## C# Sharp Recursion: Exercise-9 with Solution

Write a program in C# Sharp to find the factorial of a given number using recursion.

Pictorial Presentation:

Sample Solution:

C# Sharp Code:

``````using System;

class RecExercise9
{
static void Main(string[] args)
{
Console.WriteLine("\n\n Recursion : Find the factorial of a given number :");
Console.WriteLine("-------------------------------------------------------");

Console.Write(" Input any positive number : ");
long fact = FactorialCalcu(n1);
Console.WriteLine(" The factorial of {0} is : {1} ", n1, fact);
}

private static long FactorialCalcu(int n1)
{
if (n1 == 0)
{
return 1;
}
return n1 * FactorialCalcu(n1-1);
}
}
```
```

Sample Output:

``` Recursion : Find the factorial of a given number :
-------------------------------------------------------
Input any positive number : 8
The factorial of 8 is : 40320
```
