Cannot make it work the way it was asked

using System;

namespace Treehouse.CodeChallenges
{
    class Program
    {
        static void Main()
        {
    int counter = 0;
       Console.Write("Enter the number of times to print \"Yay!\": ");
       string yaynumber = Console.ReadLine();
       string yay = "Yay!";

        counter = int.Parse(yaynumber);
       for (int i = 0; i <= counter; i++)
       {
           Console.WriteLine(yay[i].ToString());
       }

       Console.ReadLine();
        }
    }

You got very close, but you did something odd with your string by applying an index ([i]) that would pick out a single character at a time. It would also cause errors when printing more than 4 lines, since you run out characters in your word. Plus, you also have a stray extra ReadLine after the loop.

See the comments in the corrected code below:

namespace Treehouse.CodeChallenges
{
    class Program
    {
        static void Main()
        {
            int counter = 0;
            Console.Write("Enter the number of times to print \"Yay!\": ");
            string yaynumber = Console.ReadLine();
            string yay = "Yay!";

            counter = int.Parse(yaynumber);
            for (int i = 0; i <= counter; i++)
            {
//              Console.WriteLine(yay[i].ToString()); <-- this prints just one letter of the word
                Console.WriteLine(yay);;               // this prints the whole word
            }

//          Console.ReadLine();                       <-- this waits for input that is not used
        }
    }
}

Thanks Steven,

using System;

namespace Treehouse.CodeChallenges { class Program { static void Main() { int counter = 1; Console.Write("Enter the number of times to print \"Yay!\": "); string yaynumber = Console.ReadLine(); var yay = "Yay!";

    var counter1 = int.Parse(yaynumber);
   for (int i = 0; i <= counter; i++)
   {
       Console.WriteLine(yay);
       if (counter1 <= counter)
       {
           break;
       }
       else if (counter1 <= 1)
       {
           Console.WriteLine("please enter valid number");
       }
       counter += 1;

       continue;


   }


    }
}

}

This code work perfect if i want to print yay. But it will still print if i enter 0 or -numbers. And it will not continue.

Remember to choose a "best answer". :)

And I was a bit confused by your last comment. Did you mean for that to be a new question?

I tried to toString() already but it did not work.

this code worked but as i typed 0 its still printing one.

using System;

namespace Treehouse.CodeChallenges { class Program { static void Main() { int counter = 1; Console.Write("Enter the number of times to print \"Yay!\": "); string yaynumber = Console.ReadLine(); var yay = "Yay!";

    var counter1 = int.Parse(yaynumber);
   for (int i = 0; i <= counter; i++)
   {
       Console.WriteLine(yay);
       if (counter1 <= counter)
       {
           break;
       }
       else if (counter1 <= 1)
       {
           Console.WriteLine("please enter valid number");
       }
       counter += 1;

       continue;


   }


    }
}

}

After trying again and again. I got this right.

using System;

namespace Treehouse.CodeChallenges { class Program { static void Main() { int counter = 0; Console.Write("Enter the number of times to print \"Yay!\": "); string yaynumber = Console.ReadLine(); var yay = "Yay!";

        try{
            var counter1 = int.Parse(yaynumber);
    while (counter1 <= 0)
    {

        Console.WriteLine("You must enter a positive number.");
        break;
        }
   for (int i = 0; i <= counter; i++)
   {

       if (counter1 <= counter)
       {

           continue;
       }
       Console.WriteLine(yay.ToString());
       counter += 1;

       continue;


   }
        }
            catch(FormatException){
            Console.WriteLine("You must enter a whole number.");
            }

   Console.ReadLine();

    }
}

}
