Question
Hi,

This is kind of an odd q.
do you know why the void should be written in the declaration of main ?
(of course "int main() will also work, but it seems more corect to write "int main(void)" do you know why ?

Thanks,
motty.  

Answer
According to ANSI standards, it is int main().
The reason for this is, main() function has to return an integer value as status to the calling program.
In the calling program, it would have been called like this:
int status = main();

So, if you define main() to return void, then the calling program will have problem!
