return value?

i'm sorry to double post, but the void main is locked...

I understand that void main is wrong, but is there a problem with simple functions that don't return a value, is it ok or should i always return a value?


thank you.

No, no problem. You define the signatures of functions other than main, so you can make them what you like.
