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) |
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
