Any new expression that uses the placement syntax is a placement new expression, and any operator new or operator delete function that takes more than the mandatory first parameter (std:: size_t) is a placement new or placement delete function. [4] A placement new function takes two input parameters: std:: size_t and void *.
Except for a form called the "placement new", the new operator denotes a request for memory allocation on a process's heap.If sufficient memory is available, new initialises the memory, calling object constructors if necessary, and returns the address to the newly allocated and initialised memory.
The C++ programming language includes these functions; however, the operators new and delete provide similar functionality and are recommended by that language's authors. [4] Still, there are several situations in which using new / delete is not applicable, such as garbage collection code or performance-sensitive code, and a combination of ...
[8] [9] The current purpose of allocators is to give the programmer control over memory allocation within containers, rather than to adapt the address model of the underlying hardware. In fact, the revised standard eliminated the ability of allocators to represent extensions to the C++ address model, formally (and deliberately) eliminating ...
C++20 replaced the prior version of the C++ standard, called C++17, and was later replaced by C++23. [1] The standard was technically finalized [2] by WG21 at the meeting in Prague in February 2020, [3] had its final draft version announced in March 2020, [4] was approved on 4 September 2020, [5] [6] and published in December 2020.

In computer programming, indentation style is a convention, a.k.a. style, governing the indentation of blocks of source code.An indentation style generally involves consistent width of whitespace (indentation size) before each line of a block, so that the lines of code appear to be related, and dictates whether to use space or tab characters for the indentation whitespace.
Microsoft Visual C++ (MSVC) is a compiler for the C, C++, C++/CLI and C++/CX programming languages by Microsoft. MSVC is proprietary software ; it was originally a standalone product but later became a part of Visual Studio and made available in both trialware and freeware forms.
