count++;
}~Point()
{
count--;
}
int getX(){return x;}
int getY(){return y;}
static void showCount()
{
cout<<"Object count="<<count<<endl;
}
private:
int x,y;
static int count;
};
int Point::count=0;
int main()
{

cout<<"Point A:"<<a.getX()<<","<<a.getY();
Point::showCount();
Point b(a);
cout<<"Point B:"<<b.getX()<<","<<b.getY();
