C++扑克牌的洗牌发牌游戏设计

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”

 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：
