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 ... WebReturns whether any of the bits is set (i.e., whether at least one bit in the bitset is set to one). This is the opposite of bitset::none. Parameters none Return value true if any of the …

std::bitset has a to_string() method for serializing as a char-based string of 1s and 0s.Obviously, this uses a single 8 bit char for each bit in the bitset, making the serialized representation 8 times longer than necessary.
