Helper classes

std::hash (C++11)

 

bitset<N>& flip();	(1)
bitset<N>& flip( 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 (equivalent to operator~)

2) Flips the bit at the position pos.

Parameters

pos

-

the position of the bit to flip

Return value

*this

Exceptions

1)

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

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
