Webthe deduced type will not be a reference, only the base type bitset<4>. This means b3 is not a reference, and all modifications of b3 or its contents will be limited to the b3 object itself. To get a reference you need to explicitly use & in the declaration: auto& b3 = f.get_b1_ref (); Share Improve this answer Follow answered Nov 7, 2024 at 12:47 WebJun 10, 2011 · The bitset class stores the bits in a compact representations, e.g. in a char array, typically 8 bits per char (but YMMV on "exotic" platforms).

WebThe dynamic_bitsetclass represents a set of bits. provides accesses to the value of individual bits via an operator[]and provides all of the bitwise operators that one can apply to builtin integers, such as operator&and operator<<. The number of bits in the set is specified at runtime via a parameter to the constructor of the dynamic_bitset. 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.
