WebMay 2, 2024 · Basically, you have an XY problem; a properly designed constructor could initialize your bitset s correctly from the start (before you reach the constructor body) from provided argument (s), so you're default-initializing them only to replace the values in the constructor body. 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 .
