Synopsis
template <std::size_t N>
(1)
bitset<N>
operator&(const bitset<N> &lhs, const bitset<N> &rhs);
template <std::size_t N>
(2)
bitset<N>
operator|(const bitset<N> &lhs, const bitset<N> &rhs);
template <std::size_t N>
(3)
bitset<N>
operator^(const bitset<N> &lhs, const bitset<N> &rhs);Performs binary AND, OR, and XOR between two bitsets, lhs and rhs.
1) Returns a bitset<N> containing the result of binary AND on corresponding pairs of bits of lhs and rhs.
2) Returns a bitset<N> containing the result of binary OR on corresponding pairs of bits of lhs and rhs.
3) Returns a 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) bitset<N>(lhs) &= rhs
2) bitset<N>(lhs) |= rhs
3) bitset<N>(lhs) ^= rhs
Exceptions

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';
}
