quick Question. Can main() function be called recursively. Anything wrong
with calling it recursively ?

Thanks

Recursive `main()' is *not* legal in standard C++.

It is specifically forbidden in C++ (for some reason that's never been
adequately explained to me). But there is nothing wrong with this

int pseudo_main()
{
...
pseudo_main();
}

int main()
{
return pseudo_main();
}

Well, I don't know if this is adequate or even precisely accurate, but
my understanding is that implementations can stick all kinds of
initializations stuff in at the beginning of main(), and if that stuff
were executed more than once the results could be bad.

Of course, I don't see any good reason that an implementation could not
do precisely what you did in your reply. Perhaps this point makes this
explanation inadequate.
