WebA bit array (also known as bitmask, [1] bit map, bit set, bit string, or bit vector) is an array data structure that compactly stores bits. It can be used to implement a simple set data structure. A bit array is effective at exploiting bit-level parallelism in hardware to perform operations quickly.
WebSep 29, 2024 · Bitset Function objects Partial function application (e.g. std::bind) and related utilities: utilities for binding such as std::ref and std::placeholders, polymorphic function wrappers: std::function, predefined functors (e.g. std::plus, std::equal_to ), pointer-to-member to function converters std::mem_fn . Hash support Date and time 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, …
WebHash for bitset Unary function object class that defines the hash specialization for bitset. The functional call returns a hash value based on the bitset passed as argument: A hash value is a value that depends solely on its argument, returning always the same value for the same argument (for a given program execution).
