std::initia...list::begin(3)

✨ NAME ✨

okay so this is std::initia...list::begin(3), bestie — the std::initializer_list::begin page from the C++ Standard Libary. The NAME is literally std::initializer_list::begin - std::initializer_list::begin, because it ate and left no crumbs. 💅

🌸 Synopsis 🌸

const T* begin() const noexcept;            (since C++11)
                                            (until C++14)
constexpr const T* begin() const noexcept;  (since C++14)

Returns a pointer to the first element in the initializer list. 🫶

⚠️ If the initializer list is empty, the values of begin() and end() are unspecified, but will be identical. No cap — they’ll match, the actual value just isn’t promised. 😭

🎀 Parameters 🎀

• (none) — literally none, bestie. ✨

🦋 Return value 🦋

a pointer to the first element in the initializer list — iconic pointer behavior, fr fr. 💖

🔥 Complexity 🔥

Constant. That’s it. Periodt. 💀

🌈 Example 🌈

// Run this code

#include <initializer_list>

int main()
{
    static constexpr auto il = {42, 24};
    static_assert(*il.begin() == 0x2A);
}

• end — returns a pointer to one past the last element (public member function). Obsessed with the symmetry. ✨
