WebAug 13, 2024 · 1. A bitset stores bits (elements with only two possible values: 0 or 1). We can however get the part of a string by providing positions to bitset constructor (Positions are with respect to string position from left to right) 2. We can construct a bitset using the characters in the std::basic_string _str. WebALX23z • 2 yr. ago. Bitset usually uses some underlying default integer for containing data. So in your case bitset<1>, bitset<32>, bitset<64> will be of the same size. Using such an integer is definitely more efficient for larger bitset sizes - for variety of reasons - but I cannot say much for size of 8.
