I don't understand why it print "Yay" one extra time.

How come it print yay one extra time? When I print 5 it print "yay" 6 times instead if 5 . Is it because the incrementing I in the for loop ? if so how do i fix it ? I dont really understand what the problem is.

Program.cs 
using System;


namespace Treehouse.CodeChallenges 
{
    class Program
    {
        static void Main()

        {
            bool onGooing = true;
            if (onGooing)
            {
                Console.Write("Enter the number of times to print \"Yay!\": ");
                String userInput = Console.ReadLine();/*Get user input */


                int counter = 0; /* count how many time the loop has run */
                int Input = 0;
                try 
                {
                    Input = int.Parse(userInput);/*try it input is an int, if not catch*/

                }
                catch (FormatException)
                {
                    Console.WriteLine("Your input is invalid try again"); /* if the input is everything els than an int*/

                }
                if (Input > 0)
                {

                    for (int i = 0; i <= Input; i ++)
                    {


                        Console.WriteLine("Yay");
                        counter++;
                        continue;




                    }
                }
                else if (Input <0) {
                    Console.WriteLine("Invalid input,you have to input a bigge number then 0");
                }
            }


            /*här avslutas koden*/

        }
    }
}

You are correct. Your mistake is in the for loop.

for (int i = 0; i <= Input; i ++)

Since i = 0 then in case of Input = 5, you actually run the loop 6 times since your logical comparison is <=. If you change it to be just less than (<) then you would print out Yay the correct amount of times.
