std::bitset::flip (3) Linux Manual Page

std::bitset<N>::flip – std::bitset<N>::flip

Synopsis

bitset<N>& flip(); (until C++11)
bitset<N>& flip() noexcept; (1) (since C++11)
bitset<N>& flip( std::size_t pos ); (2)
Flips bits, i.e. changes true values to false and false values to true. Equivalent to a logical NOT operation on part or all of the bitset.
1) Flips all bits (like operator~, but in-place)
2) Flips the bit at the position pos.

Parameters

pos – the position of the bit to flip

Return value

*this

Exceptions

2) throws std::out_of_range if pos does not correspond to a valid position within the bitset.

Example

// Run this code

#include <iostream>

#include <bitset>
int main()

{
    std::bitset<4> b;
    std::cout << b << "\n";
    std::cout << b.flip(0) << '\n';
    std::cout << b.flip(2) << '\n';
    std::cout << b.flip() << '\n';
}

Output:

  0000
  0001
  0101
  1010
