#include <iostream>
#include <string>
using namespace std;
class MachinePets{
public:
    MachinePets(const string s):nickname(s){
    };
    string getNickname(){
     return nickname;
     };
    virtual string talk()=0;
private:
    string nickname;    
};
class PetCats:public MachinePets{
    public:
        PetCats(const string s):MachinePets(s){
        };
        string talk() {return "miao wu~";}
};
class PetDogs:public MachinePets{
    public:
        PetDogs(const string s):MachinePets(s){
        };
        string talk() {return "wang wang~";};
};
void play(MachinePets *p){
    cout<<p->getNickname()<<"says"<<p->talk()<<endl; 
}
int main()
{  PetCats cat("miku");
   PetDogs dog("da huang");
   play(&cat);
   play(&dog); 
   return 0;
}

总结：一开始在vs里面每个程序分开做的，但是总是有小的问题报错，然后换了dev做的。其实程序不是特别难，理解起来也特别容易，但是我做起来总有这样那样的小错误，掌握的不是特别好。
