What type of quizzes should be created in the Quiz Factory so that they get approved?

Question

I always get my quizzes declined due to downvotes... So what type of questions do the people want?
When I create simple questions, they are declined with the reason - Too Simple or Many such questions exist...
And when I create a little difficult questions, they are declined with the reason - Too Complex or Declined due to community downvotes...
Is there a particular type of questions that are accepted no matter what?
Eg: This Q was declined due to downvotes. Why? Whats wrong in this?

Answer 1

Yes. They seem to like post/pre increment/decrement and pointer arithmetic because they are hard to duplicate if you have some imagination. I got 4 approved that were like that and a bunch declined because they were probably too hard or already been proposed.

Answer 2

@Kinshuk Good to know, thank you!

Answer 3

@Kinshuk, sorry, not an answer but a question, how long did it take you to have your submissions declined? Because 3 weeks ago I submitted 25 questions for HTML and they're still pending :(

Answer 4

Select only the valid namespaces :
// C++ Question, the rules of naming namespaces are the same as variable naming
1) namespace 2foo{}
2) namespace std{}
3) namespace ^12&{}
4) namespace GLIBCXX_0XXX{}

Answer 5

@Paola Mancia
The news of declination was given to me 3-4 weeks after posting the question...

Answer 6

@Paola Mancia
You're welcome...

Answer 7

@Alx vSeti
Why not?
And people may get it wrong...
And btw, completing a code to print 5 by using 12-7 is not such a difficult question (and its even approved)...

Answer 8

@Alx vSeti
Those two are the incorrect answers...
And yes, though they may not be such a great deal, 12-7=5 isn't a great question either..

Answer 9

@Alx vSeti
Thats what people must realize that the rules of naming namespaces are the same as naming of variables.
And tell me, why are there so many approved questions on naming of variables, telling the valid data types, etc?
And if my question is way too easy, why don't they approve my difficult ones?
(They declined them with the reasons - Too specific or similar questions exist..., but I have never seen such questions that I uploaded...)

Answer 10

@Kinshuk Vasisht, I don't know why they declined your difficult quizzes. If you would show them to the community, I could say my personal opinion about a question.
For me a good question is one revealing me a new concept, showing me a process under the hood, or saving me from unobvious errors. In C++ I see the lack of questions about STL.

Answer 11

@Kinshuk Vasisht, you could use "2foo" or "^12&" names in your code? Me - not. And even if somebody could, then the error was automatically detected by a compiler.
For me, it is not strange, that the rules of naming namespaces are the same as naming of variables.

Answer 12

@Kinshuk Vasisht, are other simple arithmetic or naming questions still being approved for C++?

Answer 13

I did not come across with this submission, but I could skip it as too easy or upvote for the purpose of slight diversity of similar questions.

Answer 14

Would anybody want to use names for namespaces like
^12&
2foo
?
Or could hardly detect such an error?
If not, maybe there is no sense in this quiz?
