exception Handling. Its failing in the else

using System;

namespace Treehouse.CodeChallenges { class Program { static void Main() { Console.Write("Enter the number of times to print \"Yay!\": "); string entry=Console.ReadLine(); //Store the number of time in a variable and parse it try { int n= int.Parse(entry);

         if (n<=0)
            { 
           Console.WriteLine("It has to be a positive number"); 
           continue;
            }

           int i=1;

         else
          {

                while (i<=n)

Hi Amit,

It is because your 'int i=1;' is in the wrong place:

using System;

namespace Treehouse.CodeChallenges
{
    class Program
    {
        static void Main()
        {
            Console.Write("Enter the number of times to print \"Yay!\": ");
            string entry = Console.ReadLine();
            try {
                int num = int.Parse(entry);
                if (num<=0) { 
                   Console.WriteLine("It has to be a positive number");
                } else {
                    int i = 1;
                    while (i<=num)
                    {
                        Console.WriteLine("Yay!");
                        i=i+1;
                    }
                    /* // Or use a for loop 
                    for (int i=0; i<num; i++) {
                        Console.WriteLine("Yay!");
                    }
                    */
                }
            } catch(Exception) {
                Console.WriteLine("You must enter a Whole Number");   
            }
        }
    }
}
