Return 0; in other languages other than cpp?

Question

what is the difference of return 0; compared to other programming language?

Answer 1

In C and C++ programs the main function is of type int and therefore it should return an integer value. The return value of the main function is considered the "Exit Status" of the application. On most operating systems returning 0 is a success status like saying "The program worked fine."
