having trouble with try/catch, any help is appreciated! thank you.
using System;
namespace Treehouse.CodeChallenges
{
class Program
{
static void Main()
try
{
{
Console.Write("Enter the number of times to print \"Yay!\": ");
string input = Console.ReadLine();
catch()
{
Console.WriteLine("You must enter a whole number.");
}
int count = int.Parse(input);
int i = 0;
while(i < count)
{
i += 1;
Console.WriteLine("Yay!");
}
}
}
}
}

Also, while it's not a technical issue, you might want to remove that extra set of nested braces to improve readability.

try { The code inside these blocks }
catch { The error if the code inside the try blocks couldn't run. }
