std::flat_multiset::size(3)

Hey bestie 💖 this is the std::flat_multiset::size(3) page from the C++ Standard Libary manual. It’s short, it’s cute, it’s giving “one method, no drama” energy ✨

💖 NAME 💖

std::flat_multiset::size — literally std::flat_multiset::size, that’s the name, that’s the vibe, we move 💅

🌸 Synopsis 🌸

size_type size() const noexcept;

(since C++23) ✨

Returns the number of elements in the container adaptor. Equivalent to return c.size();.

🎀 Parameters 🎀

(none) — not a single parameter, she takes no arguments 🙈

🦋 Return value 🦋

The number of elements in the container adaptor. Periodt 💖

⭐ Complexity ⭐

Constant. No scrolling, no stress, just constant vibes 🔥

🌈 Example 🌈

The following code uses size to display the number of elements in a std::flat_multiset<int>:

// Run this code

#include <iostream>
#include <flat_set>

int main()
{
    std::flat_multiset<int> nums{1, 3, 5, 7};

    std::cout << "nums contains " << nums.size() << " elements.\n";
}

Output:

nums contains 4 elements.
