C# Program To User-Define Factorial Number

In this blog, you will learn how to use C# programming Language to user-define a Factorial Number.

Introduction 

 

In this blog, we will write a C# program to user-define a factorial number.

 

User-Define Factorial number in C#

 

This code sample shows you how to user-define a factorial number in C#:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace UserDefineFactorialNumber {
    class Program {
        static void Main(string[] args) {
            int a = 1, Fact = 1;
            int Num = 5;
            while (a <= Num) {
                Fact = Fact * a;
                a++;
                Console.WriteLine("The Factorial Number is " + Fact);
            }
            Console.ReadLine();
        }
    }
}
