Bitset atomic

WebResets bits to zero: (1) all bits Resets (to zero) all bits in the bitset. (2) single bit Resets (to zero) the bit at position pos. Parameters pos Order position of the bit whose value is modified. Order positions are counted from the rightmost bit, which is order position 0. If pos is equal or greater than the bitset size, an out_of_range exception is thrown. WebApr 3, 2024 · C++ bitset and its application. A bitset is an array of bools but each boolean value is not stored in a separate byte instead, bitset optimizes the space such that each boolean value takes 1-bit space only, so space taken by bitset is less than that of an array of bool or vector of bool . A limitation of the bitset is that size must be known at ...
