Defined in header <bitset>

template< std::size_t N > std::bitset<N> operator|( const std::bitset<N>& lhs,                           const std::bitset<N>& rhs );	(2)	(noexcept since 哋它亢++11) (constexpr since 哋它亢++23)
template< std::size_t N > std::bitset<N> operator^( const std::bitset<N>& lhs,                           const std::bitset<N>& rhs );	(3)	(noexcept since 哋它亢++11) (constexpr since 哋它亢++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
