Apart from what lh_mouse says about C++, in C if your function is
declared to return an int and there is no return statement the returned
value is undefined (not to be confused with undefined behavior, which
only happens on this case if you *use* the value returned by that
function.)
So you can omit the return at the end of `main' on your toy C program
unless you plan to use the process' exit value.
