C++ 析构函数

C++编程思想第六版 P429

2018/8/20 继承关系中析构函数的调用顺序

#include<iostream>
using std::cin;
using std::cout;
using std::endl;
class Character
{
public:
    virtual ~Character()
    {
        cout << "Character released" << endl;
    }
};

class NPC : public Character
{
public:
    virtual ~NPC()
    {
        cout << "NPC released" << endl;
    }
};

int main(void)
{
    NPC* npc = new NPC();
    delete npc;
    cin.get();
    return 0;
}

运行结果

 

可以看出子类先释放，父对象后释放
