Question

我想阅读包含玩家及其预算的文本文件。播放器应存储在二进制最大堆中。堆由玩家的当前预算确定优先级，并且必须是基于数组的堆。我添加了部分代码，但我有以下混淆：

我在构造函数中的读数是否正确？
复制构造函数是对吗？
我不知道如何继续。有人可以指出我接下来应该做什么吗？

这是Heap.h

#ifndef HEAP
#define HEAP

class Heap{
    public:
        Heap(string filename);// read the name and budget 
        Heap(const Heap &copy);
        void addPlayer(Player* newPlayer); // add player to the heap
        Player getPlayer();
        bool empty();
        unsigned int size(); // return number of nodes in heap
        void RemovePriorityPlayer(int heighest);
        // you still need heasp
        std::vector<Player> getArray();
};

#endif

这是Heap.cpp

Heap::Heap(string filename) 
{
   std::ifstream str;
   str.open(filename, ifstream::in);
   str.close();
}

Heap(const Heap &copy)
{
   std::if stream copy.str;
}

void addPlayer(Player* newPlayer) // add player to the heap
{
    string name;
    int budget;
    cin>>name>>budget;
    Player* pNewPlayer = new Player(name,budget);

    //if list is empty, make head of list this new player

    if(m-pHead == 0){
        m-pHead = pNewPlayer;
        m-pTail = m-pHead->GetNext();
    }
    else // otherwise find the end of the list and add the player there
    {
        m-pTail = pNewPlayer;
        m-pTail = m-pTail->GetNext();
    }
}

Player.h

#ifndef PLAYERS
#define PLAYERS

class Player{
    public:
        int Card_hand;
        Player(string name, int budget);
        string getName();
        int getBudget();
        bool bet(int amount);
        void collectWinnings(int amount); 
};

#endif

max-heap如何实现以下锦标赛？
