std::bitset::flip
From cppreference.com
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 (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
1)
(none) | (until C++11) |
noexcept specification: noexcept |
(since C++11) |
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
