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

Return value

*this

Exceptions

2) Throws std::out_of_range if pos does not correspond to a valid bit position.

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';
}
