What does return zero mean by agreement?

Question

This is probably a stupid question, but I always wonder what is the standard.

In most (not all) of the first C ++ examples, you can see that the main function returns 0. Does this mean that the operation went well or not?

• 0 → OK
• 1 → None.
• Other →?

What is the standard way to do this?

By the way, is it better to return an integer or a logical number in this case?

Thanks guys!
