一个 C语言源代码算法

答案：牌类这样定义：
class CCard
{
public:
 int m_nColor;  //花色;
 int m_nValue;  //面值;
 int m_nSize;   //实际计算的大小
public:
 CCard();
};
CCard::CCard()
{
 m_nColor = 0;     //0表示没有任意花色;
 m_nValue = 0;   //0表示还没有牌;2-10-K-A对应2-10-13-14，小、大王对应16,17
 m_nSize = 0;      //打几子那张牌大小设为15，用于比较牌值
}
//全局
static HBITMAP g_hBmpCard[55];//前0-51主牌52牌背53小王54大王
CCard g_cAllCards[108];
CPlayer pPlayers[4];//记录玩家信息的类
int g_nDaJiZi = 2;    //本次打几子,针对m_nValue： 2-10-K-A对应2-10-13-14
//牌的初始化及洗牌

{
 //将牌放入;

   //牌背和小、大王   
   g_hBmpCard[52] = (HBITMAP)::LoadImage(NULL,_T(".\\sk\\111.BMP"),IMAGE_BITMAP,71,96,LR_LOADFROMFILE);

   g_hBmpCard[54] = (HBITMAP)::LoadImage(NULL,_T(".\\sk\\4-17.BMP"),IMAGE_BITMAP,71,96,LR_LOADFROMFILE);
}
根据牌算得牌是数组g_hBmpCard[]中的第几个
    int nCard = (pPlayers[0].m_Card[i].m_nColor-1)*13+pPlayers[0].m_Card[i].m_nValue-2;
   //(4-1)*13+16-3=52是小王
