The template class describes an object that stores a sequence of N
bits. A bit is set if its value is 1, reset if its value is
0. To flip a bit is to change its value from 1 to 0 or from 0 to 1. When converting between an object of class
bitset<N>
and an object of some integral type, bit position j
corresponds to the bit value 1 << j
. The integral value
corresponding to two or more bits is the sum of their bit values.
