• constexpr not compiling in VC2013 3 answers

I have got myself a copy of VS 2013 professional and I've been quite happy with this IDE, however one down side that have been annoying me for a while is that some features that I can easily use with g++ such as vector<string> s{ "a", "b", "c", "d" }; and constexpr won't compile with VS compiler. I think it has something to do with VS not using c++1x? Can someone please tell me how to add these features to VS?
