class Coach{
    string name;
    int winRate;
public:
    Coach(string n, int wr){
        name=n; winRate=wr;
    }
    void show();
};
class Club{
    string name;
    Coach c;
    int year;
public:
    Club(string n1, int y, string n2, int wr);
    void show();
};

Club的初始化和show函数要利用Club类中的东西

Club::Club(string n1,int y,string n2,int wr):c(n2,wr){
    name = n1;
    year = y;
}
void Club::show(){
    cout << name << " " << year << "\n";
    c.show();
}

同样，在下面Circle调用内部Point类型的变量，要有Point中的get函数配合才能取出相应的x,y

                if(x < r)return true;
                return false;
            }
