Passing an array to a Class (Library) instance?

Hopefully a simple question of syntax...

I have a class (Library) that I need two instances in my program but initialized with different values - arrays of non-consecutive numbers. I want to pass those arrays in when I init the instances. I am getting errors about 'incompatible types' int* and int.

What I am trying to do seems pretty basic. Is it just the wrong syntax? I can see some hack-around solutions but would like to understand how to do this right.

thanks! --Roy

In my sketch:

  int LC[] = {0,1,2,3,4,5,6,7,16,17,18,19};
  leftCircle.init('L',LC, 1, 25);

The .h file

#define CircleSmall_h
  
 #include "WProgram.h"
 
class CircleSmall
{
  public:
  int direction;
  int delayPeriod;
  int[] lightArray;
  CircleSmall();
  void init(int, int[], int, int);
};

#endif

The implementation (.cpp):

#include "CircleSmall.h"
 
CircleSmall::CircleSmall(){
//
}
 
void CircleSmall::init(int i, int L[] , int d, int p){
    id = i;    
    lightArray = L; 
    direction = d;
    delayPeriod = p;
}
2 
    lightArray = L;

You can't assign one array to another like this. You need to copy all the elements of one array to the other, or use memcpy to copy the whole block.
