C# C# Basics (Retired) Perfect Variable Scope

Not sure what the program is specifically looking for in the code...

I've assigned output as a string and also tried using 'string output = (Console.WriteLine);' but this code still gives an error. I'm not sure where to go from here.

Program.cs
using System;

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

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

          Console.WriteLine(output);
        }
    }
}

Your current solution is telling the program to print "You entered [input]." and to print the empty string "output" (it is empty since you did not assign it a default value like you did with the string "input"). Currently, if the user does not enter "quit", the output variable is not assigned a value and can not be printed properly. To fix this you need to redo your else clause as following:

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

This way the string "output" will now store the variable "You entered [input]." if the user enters anything besides "quit", and the WriteLine function can properly print the string.

I understand now. Thanks for pointing that out for me! :)
