    ...no. Once you return, your function is done. return() does just that - it returns the execution flow back to the calling function.

    You do not fclose() at all. That's the calling function's job.

    OK this is strange, you are using all C in your project.
    Are you supposed to do that? This is C++, so...
    You are reading with scanf in a very unsafe way, but you could easily fix that by using the "correct" C++ model instead.
    Or are you going to keep on using C? I'm wondering here...

    Outside of your DOS world, your header file is meaningless.
