"return n" is technically correct, and is slightly more satisfactory
from a "top-down control" viewpoint.  I have heard that there are
some purported C implementations that ignore the return value
from main(), though, always returning a success indicator unless
exit() is used.  Those aren't Standard-conforming implementations,
but you might be stuck with one.

P.S.  You don't need parentheses around the return expression.
