It seems weird to exit() here instead of simply returning a value...

Why? Within the main() function, "exit(EXIT_SUCCESS)': and
"return EXIT_SUCCESS;" are (almost) exactly equivalent.

Just because it seems odd. It seems cleaner to return
than to exit, but there's no reason for that other than
aesthetics. exit() feels like something that should be
reserved for an error condition.

Ok, so it's a matter of style -- and one on which the authors of the
standard disagree with you, or they wouldn't have included the
EXIT_SUCCESS macro.
