Defined in header <bitset>
template<std::size_t N > std::bitset<N> operator&(conststd::bitset<N>& lhs,                           conststd::bitset<N>& rhs );	(1)	(noexcept since C++11) (constexpr since C++23)
template<std::size_t N > std::bitset<N> operator|(conststd::bitset<N>& lhs,                           conststd::bitset<N>& rhs );	(2)	(noexcept since C++11) (constexpr since C++23)
template<std::size_t N > std::bitset<N> operator^(conststd::bitset<N>& lhs,                           conststd::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
