Seeing that you have completed C++ course I suggest you to review chapter about pointer.

Answer 3

Well, thanks for your suggestion. I will be happy enough if you explain it to me instead of suggesting something.

Answer 4

I assume you are a relative beginner....so.... this is a basic swap routine that might help you understand "pass-by-value" and "pass-by-reference" in "C".
Just to add......understanding pointers is a "must", particularly in "C" programming.
