 6 public:
 7     int i = 10;
 8     void show()
 9     {
10         cout << "myclass" << i << endl;
11     }
12 };
13 
14 class mynewclass :public myclass
15 {
16 public:
17     int i = 100;
18     void show()
19     {
20         cout << "mynewclass" << i << endl;
21     }
22 };
23 
24 void main()
25 {
26     myclass *p1 = new myclass;
27     //父类指针可以存储子类地址
28     myclass *p2 = new mynewclass;
29     p1->show();
30     p2->show();
31     cin.get();
