本文介绍了一种使用C++实现的宠物机器人对话系统，通过继承和多态，创建了能够发出特定声音的猫和狗类。主要展示了如何设计类结构，实现虚拟宠物的基本交互。

源代码：

MachinePets.h:

#ifndef MACHINEPETS_H
#define MACHINEPETS_H
#include <string> 
using namespace std;
class MachinePets{
    public:
        MachinePets(const string s);
        string getNickname() const;
        virtual string talk()=0;
    private:
        string nickname;
};
#endif

MachinePets.cpp：

#include "MachinePets.h"
#include <string>
using namespace std;
MachinePets::MachinePets(const string s):nickname(s){
}
string MachinePets::getNickname()const{
    return nickname;
}

PetCats.h:

#ifndef PETCATS_H
#define PETCATS_H
#include <string>
using namespace std;
#include "MachinePets.h"
class PetCats:public MachinePets{
    public:
        PetCats(const string s);
        string talk();
};
#endif

PetCats.cpp:

#include <string>
#include "PetCats.h"
using namespace std;
PetCats::PetCats(const string s):MachinePets(s){
}
string PetCats::talk(){
    return "miao wu~";
}

PetDogs.h:

#ifndef PETDOGS_H
#define PETDOGS_H
#include <string>
#include "MachinePets.h"
using namespace std;
class PetDogs:public MachinePets{
    public:
        PetDogs(const string s);
        string talk();
};
#endif

PetDogs.cpp:

#include <string>
#include "PetDogs.h"
using namespace std;
PetCats::PetDogs(const string s):MachinePets(s){
}
string PetDogs::talk(){
    return "wang wang~";
}

main.cpp:

#include <iostream>
#include <string>
using namespace std;
#include "MachinePets.h"
#include "PetCats.h"
#include "PetDogs.h"
void play(MachinePets *x){
    cout<<x->getNickname()<<"says"<<x->talk()<<endl;
}
int main() {
    PetCats cat("miku");
    PetDogs dog("dahuang");
    play(&cat);
    play(&dog);
    return 0;
}
