Description

Create and exercise a factorial method that has no error checks at all.

Demo Code

using System;//from   w w w.ja v a 2s  .c  o m
public static class MyMathFunctions
{
   public static double Factorial(double value)
   {
      double factorial = 1.0;
      do
      {
         factorial *= value;
         value -= 1.0;
      } while(value > 1);
      return factorial;
   }
}
public class Program
{
   public static void Main(string[] args)
   {
      for (int i = 6; i > -6; i--)
      {
         Console.WriteLine("i = {0}, factorial = {1}", i, MyMathFunctions.Factorial(i));
      }
   }
}
