Compiler error on the if/else if/else FitnessFrog quiz

Unsure why this won't compile

CodeChallenge.cs 
string input = Console.ReadLine();
int temperature = int.Parse(input);
if (temperature < 21)
{
    Console.WriteLine("Too cold");
}
else if (temperature >21)
{
    Console.WriteLine("Just right.");
} 
else (temperature >22)
{
    Console.WriteLine("Too hot!");
}

Hey Bryan,

There's a few things here.

  1. You are missing an ! mark for "Too Cold!" (Challenges are very picky)
  2. The else part cannot have a condition attached to it. The else clause only runs when everything else (the if and/or the else if) have failed.
  3. The else if isn't checking for the right condition. The way it is now, any temperature over 21 will pass (but the challenge only wants 21 or 22). So here you need to use == and OR.

I've included the code below for you to review. I hope it makes sense. :)

string input = Console.ReadLine();
int temperature = int.Parse(input);
if (temperature < 21)
{
    Console.WriteLine("Too cold!");
}
else if (temperature == 21 || temperature == 22)
{
    Console.WriteLine("Just right.");
} 
else
{
    Console.WriteLine("Too hot!");
}

:dizzy:
