WebA bitset stores bits (elements with only two possible values: 0 or 1, true or false, ...). The class emulates an array of bool elements, but optimized for space allocation: generally, each element occupies only one bit (which, on most systems, is eight times less than the smallest elemental type: char). Each bit position can be accessed individually: for example, for a … WebOct 20, 2012 · The above won't count the number of bits in a character, it will count the number of set bits (1 bits). For example, the following call will return 4: char c = 'U'; countbits (c); The code: ch = ch & (ch - 1) Is a trick to strip off the right most (least significant) bit that's set to 1. So, it glosses over any bits set to 0 and doesn't count them.
