Find factorial of a number in C# using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace FactorialNumber\_ForLoop { class Program { static void Main(string\[\] args) { int number, fact = 1; Console.WriteLine("Enter the number"); number = int.Parse(Console.ReadLine()); for (int i = number; i >=1; i--) { fact = fact \* i; } Console.WriteLine("{0} Factorial is {1}",number,fact); } } } Output: Enter the number 5 5 Factorial is 120

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
