Inside the for loop of my SetPoints() method which is in the Polygon class Im trying to assign the values of the parameter arrays into a class array, but its not working, the class array just continues to hold garbage values. I have a few debugging output statements that show that. Can anyone tell me whats wrong?
Code:
#include <iostream>
#include <string>

using namespace std;

class Point
{
private:
   int x;
   int y;
public:
   Point();
   Point(int takeX, int takeY);
   void Set(int pntX, int pntY);
   int GetX();
   int GetY();
   void DisplayPoint();

};
class Polygon
{
private:
   int num_points;
   static const int MAX_POINTS = 100;
   string points[MAX_POINTS];

public:
   Polygon();
   Polygon(int polySize, int xArray[], int yArray[]);
   void SetPoints(int polySize, int xArray[], int yArray[]);
   string ShowPolygon();
   void AddPoint(int x, int y);
   void AddPoint(Point p);
   void ClearPoly();
