C++分享笔记：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。

[5] main函数文件“main_FiveCards.cpp”

 #include<iostream>

 using namespace std;

     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 ;
 }

　　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：
