106.多态与虚函数

#include <iostream>
using namespace std;

class Aobject
{
public:
    //虚函数提供一个接口,自动选择子类的接口
    //存储某个对象的地址,调用对应的方法
    virtual void show()
    {
        cout << "Aobject" << endl;
    }
    
};

class Bobject :public Aobject
{
public:
    void show()
    {
        cout << "Bobject" << endl;
    }
};

void main()
{
    Aobject *p = new Bobject;
    p->show();
    cin.get();
}
