Question

Vote below or answer please, who downvoted (or would downvote) the following submission for a quiz:

//Declined due to community downvotes. Please review
What is the output of this code?

System.Console.Write('0' + '0');

☐ 00
☐ Some compilation error
☐ Empty string
☑ 96

Answer 1

@Alx vSeti You are right! Knowing the answer apriori made me overlook the possible solutions offered. It is actually a very good formulated quizz!
Possibility of discussion like this, should be in the qiz factory below every submission.
A good, constructive, and educational debate could be used as a definitive way to rate submissions.
Send an email to SL explaining your reasons: I hope they'll approve it.

Answer 2

Interesting, why 96? (I know nothing about C#)

Answer 3

So perhaps the people who were rating the quiz also expected the answer to be "00" and thought the question was too easy (or wrong if they actually tried to answer)

I guess that's the problem with counter-intuitive questions..

Answer 4

@Alx
I wouldn't downvote it, for me it would be a pleasure to have such questions. But I can understand that the decision is made by the community. This is not covered by the courses, I know a lot of approved questions aren't covered by the courses, but still: Course content and challenges should go together.

Answer 5

Probably not everybody knows that '0' corresponds to 48. The question implies knowledge of the ascii table. I know that 0 as A or a are common "delimiters" but how would you feel if you face a question asking you the int associated to '#x27;?
And even if you go searching for it, and you find it, will you upvote that question?
Honestly I think there are worse questions that got approved, but that is another discussion for another time.

Answer 6

I think it's a bit to tricky. May be confusing. But actually it's a good question.

Answer 7

Nice question. I myself forgot a lot about C++ and learned about the same (amount) of Javascript last years, so I thought it would be 00 (never knew enough of C#). So yes it's tricky, but not useless (as you wrote, very nice example given) and I like it. So crowd "expertise" (or "review", sorry if i misspelled some words) is bad sometimes (I'm not wondering why).

Answer 8

@Michael, because '0' as a symbol is coded by a number 48. Before, I was expecting, that C# is smarter than C++, and the result would be a string "00".

Answer 9

Too tricky and usless

Answer 10

As you can see I'm not very familiar with the quizz factory. I think downvotes are deserved only in case of mistakes, erratic/ambigous content.

Answer 11

@seamiki The quiz does not imply knowing that ‘0’ corresponds exactly to 48. Just that ‘0’ is not 0 (and many know that 0 is reserved for the end)

Answer 12

Sometimes when the reviewers don't know the answer, they downvote out of ignorance.

Answer 13

96!... Because you are adding char and not string and the result cannot be a string

Answer 14

@Alx vSeti I didn't come across your question as i'm not very active in quiz submission and rating, but even if I did, I had no reason to like it, as I explained in my previous post. I think your question is better than others approved but that doesn't automatically make it a question I'd like.

Answer 15

Concerning "useless". This example is from my programming practice (not '0'+'0' of course). First I needed only 1 symbol in some output. So char was used. Later I needed additional symbol for some output, so I just added c+'!'. The result was unexpected. In some circumstances the modifications to a program could be released without testing.

Answer 16

Resubmitted the quiz with some corrections in accordance with your comments and critics.

Thanks to everybody!

Answer 17

I upvoted (would upvote) this quiz

Answer 18

@seamiki, Tashi N, Frost, Rrestoring faith, so would you downvote the question?
Or is it just assumption of downvoters' motivation?

Answer 19

@seamiki, Frost, the question was about downvoting. Because if you feel indifferent to a quiz, you can just skip.

Answer 20

Wrong answer
