std::bitset::size(3)

✨ NAME ✨

okay so bestie, this is std::bitset::size(3) — the NAME section literally says std::bitset::size, and honestly it’s just std::bitset::size, a self-love moment 💅. it comes from the C++ Standard Libary manual (that’s the manual name, folded in right here instead of copying the header line, periodt).

🌸 Synopsis 🌸

the signature is right here with since-C++11 glow-up energy:

          std::size_t size() const;  (noexcept since C++11)
                                     (constexpr since C++11)

Returns the number of bits that the bitset holds. that’s it, that’s the whole function ✨.

🎀 Parameters 🎀

(none) — she takes no parameters, not a single one, literally none 🙈.

💖 Return value 💖

the number of bits that the bitset holds, i.e. the template parameter N. no cap, that’s the return value.

🦋 Example 🦋

here’s the code, bestie — run it and watch it eat:

       // Run this code

        #include <bitset>
        #include <iostream>

        int main()
        {
            std::cout << std::bitset<0x400>().size() << '\n';
        }

Output:

        1024

• count — returns the number of bits set to true (public member function). iconic adjacent behavior, ngl.
