_MSC_VER Visual Studio Versions

_MSC_VER Defined as an integer literal that encodes the major and minor number elements of the compiler's version number. The major number is the first element of the period-delimited version number and the minor number is the second element. For example, if the version number of the Microsoft C/C++ compiler is 17.00.51106.1, the _MSC_VER macro evaluates to 1700. Enter cl /? at the command line to view the compiler's version number. This macro is always defined.

Visual Studio 2008 (9.0)	1500
Visual Studio 2010 (10.0)	1600
Visual Studio 2012 (11.0)	1700
Visual Studio 2013 (12.0)	1800
Visual Studio 2015 (14.0)	1900
Visual Studio 2017 RTW (15.0)	1910
Visual Studio 2017 version 15.3	1911
Visual Studio 2017 version 15.5	1912
Visual Studio 2017 version 15.6	1913
Visual Studio 2017 version 15.7	1914
Visual Studio 2017 version 15.8	1915
Visual Studio 2017 version 15.9	1916
Visual Studio 2019 RTW (16.0)	1920
Visual Studio 2019 version 16.1	1921
Visual Studio 2019 version 16.2	1922
Visual Studio 2019 version 16.3	1923
Visual Studio 2019 version 16.4	1924
Visual Studio 2019 version 16.5	1925
Visual Studio 2019 version 16.6	1926
Visual Studio 2019 version 16.7	1927
Visual Studio 2019 version 16.8	1928

To test for compiler releases or updates in a given version of Visual Studio or after, use the >= operator. You can use it in a conditional directive to compare _MSC_VER against that known version. If you have several mutually exclusive versions to compare, order your comparisons in descending order of version number. For example, this code checks for compilers released in Visual Studio 2017 and later. Next, it checks for compilers released in or after Visual Studio 2015. Then it checks for all compilers released before Visual Studio 2015:

```
C++

Copy
#if _MSC_VER >= 1910
// . . .
#elif _MSC_VER >= 1900
// . . .
#else
// . . .
#endif
```
