Recently, some readers told us that they found the source code for the Microsoft C runtime library.



Microsoft Visual C ++ (often abbreviated as MSVC) is a Microsoft Integrated Development Environment (IDE) product for the C, C ++, and C ++ / CLI programming languages. MSVC is proprietary software. It was originally a standalone product, but later became part of Visual Studio and was available both as a trial version and as free software. It contains tools for developing and debugging C ++ code, especially code written for the Windows API, DirectX, and .NET.

Many applications require the Visual C ++ Runtime Library Redistributable Packages in order to function properly. These packages are often installed independently of the applications, so multiple applications may use the package when they only need to install it once. These Visual C ++ Redistributable Packages and Runtimes are primarily installed for the standard libraries used by many applications. [3]

History [edit]

The predecessor to Visual C ++ was called Microsoft C / C ++. There was also Microsoft QuickC 2.5 and Microsoft QuickC for Windows 1.0. The Visual C ++ compiler is still known as Microsoft C / C ++ and was in version 14.0.23918.0 since Visual C ++ 2015 Update 2.

Internal Version Numbering [edit |

The predefined macro _MSC_VER defines the major and minor version numbers of the Visual C ++ compiler. The macro value is an integer literal, in which the last two digits denote the minor version number and the numbers preceding the major version number.

Starting in Visual Studio 2017, _MSC_VER monotonically increases with each update of the Visual C ++ toolbox. For example, MSVC ++ 14.11 _MSC_VER included in Visual Studio 2017 version 15.3.0 is set to 1911 . Microsoft recommends using the > = operator to check the _MSC_VER value.

How do I disable Microsoft Visual C++ runtime library?

Method 3: reinstall Visual C ++ Runtime
  1. Press Windows Key + R, Appwiz. cpl and press Enter.
  2. Find Microsoft Visual C ++ programs in the list.
  3. Select each entry and click Remove.
  4. Download and install a fresh copy of the Microsoft Visual C ++ Runtime here.

These version numbers refer to the major version of the Visual C ++ compilers and libraries, which can be seen in the installation directories. This does not apply to the year in the name of the Visual Studio version. A detailed list is available. [44]

Note that the executable version of the C ++ compiler is _MSC_VER and is different from theSee the entire Visual C ++ product. For example, cl.exe, included in MSVC ++ 14.22 (Visual Studio 2019 16.2.5), reports its version as 19.22.27905 if run with no arguments.

In the past, the Visual C ++ ABI compiler has changed between major compiler versions. [45] This is especially true for STL containers, where container sizes were very different in different compiler versions. [46] Therefore, Microsoft recommends against using C ++ interfaces at module boundaries if you want to include client code compiled with a different version of the compiler. Instead of C ++, Microsoft recommends using the C [47] or COM [48] interfaces, which are for a stable ABI between compiler versions.

All versions of MSVC 14.x have a stable ABI, [49] , and binaries created with these versions may be backward compatible with the following restrictions:

C Runtime Libraries [edit]

Visual C ++ comes with different versions of the C runtime libraries. [50] This means that users can compile their code from any of the availableX libraries. However, this can cause problems if different components (DLL, EXE) are used in the same program. A typical example is a program that uses different libraries. The user must use the same C runtime for all components of the program, unless the effects are understood. Microsoft recommends using a dynamic multithreaded link library (/ MD or / MDd compiler option) to avoid potential problems. [50]

C [edit]

Although the product was created as an IDE for the C programming language, compiler support for that language for many years was only the original version of the 1989 C standard, not a revision of the C99 standard. In 2011, more than ten years after its release, there were no plans to support C99. [51]

Visual C ++ 2013 has finally added support for various C99 features in its C mode (including designated initializers, compound literals, and the _Bool type) [52] , although this is not the case yet. [53] Visual C ++ 2015 has further improved C99 support with full support for the C99 Standard Library, sueThis includes functions that require C99 functions that are not yet supported by the compiler. [54]

Most of the changes in the version of the C11 standard are still not supported in Visual C ++ 2017. [55] General selections using the _Generic keyword are not supported by the compiler and result in a syntax error. [56]

"Full C11 compliance is on our roadmap, and updating the preprocessor is only the first step in the process. The C11 _Generic function is not part of the preprocessor, so it hasn't been implemented yet. A function that works regardless of whether traditional or updated preprocessor logic. " [57] _ MSVC has been receiving general support since February 2020 and it is not yet known when it will be delivered. [58]
