1,653 PointsWhy Does Input Not Exist
Hi I am stuck and don't understand why input dies not exist in the context. Please tell me what is wrong with this code.
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 + ".";
}
}
}
}

- You need to put the word "string" in front of the variable declaration of
input. -
Console.WriteLine(output)should be also in theelsestatement.
If you accomplish those, you should end up as:
using System;
namespace Treehouse.CodeChallenges
{
class Program
{
static void Main()
{
string input = Console.ReadLine();
if (input == "quit")
{
string output = "Goodbye.";
Console.WriteLine(output);
}
else
{
string output = "You entered " + input + ".";
Console.WriteLine(output);
}
}
}
}

or
string input = ...
Alexander Davison
65,469 PointsDid you try the challenge with just doing that?
It still causes an error that way, because you also need to add the Console.WriteLine() part inside the else statement :)

18,323 PointsHey Alexander I didn't actually attempt the challenge. I only answered regarding "Input".
Good call on the other error :)
It could also be solved by just declaring "var output = string.Empty;" just below or above "var input = ..." then the Console.WriteLine() can remain outside of the "if" conditions, but more than one way to skin a cat

65,469 PointsYeah.
