::bitset<N> containing the result of binary XOR on corresponding pairs of bits of lhs and rhs

Parameters

lhs - the bitset on the left-hand side of the operator
rhs - the bitset on the right-hand side of the operator

Return value

1) std::bitset <N> (lhs) & =
2) std::bitset <N> (lhs) | =
3) std::bitset <N> (lhs) ^ =

Example

Run this code
#include <bitset>
#include <iostream>
 
int main()
{
    std::bitset<4> b1("0110");
    std::bitset<4> b2("0011");
 
    std::cout << "b1 & b2: " << (b1 & b2) << '\n';
    std::cout << "b1 | b2: " << (b1 | b2) << '\n';
    std::cout << "b1 ^ b2: " << (b1 ^ b2) << '\n';
}

Output: 

b1 & b2: 0010
b1 | b2: 0111
b1 ^ b2: 0101
