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

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
