C# C# Basics (Retired) Perfect Variable Scope

Not sure how to make sure input variable is defined correctly.

Not sure where I am going wrong here.

Program.cs
using System;

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

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

Input needs to be defined as something. Define it as a var.

var input = Console.ReadLine();

Also remember to define output outside the if condition.

Thank you Mr. Severude, I defined input as a var and the code ran successfully.
