If you're referring to the value after "return", it doesn't matter what you return unless you have another program waiting to receive the exit value of this process. Say, for example, if you had this program return 0 if terminated successfully and 1 if something goes wrong, a separate process could be waiting for this one to finish so it could then do X or Y depending on the successfulness of this process.

That stuff is pretty far down the road though, so basically, you can return any int.
