std::back_i...::operator++(3)

okay bestie, welcome to std::back_i...::operator++(3) from the C++ Standard Libary manual 💅 this one is short, sweet, and lowkey iconic.

💖 NAME 💖

std::back_insert_iterator::operator++ - std::back_insert_iterator::operator++

(no cap, it's literally the same name twice and we're gonna roll with it ✨)

✨ Synopsis ✨

back_insert_iterator& operator++();                (until C++20)
constexpr back_insert_iterator& operator++();      (since C++20)
back_insert_iterator operator++( int );            (until C++20)
constexpr back_insert_iterator operator++( int );  (since C++20)

Okay so plot twist: this operator does nothing 💀 like, genuinely nothing. These operator overloads are provided to satisfy the requirements of LegacyOutputIterator.

They make it possible for the expressions *iter++=value and *++iter=value to be used to output (insert) a value into the underlying container. That's the whole vibe check 🦋

🎀 Parameters 🎀

(none) — zero, nada, no arguments, no drama 🫶

🫶 Return value 🫶

*this — that's it, that's the answer, periodt 💅
