Compiler Error, Unexpected Symbol??

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 if(temperature <= 22) {Console.WriteLine("Just right.");} else(temperature > 22) {Console.WriteLine("Too hot!");}

with this code I am getting this error: StudentsCode.cs(13,23): error CS1525: Unexpected symbol `{' StudentsCode.cs(13,24): warning CS0642: Possible mistaken empty statement

Last time I checked there isn't 13 lines of code

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 if(temperature <= 22) {Console.WriteLine("Just right.");}
else(temperature > 22) {Console.WriteLine("Too hot!");}

The line number offset is probably due to some code that the challenge adds.

But the issue is that a plain "else" doesn't take a conditional expression. It doesn't need one since it handles all cases not already covered by the previous "if" and "else if" chain.

You'll also need to modify your tests, because when you check for greater or equal to 21, all remaining values will be covered and considered "just right" (even if they are "too hot").
