I have installed visual studio code, and I want to use it to build my C++ projects on Windows, so I need download MinGW-w64. But before doing that, I need know if the MinGW-w64 supports C++14?
Simply download it and try, it does not hurt your computer at all.
As said in MingGw-w64 website, "a pthreads library for C++11 threading support and simple integration with existing project."
