is it possible to get the source code for standard c++ library?

The GNU project is Free and Open Source software, and contains an implementation of the C++ standard library.
You should already have the sources in your compiler installation. If you are using an IDE with a "jump to include file" command, select any STL header and jump to it. If you are using some kind of UNIX, look in /usr/include/c++. See where that STL header includes other headers and recurse :v) .
If you have Visual Studio Professional, it has source code in
X:\Microsoft Visual Studio 9.0\VC\crt\src
For Win10x64 with VS2017 default install paths,the source code are here:
part1:VCRuntime,which include code that will change for every version of Visual Studio,it contains function like the CRT entry point "mainCRTStartup",the code are here:
C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\VC\Tools\MSVC\14.16.27023\crt\src
part2:C standard library,which include code that is stable over generations of Visual Studio,like the function fopen,and it also contains stable CRT functions like _initterm,the code are here:
C:\Program Files (x86)\Windows Kits\10\Source\10.0.17763.0\ucrt
i.e. this part has been moved to Windows SDK,distributed with Windows instead of Visual Studio.
