Non-Compilation

My code compiles in Visual Studio, but I get bummer here

using System;

namespace Temerature { class Program { static void Main() { string input = Console.ReadLine(); int temperature = int.Parse(input);

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

}

CodeChallenge.cs
using System;

namespace Temerature
{
    class Program
    {
        static void Main()
        {
            string input = Console.ReadLine();
            int temperature = int.Parse(input);


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

Hi there, Michael Bragg! First, and foremost, these challenges generally require that you not do anything they haven't asked for. In your code, you've included all the code that was necessary to compile your program. This includes the directive to use System, a namespace, and even a main function. That is already set up for you in the challenge. All it wants you to do is enter the small code snippet it's asking for. The code it's looking for is between the line with string input and the end of the else statement.

Once you put that code into the challenge, you will still get a Bummer! message. There's a small logic flaw in else if statement. It should print out "Just right." if the temperature is 22.

Hope this helps! :sparkles:

            System.Consolte.WriteLine("Too hot!");
            }

Still get the bummer error

Hi again! Now you have some syntax errors. Because you've included your temperature < 21 in quotation marks, it is now a string instead of an expression. You will need to remove the quotation marks there. You also have a stray quotation mark in your else if statement. The code should print out "Just right" if the temperature is 21 or 22.

       Not a string any longer and still bummer

Spamming this thread will not make anyone more inclined to give you an explicit answer. Again, the code should print out "Just right" if the temperature is 21. It should also print out "Just right" if the temperature is 22. Either one of those temperatures fall in the "Just right" range.

Please read what I have written repeatedly. Your code currently prints out "Just right." when the temperature is 22. It should also print out "Just right." when the temperature is 21. What does your code currently print out when the temperature is 21? It prints out "Too hot!".

How am I spamming posting my code Jennifer?

Personally, I feel like posting within a few seconds of each other while completely disregarding what was written back to you several posts up could be considered spamming.

The last piece of code that you posted contains this: else if(temperature == 22);.

But again, the code should print out "Just right." if the temperature is 22 or 21. Either one. But currently, your code only prints out "Just right." when it's 22.

I have corrected what you suggested:

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

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

Ok now it's correct except for one semicolon. You've placed an extra semicolon at the end of the expression in the else if. Removing that will cause it to pass.

...html <p> string input = Console.ReadLine(); int temperature = int.Parse(input);

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

This is my current code and still Bummer

Again, you have an extra semicolon at the end of the expression in the else if that is causing a syntax error. Removing that will cause the challenge to pass.
