大语言模型的token详解

运用虚函数实现多态

#include <iostream>

using namespace std;

class Animal
{
public:
    virtual void perform()=0;
    virtual ~Animal()
    {
        cout  << "释放父类空间" <<endl;

    }
};

class Monkey:public Animal
{
public:
    void perform()
    {
        cout << "猴子正在骑自行车" << endl;
    }
    ~Monkey()
    {
        cout << "释放子类空间" << endl;
    }
};
class Elepant:public Animal
{
public:
    void perform()
    {
        cout << "大象正在滚皮球" << endl;
    }
};
class Lion:public Animal
{
public:
    void perform()
    {
        cout << "狮子正在跳火圈" << endl;
    }
};
int main()
{
    Animal *p;
    Monkey s1;
    p=&s1;
    p->perform();
    Lion s2;
    p=&s2;
    p->perform();
    Elepant s3;
    p=&s3;
    p->perform();

    cout << "Hello World!" << endl;
    return 0;
}
