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

💖 NAME 💖

std::experimental::shared_ptr::operator[] - std::experimental::shared_ptr::operator[] 💅

Okay bestie, this is the std::experi...::operator[](3) page from the C++ Standard Libary manual — yes, “Libary” is literally how it’s spelled in the header, and we are not fixing it. This page is all about std::experimental::shared_ptr::operator[], and it’s here to index into an array. 🦋

✨ Synopsis ✨

element_type& operator[]( std::ptrdiff_t i ) const
noexcept;

Tagged (library fundamentals TS), bestie. This operator indexes into the array pointed to by the stored pointer. No cap.

🚨 Behavior check: the behavior is undefined if the stored pointer is null or if i is negative. Like, undefined undefined. Do not test that vibe. 😭

And if T (the template parameter of shared_ptr) is an array type U[N], then i shall be less than N, or the behavior is undefined. Periodt.

🌸 Parameters 🌸

• i — the array index.

🎀 Return value 🎀

A reference to the i-th element of the array, i.e., get()[i]. Slay. 💖

👑 Remarks 👑

Okay so here’s the chaotic little caveat: when T is not an array type, it is unspecified whether this function is declared. If the function is declared, it is unspecified what its return type is, except that the declaration (although not necessarily the definition) of the function is guaranteed to be legal. That’s the whole rule. Iykyk. 🧚
