Few Questions are horribly erroneous.

Question

I was completing some of the challenges in HTML and PHP, I found terrible errors in questions, those are extremely frustrating.

Answer 1

Also there can be surprising differences between programming languages:
Latest PHP:
$b = 6;
echo $b*$b--;
Result:30
Latest Visual Studio and C#:
int b = 6;
Console.WriteLine(b*b--);
Result:36

Answer 2

I don't think any Html question is "horribly erroneous" though😂
We've been practicing them for quite a while now.
Still as Michal Straka said, you can use the in-app report feature to report wrong questions/answers.

Answer 3

You can report wrong answers or wrong questions. Click 'VIEW CORRECT ANSWERS' after finishing a challenge. Then there is always a small icon on the right at the top. Click it and you can report different types of errors:

Spelling Errors
Wrong Question
Wrong Answer
Off Topis
Other

Keep in mind to test the answer before reporting it. The results can be sometimes surprising.

Answer 4

Got'ya

Answer 5

Yes, I was using an extended conceit for that, but there were errors, I reported them, as implied.
