Not sure what if Im solving it right. I do keep getting an error about the catch whenever I put anything in there.
using System;
namespace Treehouse.CodeChallenges
{
class Program
{
static void Main()
{
try
{
input = Console.ReadLine();
if (input == "quit")
{
string output = "Goodbye.";
}
else
{
string output = "You entered " + input + ".";
}
}
catch()
{
}
Console.WriteLine(output);
}
}
}

18,267 PointsThere are a few problems:
First, you don't need the "()" after catch, just the word catch by itself
try
{
// do something
}
catch
{
// do something (or nothing!)
}
(Note, the parentheses are used if catching something specific like catch (System.Exception) {}
But you'll still have some other problems:
- You never initialized input (you need: var input = Console.ReadLine())
- Because of above, when the code got to this line of the try block, it will fail and go to catch
- You can't use output after the try/catch block, because it won't be defined if try fails (i.e. move Console.WriteLine(output) to the inside of the try block)
Try again with that info. I don't want to give you the full answer if that will get you what you need. Comment back if you need any more help!
