std::initializer_list::end(3)

💖 std::initializer_list::end(3) 💖

okay so this is the C++ Standard Libary page, bestie — manual name folded in, no cap. We're talking about std::initializer_list::end(3) and it's lowkey iconic.

---

🎀 NAME 🎀

std::initializer_list::end — std::initializer_list::end. That's the name, fr fr. The page is named after itself and honestly? main character energy.

---

✨ Synopsis ✨

Two flavors, depending on your C++ era 👑:

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

So the synopsis says: returns a pointer to one past the last element in the initializer list, i.e. begin()+size().

If the initializer list is empty, the values of begin() and end() are unspecified, but will be identical. Read that again: unspecified but identical — that's the rule, periodt.

🫶 Parameters 🫶

(none) — literally no parameters. Not me checking twice 😭.

---

🌸 Return value 🌸

a pointer to one past the last element in the initializer list. That's the whole vibe.

---

🦋 Complexity 🦋

Constant — that's it, no extra lore.

---

🔥 Example 🔥

Run this code, bestie (// Run this code energy):

#include <numeric>
#include <initializer_list>

int main()
{
    static constexpr auto l = {15, 14};
    static_assert(std::accumulate(l.begin(), l.end(), 13) == 42);
}
