Write a Program to find the factorial of a given number

Factorials: In this program we are going to be print factorial of a given number. Factorial is represented using '!', so five factorial will be written as (5!), n factorial as (n!).

 Also n! = n*(n-1)*(n-2)*(n-3)...3.2.1 and zero factorial is defined as one i.e. 0! = 1.

This program takes an integer from a user. If user enters negative integer, this program will display error message and if user enters non-negative integer, this program will display the factorial of that number.

For example user input is 5 then the factorial of a given number is (1*2*3*4*5) =120

VB Script program will be as shown:-
