std::bitset<N>::flip
(1) | ||
bitset& flip(); |
(until C++11) | |
bitset& flip() noexcept; |
(since C++11) | |
bitset& flip( std::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
Example
#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
