The std::vector<bool> interface is very different from std::bitset. If you want to be able to write code in a similar manner, you can create a wrapper on std::vector<bool>, which looks like std::bitset, where possible. The following implementation provides members similar to what is available in std::bitset:

    class bitvector    {      std::vector<bool> bv;    public:      bitvector(std::vector<bool> const & bv) : bv(bv) {}      bool operator[](size_t const i) { return bv[i]; }      inline bool any() const {        for (auto b : bv) if (b) return true;          return false;      }      inline bool all() const {        for (auto b : bv) if (!b) return false;          return true;      }      inline bool none() const { return !any(); }      inline size_t count() const { return std::count(bv.cbegin(), bv.cend(), ...
