When I put other number than 0 the program successful but in the course they say that the program can't matter if you put other0

I think to return value.

It doesn't matter what the return value is, because it won't be used. But, it definitely should be an integer

On Unix systems (where C comes from), the return value is used extensively. For example, if a script uses your Program A to extract some data, and program B to modify it, if the program A returns a non-zero value, the script will not run program B, because there is no data for it to use. On Windows, the return value is generally ignored.
