老师布置一个作业，让自己编一个程序，养宠物问题，希望高手帮我一下。

看看是什么情况？着急用啊，如果您会的话帮帮我

就是像这样的
#include<iostream>
#include<string>
using namespace std;
class pig
{public:
virtual void pzsl()
{}
private:
string fur_color;
};
class wuglwhite:public pig
{public:
void pzsl ()
{cout<<"yumi+zhengdasiliao6jin"<<endl;
}};
class wuglblack:public pig
{
public:
    void pzsl()
    {cout<<"dami1jin+zhenghongsiliao3jin"<<endl;
}};
    class shouroupig:public pig
    {
    public:voidpzsl()
           {cout<<"tudou+yumi"<<endl;
           }
    };
    void machine (pig*pg)
    {pg->pzsl();}
    void main()
    {
        wuglwhite xiaobai;
        wuglblack heihei;
        shouroupig shourou;
        machine (&xiaobai);
        machine (&heihei);
        machine (&shourou);
    }
