/* Recursive factorial function programmed by Arjang
For more info email me arjang7@hotmail.com
a recursive function is a function that will call itself
it is probably the most difficult type of function designing
but when you get use to it, you'll find it VERY USEFULL
the c version of this function is also available right here.
