bitset::flip

public member function
bitset<N>& flip ( );
bitset<N>& flip ( size_t pos );

Flip bits

The version with no parameters flips all the bits in the bitset, i.e. changes all 0s for 1s and all 1s for 0s.
The parameterized version, flips only the bit at position pos.

The unary operator~ performs the same operation as flip().

Parameters

pos
Order position of the bit whose value is flipped.
Order positions are counted from the rightmost bit, which is order position 0.
size_t is an unsigned integral type.

Return value

*this
If pos is not a valid bit position, out_of_range is thrown.
