I moved from DevC++ to Codeblocks and I've come up with this code when I added a header file.
In DevC++, I'm just including the file by using #include "Engine.h". I searched in google and still I didn't understand it. I have an Engine class in Engine.h and the functions in Engine.cpp. Can anyone explain this to me.Code://Engine.h #ifndef ENGINE_H_INCLUDED #define ENGINE_H_INCLUDED #endif // ENGINE_H_INCLUDED
