WebJun 17, 2024 · A bitset is an array of boolean values, but each boolean value is not stored separately. Instead, bitset optimizes the space such that each bool takes 1-bit space only, so space taken by bitset say, bs is less than that of bool bs [N] and vector bs (N). WebFeb 12, 2024 · You can use an std::bitset::operator[] to access the specifit bit. Keep in mind though, that [0] means the least significant bit, but we want to store them in the most significant -> least significant order, so we have to use the 7 - j instead of simply j:. #include #include int main() { constexpr int SIZE = 5; std::bitset<8> …
