/*HW13_2. 洗牌程序. 用一个结构数组保存52张牌, 每张牌包含花色和面值. 首先按照花色
和面值初始化结构数组(正如我们买到的新牌), 然后利用随机数进行洗牌. 输出洗牌结果.
要求如下:
1) 保存花色的指针数组,
char *suits[] = {"Spades", "Hearts", "Diammonds", "Clubs"};
保存面值的指针数组,
char *faces[] = {"Ace", "Deuce", "Three", "Four", "Five", "Six", "Seven",
"Eight", "Nine", "Ten", "Jack", "Queen", "King"};
2）定义初始化纸牌的函数initCards(), 按照花色和面值初始化纸牌结构数组.
3）定义输出纸牌的函数outputCards(), 输出52张纸牌的花色和面值.
4）定义洗牌函数shuffle(), 洗牌算法: 循环考察结构数组中的每个元素,
用随机数函数生成一个52以内的随机数, 将当前考察元素与下标为随机数的元素交换.
