Create an array of struct and clear it?

Question

I have following struct

typedef struct {
    double x;
    double y;
} Point;

I want to create an array of it with defined size and clear it use this code:

Point *temppoints = new Point[pointCounts];
delete []temppoints;

However Xcode won't compile because of the new and delete.

Any advise?

@SeekAddo lol honestly no, because mainly I will do the code in Objective-C, very rarely to use C code — Rendy, Jul 24 '17 at 03:05
lol. i see, because this things are basically well explained in the books. — Seek Addo, Jul 24 '17 at 03:06
@maddy: No, but according to a comment OP intends to use it. Not sure how to allocate memory in ObjC, though; AFAIK it has a garbage collection, so `malloc` does not make much sense, does it? I VtC as unclear; OP might want to read a book about the basics before starting whatever he intends. — too honest for this site, Jul 24 '17 at 03:53
Try an earlier answer from the stack (as it were). Also, apple University has entire courses online re objective C and Xcode. [Here](https://stackoverflow.com/questions/8748114/new-and-delete-command-of-c-in-obj-c) — dcy665, Jul 24 '17 at 03:39

The new and delete keywords are C++ only. If you're using C, you need to use the malloc and free functions:

Point *temppoints = malloc(pointCounts * sizeof(Point));
...
free(temppoints);
