This kind of way is simple, if you study programming languages. It is right not to say or explain all the details in doing this cause its difficult and long to explain, if one does not know how to use compilers, better study or research first. There are many compilers, so don't ask to much. Try to know the different compilers first so that you could relate to this.
BTW he said use "c++" <- use devc++ as a compiler.
