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.
For Visual C++, Visual Studio adds a new version of Microsoft Foundation Classes (MFC 9.0) that adds support for the visual styles and UI controls introduced with Windows Vista. [143] For native and managed code interoperability, Visual C++ introduces the STL/CLR, which is a port of the C++ Standard Template Library (STL) containers and ...
ATL version 7 also introduced attributes in C++ in an attempt to provide something similar to CLI attributes, however these have not been particularly successful, and have been deemphasized in ATL version 8 (Visual Studio 2005); the various wizards no longer generate them by default. Version 7 also introduced new string conversion classes.
The restrict type qualifier defined in C99 was not included in the C++03 standard, but most mainstream compilers such as the GNU Compiler Collection, [18] Microsoft Visual C++, and Intel C++ Compiler provide similar functionality as an extension. Array parameter qualifiers in functions are supported in C but not C++.
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 .
MFC was introduced in 1992 with Microsoft's C/C++ 7.0 compiler for use with 16-bit versions of Windows as an extremely thin object-oriented C++ wrapper for the Windows API. C++ was just beginning to replace C for development of commercial application software at the time.
The name has the potential to change at future versions, but has not done so as far as of Version 17.0. Source code for runtime libraries is included in Visual C++ [19] for reference and debugging (e.g. in C:\Program Files\Microsoft Visual Studio 11.0\VC\crt\src).
Porting over applications to the .NET Framework from C or C++ is much easier to do using Managed C++. The Microsoft Visual C++ .NET compiler, which compiles Managed C++ to target the .NET Framework, produces a much more matured set of instructions in its resultant assembly, thus improving performance.
