Create a function to calculate the factorial of a given number using recursion.

Question

Aryan Kumar · Answer

Sure, here is the C# code to create a function to calculate the factorial of a given number using recursion:
C#
using System;
public class Factorial
{
    public static int Factorial(int number)
    {
        if (number == 0)
        {
            return 1;
        }
        else
        {
            return number * Factorial(number - 1);
        }
    }
    public static void Main(string[] args)
    {
        int number = Convert.ToInt32(Console.ReadLine());
        int factorial = Factorial(number);
        Console.WriteLine("{0}! = {1}", number, factorial);
    }
}
This function first checks if the given number is equal to 0. If it is, then the function returns 1. Otherwise, the function returns the product of the given number and the factorial of the number minus 1. The Main() method then reads a number from the user and calls the Factorial() function to calculate the factorial of the number. The result is then printed to the console.
