Introduction
I have used Visual Studio 2012 for debugging purpose. But you can use any version of visul studio as per your availability..
Write a C# program to create a recursive function to find the factorial of a given number
using System;
class functionexcercise
{
static void Main()
{
decimal fact;
Console.Write("Enter a number : ");
int num = Convert.ToInt32(Console.ReadLine());
fact = Factorial(num);
Console.WriteLine("The factorial of number {0} is {1}", num, fact);
Console.ReadLine();
}
static decimal Factorial(int n1)
{
// The bottom of the recursion
if (n1 == 0)
{
return 1;
}
// Recursive call: the method calls itself
else
{
return n1 * Factorial(n1 - 1);
}
}
}
Result
