Thread: need help with destructor

I have a class named PolyLine with the following data members:

double *xArray;
double *yArray;
int length;

I have a destructor:

~PolyLine()
{
cout << "I'm destroying you";
delete [] xArray;
delete [] yArray;
}

when I delete a PolyLine:

delete p1;//where p1 is a pointer to a PolyLine

The text "I'm destroying you" is printed but the object can still be printed. Could someone tell me what I am doing wrong ? Thanks
