C++实现派生类的基本函数

[已关闭问题] 关闭于 2017-09-26 21:30

C++新手，在尝试搞清楚派生类基本函数的问题上遇到下面问题：

 1 #include<iostream.h>
 2 
 3 class Base
 4 {
 5     public:
 6         virtual ~Base()
 7         {
 8             cout << "Base::~Base()" << endl;
 9         }
10 };
11 
12 class Derived : public Base
13 {
14     public:
15         virtual ~Derived()
16         {
17             delete p_test;
18             cout << "Derived::~Derived()" << endl;
19         }
20 
21     private:
22         char *p_test;
23 };
24 
25 void main(void)
26 {
27     Base *pB = new Derived;
28     delete pB;
29 }
