This C Program Finds the Closest Pair of Points in an Array. int x, y / sort array of points according to X coordinate For example: sizeof(scores)/sizeof(int), where scores is an array of ints. This does not work with pointers.This means that if we have a pointer to an array in C, there is no way to find out how many elements the pointer points to it points to however many you imagine it to point to, and you
