向量分割错误

C++ - Vector Segmentation Error

本文关键字:错误 分割 向量      更新时间:2023-10-16

我目前正在为我的大学课程做一个名为Blackjack的CMSC项目。我一直试图在另一个类中添加一个名为卡片的向量对象。Hand类作为对象存储在Player类的另一个向量中。

我的问题是,我试图调用OutputPlayerHand方法在一个类称为Blackjack,但我得到一个分割错误。

这是我的Blackjack.cpp类的代码。

#include "Blackjack.h"
#include <iostream>
Blackjack::Blackjack()
{
  // Initialize the dealer
  Player dealer((char *) "Dealer", 100);
  m_dealer = dealer;
  // Initialize a player 'Jane' with 100 funds
  Player player((char *) "Jane", 100);
  m_players.push_back(player);
}
Blackjack::Blackjack(char *names[], int numPlayers)
{
  // Initialize the dealer
  Player dealer((char *) "Dealer", 100);
  m_dealer = dealer;
  // Loop through all passed player names
  for(int i = 0; i < numPlayers; i++)
    {
      // Initialize a player 'names[i]' with 100 funds
      Player player(names[i], 100);
      m_players.push_back(player);
    }
}
int Blackjack::GetNumPlayers()
{
  // Return the size of the players vector
  return m_players.size();
}
char *Blackjack::GetPlayerName(int player)
{
  // Return the requested player's name
  return m_players[player].GetName();
}
int Blackjack::GetPlayerFunds(int player)
{
  // Return the requested player's funds
  return m_players[player].GetFunds();
}
void Blackjack::SetPlayerFunds(int player, int amt)
{
  // Set the requested player's funds
  m_players[player].SetFunds(amt);
}
bool Blackjack::SetPlayerBet(int player, int amt)
{ 
  // If the player has insufficient funds
  if(m_players[player].GetFunds() < amt)
    {
      // Return false
      return false;
    }
  // Subtract the amount from the player funds
  m_players[player].SetFunds(m_players[player].GetFunds() - amt);
  // Add the amount to the player bet
  m_players[player].SetBet(amt);
  // Return true
  return true;
}
void Blackjack::NewDeal()
{
  // Create a new unsorted 52 card deck
  Deck deck;
  // Initialize m_deck to the new deck
  m_deck = deck;
  // Shuffle m_deck
  m_deck.Shuffle();
  // 2 cards for dealer, 2 cards for each player
  int cardsToDeal = 2 + (2 * m_players.size());
  // While we still have cards to deal
  while(cardsToDeal > 0)
    {
      // Deal to each player
      for(unsigned int i = 0; i < m_players.size(); i++)
    {
      std::cout << "Deal Player Card" << std::endl;
      // Deal one card to the player
      m_players[i].GetHand().AddCard(m_deck.DealCard());
      // Decrement the number of cards to deal
      cardsToDeal--;
    }
      std::cout << "Deal Dealer Card" << std::endl;
      // Deal the dealer one card
      m_dealer.GetHand().AddCard(m_deck.DealCard());
      // Decrement the number of cards to deal
      cardsToDeal--;
    }
}
void Blackjack::OutputPlayerHand(int player)
{
  std::cout << "Player Output Card." << std::endl;
  m_players[player].GetHand().GetCard(0).OutputCard();
}
void Blackjack::OutputDealerHand()
{
  // TODO: Code Method
}
bool Blackjack::HitPlayer(int player)
{
  // TODO: Code Method
  return false;
}
void Blackjack::DealerPlay()
{
  // TODO: Code Method
}
int Blackjack::SettlePlayerBet(int player)
{
  // TODO: Code Method
  return -1;
}

这是我的Player.cpp类的代码。

#include "Player.h"
Player::Player()
{
  m_name = (char *) "Jane";
  m_funds = 100;
  m_bet = 0;
}
Player::Player(char *name, int funds)
{
  m_name = name;
  m_funds = funds;
  m_bet = 0;
}
char *Player::GetName()
{
  return m_name;
}
void Player::SetName(char *name)
{
  m_name = name;
}
int Player::GetFunds()
{
  return m_funds;
}
void Player::SetFunds(int funds)
{
  m_funds = funds;
}
int Player::GetBet()
{
  return m_bet;
}
void Player::SetBet(int bet)
{
  m_bet = bet;
}
Hand Player::GetHand()
{
  return m_hand;
}

下面是Hand.cpp类的代码。

#include "Hand.h"
void Hand::AddCard(Card card)
{
  m_cards.push_back(card);
}
Card Hand::GetCard(int card)
{
  return m_cards[card];
}
int Hand::Size()
{
  return m_cards.size();
}
void Hand::Clear()
{
  m_cards.clear();
}

下面是我的主类project .cpp的代码。

/*
 * CHANGES TO Blackjack.h SPEC:
 *   added new member funcs:
 *     char *GetPlayerName(int)
 *     int GetNumPlayers()
 *     void OutputDealerHand()
 *
 *   HitPlayer() should print out the card that was dealt.

谁能告诉我我做错了什么?我不允许以任何方式编辑Proj2.cpp类。如果您需要更多的信息,请不要犹豫,问。如果你想看完整的项目,这里有一个到Github仓库的链接。如果你需要看我的项目规则和说明,这里有一个链接到我的课程项目描述网站。

在这件事上任何帮助都是非常感激的,提前感谢您的时间。

Hand为空。

这一行:m_players[i].GetHand().AddCard(m_deck.DealCard())只将一张卡添加到临时副本中让GetHand()返回一个参考,你的玩家将真正得到卡牌。

同样,你不应该包含像Prog2这样的可执行文件。
