return 0;

Question

hi i cannot understand why they add return 0; to methods which they return nothing ! is this return 0; important or i don't need to use it anymore ?

Answer 1

If you have a int main() routine you can return 0 to see that no error happened during the process

Answer 2

Supriya Gangapatnam Then you need to use "return;" not to end when the main function ends, i.e. when you want to stop it manually

Answer 3

Supriya Gangapatnam In any function returning void you can use return; to end the function. Thats just what i meant to say.
