std::bitset::flip(3) C++ Standard Libary std::bitset::flip(3)

NAME

std::bitset::flip - std::bitset::flip

Synopsis


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.

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 <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
