Find factorial of a number in C# using recursion

    using System;
    using System.Collections.Generic;
    using System.Linq;
    using System.Text;
    using System.Threading.Tasks;

    namespace FactorialNumber\_Recursion
    {
        class Program
        {
            static void Main(string\[\] args)
            {
                int number =0;

                Console.WriteLine("Enter the number");
                number = int.Parse(Console.ReadLine());
                int fact = Factorial(number);
                Console.WriteLine("{0} Factorial is {1}", number, fact);
            }

            public static int Factorial(int num)
            {
                if (num ==0)
                {
                    return 1;
                }
                else
                {
                    return (num \* Factorial(num - 1));
                }
            }
        }
    }

Output: Enter the number 5 5 Factorial is 120
