You should use "if...else if...else" pattern. So your code should be like below:

string input = Console.ReadLine();
int temperature = int.Parse(input);
if (temperature < 21)
{
  Console.Write("Too cold!");
}
else if(temperature >= 21)
{
  Console.Write("just right.");
}
else
{
  Console.Write("Too hot!");
}

However, i guess the logic should be like this:

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

I hope it will be helpful.

it should be <= 22 since the question ask for 21-22 to be just right.

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