Idk what you're doing but the C++ version works fine.

Yep, does not compile whatever...:

        Assert::That(DetermineBase(log), EqualsWithDelta(M_E, 1e-12));

Fixed.

I've edited how k was generated, it should be fixed now for both C and C++. Mark as resolved if it is.

k should be less than n because the balls are numbered from 0 to n - 1.
C++ has also the same problem.

@danderle ..

• That's what i've bet , Unfortunately
• The C Translator has been inactive for pretty long time , I've mentioned him 1 month ago Check Here, also (You can see Below , another issue raised concerning C Translation hasn't been resolved Yet )
• So if you could translate it into C Language and Leave me a link with it so i can approve and overwrite the current bugged one I'll be grateful .. Tuned .. Regards .. Zizou

@danderle ..

• Well , thanks Bro for pointing out , I Think You've attempt the kata either in C or C++ but the odd thing is Both of them has been completed 16 and 42 Times Without an issue raised
• So for more help , Could you please name the language that you've attempt in letting me mention its translatoe to fix the problem
• I'm tuned to hear your feedback .. Hope you all the best .. Regards .. Zizou

Changed the comment in the initial code, now it says:

/* Please make sure you report the count of elements in the memory pointed to by pResultCount,
   even if the result might be {"None"}. */

?

You need to return an array of elements, where is the memory for that array allocated?

The problem is with the optional parameter. He/she hasn't defined it in the function.

25 people solved it in c++, any clue what the problem might be now?
