bitset& flip();
(1) (noexcept since C++11)
(constexpr since C++23)
bitset& flip( std::size_t pos );
(2) (constexpr since C++23)

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.

[edit] Parameters

pos - the position of the bit to flip

[edit] Return value

*this

[edit] Exceptions

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

[edit] Example

#include <bitset>
#include <iostream>
 
int main()
{
    std::bitset<4> flops;
 
    std::cout << flops << '\n'
              << flops.flip(0) << '\n'
              << flops.flip(2) << '\n'
              << flops.flip() << '\n';
}

Output:

0000
0001
0101
1010
