1,485 Pointstry{} and catch(FormatException){} placement
I can't figure out where to put the try{} and catch(FormatException){}.
using System;
namespace Treehouse.CodeChallenges
{
class Program
{
static void Main()
{
//Create a tracking variable that is set to zero
var tracking = 0;
//Prompt user to enter a number
Console.Write("Enter the number of times to print \"Yay!\": ");
//store entry in a variable
var entry = Console.ReadLine();
while(true) //Repeat the print
{
try
{
//Convert variable to an integer
var repeats = int.Parse(entry);
if (tracking >= repeats) //if the tracking varialbe is >= entry variable, break the loop
{
break;
}
//Print Yay to the screen and add 1 to tracking variable
Console.WriteLine("\"Yay!\"");
tracking += 1;
}
catch(FormatException)
{
Console.WriteLine("You must enter a whole number.");
continue;
}
}
}
}
}

231,248 PointsThe try looks good but the exception should exit the loop instead of continuing it. That would cause it to get stuck in the loop, printing the error message over and over.
Also, while not essential to passing the challenge, it might make more sense to do the numeric conversion just once, before the loop starts.
