数据结构：扑克发牌算法

扑克发牌算法
扑克中的元素由两种内容组成：花色和面值。 花色：黑桃、红桃、方块、草花； 面值：A、2、3、4、5、6、7、8、9、10、J、Q、K。 一副不含Joker的牌共52张（13*4）张。 现在要实现给四个人（Player）发牌。

#include<stdio.h>
#include<stdlib.h>
#include<time.h>

#define  POKERS_COUNT  52
#define POKER_TYPE_COUNT  13

const char *pokerType[] = {"黑桃", "红桃", "方块", "草花"};   //const 常量，只读   指针数组
const char *pokerValue[] = {" A", " 2", " 3", " 4", " 5", " 6", " 7", " 8", " 9", "10", " J", " Q", " K"};

//[]和pokerType优先结合  const char*   pokerType[] = {"黑桃", "红桃", "方块", "草花"};   不加个数是为了方便以后进行修改
//数组，有四个元素，每个元素是char*，是四个字节，和里面的内容没有任何关系
//关于数组指针和指针数组详细参见 https://blog.csdn.net/weixin_42072280/article/details/83210655
