Return does not exit a program.  A return statement denotes a point in a 
function when the function will stop executing and the specified value 
will be returned to the calling function.
In C++, a return in your main function will cause the program to stop 
executing, because there was no calling function to give control back to.

There probably won't be a whole tutorial on a 'return' statement - it's 
a fundamental part of functions and you should've picked up on it in any 
tutorial discussing how to define functions.

This is not a good thing.  You shouldn't have a function that is this 
long.  The entire point of functions is small snippets of reusable code 
- having one massive function do everything negates the whole benefit of 
functions.  You may just as well have not put it in a function at all.
Where is this code, by the way?  I didn't receive a copy of it.
