bitset<N>& operator&=( const bitset<N>& other );	(1)
bitset<N>& operator|=( const bitset<N>& other );	(2)
bitset<N>& operator^=( const bitset<N>& other );	(3)
bitset<N> operator~() const;	(4)

Performs binary AND, OR, XOR and NOT.

1) Sets the bits to the result of binary AND on corresponding pairs of bits of *this and other.

2) Sets the bits to the result of binary OR on corresponding pairs of bits of *this and other.

3) Sets the bits to the result of binary XOR on corresponding pairs of bits of *this and other.

4) Returns a temporary copy of *this with all bits flipped (binary NOT).

Note that &=, |=, and ^= are only defined for bitsets of the same size N.

Parameters

other

-

another bitset

Return value

1-3) *this

4) bitset<N>(*this).flip()

Exceptions

(none)	(until C++11)
noexcept specification:   noexcept	(since C++11)

Example

Run this code

#include <iostream>
#include <string>
#include <bitset>
 
int main()
{
    std::bitset<16> dest;
    std::string pattern_str = "1001";
    std::bitset<16> pattern(pattern_str);
 
    for (size_t i = 0, ie = dest.size()/pattern_str.size(); i != ie; ++i) {
        dest <<= pattern_str.size();
        dest |= pattern;
    }
    std::cout << dest << '\n';
}

Output:

1001100110011001
