the standard term is "Variably Modified types", and yes they are distinct from VLAs, only the VM types will be mandatory in C23, the VLAs are still optional

Is this really called "VLA declaration"? I always thought that "VLA" is used only to refer to stack allocated arrays with runtime decided size.

no, your prototype is worse. you use the pointer notation for an array, and you dont make it clear that size is the length of the array. the only thing wrong with the current prototype is that MSVC does not support VLA declarations, but these will be made mandatory in C23

many people have this problem with not enough time to check... so you think first when you write new Kata

You can solve this with pen and paper faster than C. Think first, then code second.

A fast language is not enough to compensate a deficient algorithm. The kata is perfectly fine.

Hi, I wrote this Kata in C, but not enough time to check... fail. What is faster than C ? nothing :D I think this Kata is faulty...

Hi, in C language. The prototype of function is writen in not good practice. The variable n do not have to be part of array index. The value must be constant. This is the better writen prototype:

void powers_of_two(unsigned* arr, size_t size);

Fixed by changing class and method names to FindOccurrence.findNthOccurrence. Thank you!

The basic test does not work.....

Error:

./src/main/java/YourSolution.java:2: error: ',', ')', or '[' expected
public static int findOccurrence(String subStr, String str, int occurrence = 1) {
^
1 error

you need to convert to wanted doubles earlier (separate line), then do all the math on doubles.
then simple int(r) should work

I dont know, I try anything... :D

Are you sure? You are close, but read the instructions carefully. You are missing something important in the description.
