C++扑克牌的洗牌发牌游戏设计分享！

笔者在大学二年级期间，做过的一次C++程序设计：扑克牌的洗牌发牌游戏。具体内容是：除去大王和小王，将52张扑克牌洗牌，并发出5张牌。然后判断这5张牌中有几张相同大小的牌，是否是一条链，有几个同花等。

笔者在学习他人设计的基础上，完成了自己的程序设计。这里将源程序分享给大家。 

[1] 文件“card.h”

  #ifndef CARD_H  #define CARD_H  #include<string>  using namespace std;    class Card  {  public:   static const int totalFaces=13;   static const int totalSuits=4;     Card(int,int);   int getFace();   int getSuit();   string toString();    private:   int face,suit;   static const string faceNames[totalFaces];   static const string suitNames[totalSuits];    };  #endif // CARD_H 

[2] 文件“card.cpp”

  #include"card.h"    Card::Card(int faceNumber,int suitNumber)  {   face=faceNumber;   suit=suitNumber;  }    string Card::toString()  {   return faceNames[face]+" of "+suitNames[suit];  }    int Card::getFace() {return face;}  int Card::getSuit() {return suit;}    const string Card::faceNames[totalFaces]=  {"A","2","3","4","5","6","7","8","9","10","J","Q","K"};    const string Card::suitNames[totalSuits]=  {"heart","diamond","club","spade"};

[3] 文件“deckofcards.h”

  #ifndef DECKOFCARDS_H  #define DECKOFCARDS_H  #include<vector>  #include"card.h"  using namespace std;    class DeckOfCards  {  public:   static const int fiveCards=5;   static const int allCards=52;   DeckOfCards();   void shuffle();   Card dealCard(int);     void sortCards();   int duiziCards(int* sortFaces);   //bool moreCards();    private:   vector<Card> deck;   int currentCard;    };  #endif // DECKOFCARDS_H

[4] 文件“deckofcards.cpp”

  #include"deckofcards.h"  #include<cstdlib>  #include<ctime>    DeckOfCards::DeckOfCards()  {   //currentCard=0;     for(int i=0;i<allCards;i++)   {   Card card(i%Card::totalFaces,i/Card::totalFaces);   deck.push_back(card);   }  }    void DeckOfCards::shuffle()  {   srand(time(0));     int swapRandom[allCards];     for(int i=0;i<allCards;i++)   swapRandom[i]=int(rand())%allCards;     for(int i=0;i<allCards;i++)   {   Card swapCard(0,0);   swapCard=deck[i];   deck[i]=deck[swapRandom[i]];   deck[swapRandom[i]]=swapCard;   }    }    Card DeckOfCards::dealCard(int how_many)  {   for(int i=0;i<how_many;i++)   {   cout <<deck[i].toString() <<endl;   if((i+1)%13==0) cout <<endl;   }  }    void DeckOfCards::sortCards()  {   int sortFaces[fiveCards];   int sortSuits[fiveCards];   for(int i=0;i<fiveCards;i++)   {   sortFaces[i]=deck[i].getFace();   sortSuits[i]=deck[i].getSuit();   }     for(int i=fiveCards-1;i>=0;i--)   for(int j=0;j<=i-1;j++)   if(sortFaces[j]>sortFaces[j+1])   {   int t;   t=sortFaces[j];   sortFaces[j]=sortFaces[j+1];   sortFaces[j+1]=t;   }     if((sortFaces[0]==sortFaces[1]&&sortFaces[0]==sortFaces[2]&&sortFaces[0]==sortFaces[3])||   (sortFaces[1]==sortFaces[2]&&sortFaces[1]==sortFaces[3]&&sortFaces[1]==sortFaces[4]))   cout <<"There are 4 same cards." <<endl;     else if((sortFaces[0]==sortFaces[1]&&sortFaces[0]==sortFaces[2])||   (sortFaces[1]==sortFaces[2]&&sortFaces[1]==sortFaces[3])||   (sortFaces[2]==sortFaces[3]&&sortFaces[2]==sortFaces[4]))   cout <<"There are 3 same cards." <<endl;     else if(int i=duiziCards(sortFaces))   cout <<"There are " <<i <<" pairs." <<endl;     else   cout <<"There is no same cards." <<endl;     if(sortFaces[0]+1==sortFaces[1]&&sortFaces[1]+1==sortFaces[2]&&   sortFaces[2]+1==sortFaces[3]&&sortFaces[3]+1==sortFaces[4])   cout <<"The five cards is a straight." <<endl;   else   cout <<"The five cards is not a straight." <<endl;     if(sortSuits[0]==sortSuits[1]&&sortSuits[0]==sortSuits[2]&&   sortSuits[0]==sortSuits[3]&&sortSuits[0]==sortSuits[4])   cout <<"The five cards have same flower." <<endl;   else   cout <<"The five cards have different flower." <<endl;    }    int DeckOfCards::duiziCards(int* sortFaces)  {   int duiziNum=0;     for(int i=0;i<fiveCards-1;i++)   if(sortFaces[i]==sortFaces[i+1]) duiziNum++;     return duiziNum;  } 

[5] main函数文件“main_FiveCards.cpp”

  #include<iostream>  #include"card.cpp"  #include"deckofcards.cpp"  using namespace std;    int main()  {   DeckOfCards aDeck;     cout <<"Deal all cards before shuffle." <<endl;   aDeck.dealCard(aDeck.allCards);     aDeck.shuffle();     cout <<"Deal five cards after shuffle." <<endl;   aDeck.dealCard(aDeck.fiveCards);     cout <<"nThe result after sorting." <<endl;   aDeck.sortCards();     return 0;  }

将5个文件放在同一目录下，对文件“main_FiveCards.cpp”编译运行即可。以下是在CodeBlocks中的运行结果：
