继承编译问题

Question

我正在做一个涉及卡片游戏课程的项目，可以玩Go Fish或Poker。但是，当我尝试编译文件时，我在{“错误之前收到了”预期的类名。我将仅包含Go Fish界面以避免读者麻烦。下面是我试图编译的代码。

//card_games.h
#ifndef CARD_GAMES
#define CARD_GAMES
#include "go_fish.h"
#include "poker.h"
#include "player.h"
#include "deck.h"

class card_games{

      public:      
                   card_games();
                   void checkplayer(char thePlayer);
                   void convert(char);
                   void distribute();
                   void givecard();
                   void printhand();
                   ~card_games();

      protected:
                  int num_player; //number of players
          int player_num; //player's turn    

      private:
                  go_fish fishing; //gofish object
                  poker gamble;  //poker object
                  deck pool; //pool object
                  player* p;     //array of players
};
#endif

//go_fish.h
#ifndef GO_FISH
#define GO_FISH
#include "player.h"
#include "deck.h"
#include "card_games.h"

class go_fish: public card_games{   *//error occurs here*
      public:
                 void startgame(int &player_num);
             void checkrank(char&);
         void hunt_card(int, int);
         void choose(char&);
         void checktarget();
         void gofish();
         void stalemate();
         void victory();
         void swapturns();

         player getplayer(int);
         ~go_fish(){};

      protected:

      private:    
               int decision;
       int target;
       char choice;  
};
#endif

//deck.h
#ifndef DECK
#define DECK
#include <iostream>
#include <vector>
#include <string>
#include <cstring>
#include <cstdlib>
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#include "card.h"

using namespace std;


class deck{
      public:
        deck();
    card getd(int); //accesor
    vector <card> getdeck();
    void setcard(int, int, int);
    void assign();
    void assignrank();
    void shuffle();
    void printdeck();
    void remove_top(int &deck_index);
    void remove_topcard(int);
    void deck_size();
    int getdsize();
    ~deck();


      protected:


      private:    
        vector <card> d;
};

#endif

//player.h
#ifndef PLAYER
#define PLAYER
#include <iostream>
#include <vector>
#include <string>
#include <cstring>
#include <cstdlib>
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#include "card.h"

using std::vector;

class player{

  public:
         card getHand(int); //accesors
         vector <card> gethand();
         void printhand();
         int gethandsize();
         bool checkdecision(int* decision);
         bool compare(int decision, player& thief);
         void steal(card);
         void discard(int decision);

     protected:



     private:      
         vector <card> h;
};
#endif

对任何缩进头痛道歉。

Answer 1

上述评论中的解释暗示go_fish不应继承card_games。如果有的话，也许card_games可以继承go_fish和poker，但可能不会。 card_games类很可能只是使用聚合（例如has-a relationship）而不是继承。不知道整个设计，我的想法可能与意图不一致。请检查设计并做出决定。可以把它想象成第一次尝试是迭代零，下一次尝试是迭代一次，然后是迭代二次等等。
