std::ranges...::operator[](3)

💅 NAME 💅

Bestie, the full name is std::ranges::enumerate_view::iterator::operator[] — and yeah, they listed it twice, so we're listing it twice too: std::ranges::enumerate_view::iterator::operator[]. It's giving "government name plus middle names plus confirmation name" energy, but we respect it 🫶. Also quick heads up, this page lives in the C++ Standard Libary manual — that's their spelling, not mine, we love them anyway ✨.

🌟 Synopsis 🌟

Okay so here's the whole entire vibe:

constexpr auto operator[]( difference_type n ) const  (since C++23)
    requires ranges::random_access_range<Base>

That (since C++23)? New era, fresh start, main character debut 💖. And the requires ranges::random_access_range<Base> line is the vibe check — your Base has to be a random access range or this whole function simply does not apply to you, periodt.

She returns an element at a specified relative location. Equivalent to:

return reference-type(pos_ + n, current_[n]);.

(Yeah the trailing period is part of it, keep it exactly, don't come for me 🙈.)

🎀 Parameters 🎀

• n — position relative to current location. That's the whole parameter, she's simple, she's effective, she's booked and busy.

🌸 Return value 🌸

The element at displacement n relative to the current location. You point at a spot, she hands you the element, iconic behavior honestly 💅.

🦋 Example 🦋

This section is incomplete Reason: no example

Not them leaving us on read 😭. No example yet bestie, we wait patiently, we stay hydrated 🍓.

👑 See also 👑

• operator* — accesses the element (C++23) (public member function). Your other bestie for getting your hands on the goods 🔥.

💜 Category 💜

• Todo: no example. Yeah they really said "figure it out yourself" 🙈 — same energy as the Example section, consistent queen.

That's the page, bestie! It's from the C++ Standard Libary manual over at cppreference.com, dated 2024.06.10, for std::ranges...::operator[](3). Go forth and random-access-range responsibly, ily, bye 🧚💖✨
