C# C# Basics (Retired) Perfect Variable Scope

Scope rules C#

I don't fully understand what I am meant to be doing here, I understand the scope rules and have attempted to declare the variable outside the if/else under the main method but it still doesn't seem to work.

Program.cs
using System;

namespace Treehouse.CodeChallenges
{
    class Program
    {
        static void Main()
        {  
           string input = Console.ReadLine();
           string output = Console.ReadLine();

            if (input == "quit")
            {
              output = "Goodbye.";
            }
            else
            {
                output = ("You entered " + input + ".";)
            }

            Console.WriteLine(output);
        }
    }
}

Actually, your only problem here is a wrong placement of a semicolon.

          output = ("You entered " + input + ".";)

That semicolon should be outside the brackets, like so:

          output = ("You entered " + input + ".");

Other than that, the scope seems to check out! So keep on working on it!

You have the right idea and you've understood the scope issue correctly. You just need to fix your syntax - there shouldn't be any parentheses in this statement:

output = ("You entered " + input + ".";)

Remove them and you're good to go.
