Return 0

Question

If you begin with " int main" does the compiler automatically fill in " return 0" at the end? I know it works on sololearn but does it work when you are creating actual programs from scratch?

Answer 1

Yep `return 0` is automatically returned for you if you don't do it. That only works for the main function though.

Answer 2

I don't believe so but maybe this is compiler dependent. E.g. on code playground it seems to work without return.
