Dont just quote half of the answer...

For the second question, no one said anything about globally mentioning them, what you see on this thread is pieces of codes to make people think, it ain't a whole program, there ain't no includes, no main, no output and no nothing, again, it's just pieces of code. Now, if I ever wanted to use these then I would probably store them both in a structure and keep it global or pass its address to other functions.
