  • *. h or *. hpp for your C++ headers class definitions
    another convention is to use h for C headers and hpp for C++; a good example would be the boost library Quote from Boost FAQ, File extensions communicate the "type" of the file, both to humans and to computer programs The ' h' extension is used for C header files, and therefore communicates the wrong thing about C++ header files
  • c++ - . c vs . cc vs. . cpp vs . hpp vs . h vs . cxx - Stack Overflow
    * h or * hpp for your class definitions What is the difference between cc and cpp file suffix?
