41,120 PointsA good way to start this challenge is to run the code exactly as it is, then read the error message when it fails to compile. The first error tells you that the name 'input' does not exist in the current scope, so perhaps you need to check that the 'input' variable was properly declared (hint: it isn't!). Hopefully that should get you started. Let me know if you still run into problems.

{
// the scope of these variables are available in the entire class
private string output = string.Empty;
static void Main()
{
// the scope of variables defined here are only available in its method block
string input = Console.ReadLine();
// we can also define string output = string.Empty here
if (input == "quit")
{
// the scope of variables inside if statements, for loops, while loops are only
// available inside them
// string output = "Goodbye." will be only available in this if statement and not
// in its else statement
// so we use the variable defined in this class above or we can define it in the
// method block like string input.
output = "Goodbye.";
}
else
{
output = "You entered " + input + ".";
}
Console.WriteLine(output);
}
}
