Factorial program using recursion in c#

We have come across the situations where a function calls another function but there is one more possibility that a function calls itself.

When a function calls itself it is known as recursion. It is usually used where we have to repeat a process again and again.

The following program for finding factorial using recursion is an example of recursive function and its implementation.

1. using System;    
2.     
3. namespace Recursion_Example   
4. {    
5.     class Program    
6.     {    
7.         static void Main(string[] args)    
8.         {    
9.            int n;
10.             Console.WriteLine("Enter the Number");    
11.     
12.                
13.              n =Convert.ToInt32(Console.ReadLine());     //read number from user
14.     
15.             double factorial = Factorial(n);    //invoke the static method    
16.     
17.             //print the factorial result    
18.             Console.WriteLine("factorial of"+n+"="+factorial.ToString());    
19.     
20.         }    
21.         public static double Factorial(int n)    
22.         {    
23.             if (n == 0)    
24.                 return 1;    
25.             return n * Factorial(n-1);//Recursive call    
26.     
27.         }    
28.     }    
29. }

C# Programming Structure

Classes in C#

C# classes are the primary building blocks of the language.C#  also provides some predefined set of classes and methods.These classes and Methods Provides various basis functionalities that you may want to implement in your Application.
Creating  First "Hello World" Program
Using System;
public class Hello
{
public static void Main(string []args)
{
         
Console.WriteLine("Hello,World!! \n");
            Console.ReadLine();
}
}

Let us look at the various parts of the given Program:
 The First Line of program using System; the using keyword is used to includes the System  namespace in the program.A program has multiple using statements.
