**Factorial Program in VB.NET: **

Factorial, in mathematics, the product of all positive integers less than or equal to a given positive integer and denoted by that integer and an exclamation point. Thus, factorial seven is written 7!, meaning 1 × 2 × 3 × 4 × 5 × 6 × 7.

Factorial of n is the product of all positive descending integers. Factorial of n is denoted by n!. For example:

5!=5*4*3*2*1=120

7!=7*6*5*4*3*2*1=5040

The factorial is generally used in Combinations and Permutations (mathematics).

Let’s see the Factorial program in VB.NET using for loop.

Imports System

Module Program

Sub Main(args As String())

Dim i, number As Integer, fact As Integer = 1

Console.Write(“Enter any Number: “)

number = Integer.Parse(Console.ReadLine())

For i = 1 To number

fact = fact * i

Next

Console.Write(“Factorial of ” & number & ” is: ” & fact)

Console.ReadLine()

End Sub

End Module
