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:
[php]
5!=5*4*3*2*1=120
7!=7*6*5*4*3*2*1=5040
[/php]
The factorial is generally used in Combinations and Permutations (mathematics).
Let’s see the Factorial program in VB.NET using for loop.
[php]
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
[/php]
Output
