C# C# Basics (Retired) Perfect if / else if / else

I can't seem to get past this one error in this C# challenge.

This error message keeps coming up and I have hit a wall.

StudentsCode.cs(17,2): error CS1525: Unexpected symbol `else' Compilation failed: 1 error(s), 0 warnings

I can't see the unexpected symbol it is breaking at.

Hi Marie,

Can you post your code so that we can take a look?

If I had to guess then I'd ask if you have used an 'else' where you needed an 'else if'.

You should post some code. You may have nested the else-statement inside either the if-statement or the else if-statement.

For example:

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

// missing closing bracket
else 
// missing opening bracket

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

The passing code should look similar to the following:

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

Hope this helps!

Interesting code colors there, Jeremy. Try putting "C#" after the three back-ticks indicating the start of the code section.

Yes, I think that's just the default code markup for 3 backticks.

System.Console.Write("Hello World");

Is it c# or cs

System.Console.Write("Hello World");
System.Console.Write("Hello World");

Interesting, it looks like both work :-)

Thank you for your help! It got me successfully past my roadblock. I now realize that when I thought it had attached my code when I submitted my question it actually didn't. For the sake of documentation and closure, here is the error that came up when I had recreated it before applying any community help:

StudentsCode.cs(8,2): error CS1525: Unexpected symbol `else' Compilation failed: 1 error(s), 0 warnings

string input = Console.ReadLine();

  else
  {
    int temperature = int.Parse(input);

    if (temperature <= 21)
    {
      Console.WriteLine("Too cold!");
    }

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

Again, thank you for everyone's help and I will next time be sure to attach my code!

Marie
