assert.h is a header file in the C standard library. It defines the C preprocessor macro assert and implements runtime assertion in C. assert.h is defined in ANSI C as part of the C standard library. In the C++ programming language, assert.h and < cassert > are available; both are functionally equivalent. [1]
An example of _MSC_VER is 1933 to represent version 19.33 of the Microsoft C/C++ compiler, and of _MSC_FULL_VER is 193331630. The Visual product version, such as "17.3.4", designates the version of Visual Studio with which version 19.33 of the compiler was packaged. Then there is the Microsoft Visual C/C++ Runtime Library version, e.g. "14.3".
When an assertion failure occurs, the programmer is immediately notified of the problem. Many assertion implementations will also halt the program's execution: this is useful, since if the program continued to run after an assertion violation occurred, it might corrupt its state and make the cause of the problem more difficult to locate.
C++/WinRT is an entirely standard modern C++17 language projection for Windows Runtime (WinRT) APIs, implemented as a header-file-based library, and designed to provide first-class access to the modern Windows API. With C++/WinRT, Windows Runtime APIs can be authored and consumed using any standards-compliant C++17 compiler.
This runtime library is used by programs written in Visual C++ and a few other compilers (e.g. MinGW). Some compilers have their own runtime libraries. With Version 14.0 (Visual Studio 2015), most of the C/C++ runtime was moved into a new DLL, UCRTBASE.DLL, which conforms closely with C99.
Microsoft C run-time library, part of Microsoft Visual C++. There are two versions of the library: MSVCRT that was a redistributable till v12 / Visual Studio 2013 with low C99 compliance, and a new one UCRT (Universal C Run Time) that is part of Windows 10 and 11, so always present to link against, and is C99 compliant too [1] .
The Metacode extension to C++ (Vandevoorde 2003) [1] was an early experimental system to allow compile-time function evaluation (CTFE) and code injection as an improved syntax for C++ template metaprogramming. In earlier versions of C++, template metaprogramming is often used to compute values at compile time, such as:
Therefore, a runtime library is always specific to the platform and compiler. The runtime library may implement a portion of the runtime environment's behavior, but if one reads the code of the calls available, they are typically only thin wrappers that simply package information, and send it to the runtime environment or operating system ...
