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
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
