help with C# if/else challenge

i might be miss understanding the challenge.

The following table describes my room temperature preferences. Print the message from the table when a user enters a number in the corresponding range. For example, if temperature is 21 the code should print "Just right." to the screen. Temperature (°C) Message Less than 21° Too cold! 21° to 22° Just right. Greater than 22° Too hot!

CodeChallenge.cs
string input = Console.ReadLine();
int temperature = int.Parse(input);

if (temperature < 21) {
    System.Console.Write("Too cold!"); }
else (temperture = 21) {
   System.Console.Write("Just right."); } 
else if (temperture > 22){
    System.Console.Write("Too hot!"); }

I think you have the right idea, but a few errors. Here's some hints:

  • an else statement takes no conditional expression
  • an "else if" cannot follow a plain else
  • you spelled "temperture" (missing an "a") in two places
  • you have an assignment operator ("=") where you probably want a comparison ("==")
  • check your conditions, what happens when the temperature is exactly 22?

And a suggestion: if you handle the "too hot" and "too cold" cases first, a plain else could cover everything else.

how do i put 21 & 22 in else?

string input = Console.ReadLine(); int temperature = int.Parse(input);

if (temperature < 21) { System.Console.Write("Too cold!"); } else if (temperature > 22) { System.Console.Write("Too hot!"); } else (temperature == 21) { System.Console.Write("Just right."); }

Remember, a plain else takes no conditional expression.

It doesn't need one since it handles all conditions not already covered by the previous if and else if statements.

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 { Console.WriteLine("Too hot!"); }
