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.

[edit] Parameters

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

[edit] Return value

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

[edit] Example

#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
