Hidden Features of C++? [closed]

Answer 1

One language feature that I consider to be somewhat hidden, because I had never heard about it throughout my entire time in school, is the namespace alias. It wasn't brought to my attention until I ran into examples of it in the boost documentation. Of course, now that I know about it you can find it in any standard C++ reference.

namespace fs = boost::filesystem;

fs::path myPath( strPath, fs::native );
