comment Order array of points in counter clockwise
Sorting requires comparison (<, ==, >), its not obvious how to compare two dimensional data, that's why I suggest you to get angles between point centre and x or y axis.

I guess points are two dimensional data. So you could calculate angle between center and point. And since angle is one dimensional data now you can sort it using qsort.
