   struct Circle
   { int x, y, r;
   };
   
   struct LinkedList
   { Circle C;
     LinkedList* pNext;
   };
   
   void ShowCircle(Circle c)
   {
       cout << "center: (" << x << "," << y << ")\t radius: "
           << r << "\n";
   }
   
   int main(void)
   {
       Circle C1 = {1, 2, 3};
       Circle C2 = {4, 5, 6};
       ShowCircle(C1);
       LinkedList* p = new LinkedList;
       p->C = C1;
       p->pNext = new LinkedList;
       p->pNext->C = C2;
       ShowCircle(p->pNext->C);
   }
