Note: If you are new to C# and Console Application. Try to code First C# Program

Note: Read articles on how to use Loops and Conditions.

Let’s find out a simple and easy way to code the program.

Practical Implementation:

using System;

namespace patternProblem.Simple_program
{
    class Simple10   //factorial of a number
    {
        static void Main(string[] args)
        {
            Console.Write("Enter a number: ");
            int n = Convert.ToInt32(Console.ReadLine());
            int factorial = 1;
           
            if (n >= 0)
            {
                for (int i = n; i > 1; i--)
                {
                    factorial = factorial * i;
                }
                Console.WriteLine("Factorial of {0} is: {1}", n, factorial);
            }
            else
            {
                Console.WriteLine("Factorial is -ve number is not possible");
            }
            Console.ReadKey();
        }
    }
}

Output:
The input number is 5. The program will do find factorial of the input operator. The output is shown below:

Enter a number: 5
Factorial of 5 is: 120
