I'm running through the tutorials for c programming on this site, and have noticed an inconsistency in the examples, that haven't been explained (at least thus far in the tutorials, I'm on chapter 6 right now). In the first chapter or so, I'm told that the main() function should have "return 0" at the end of it. Then, after a couple examples, at least to chapter 6, you don't see return 0; at the bottom of the main() function in the examples anymore.
Is this a do as I say, not as I do, is it just not necessary, or has it been assumed that I will plug this in when I do the example, or create my own code?
Thanks for any assistance!
