card.h 结构体card表示一张牌，
// note, the typedef name is "cardT", the struct name is "struct card"typedef struct card {int rank;char suit;struct card *next; // Be sure you understand what data type "next" is} cardT;cardT *makeCard(int rank, char suit); // will need to allocate space!cardT *shuffle(cardT *pile); // provided for youint countPile(cardT *pile); // provided for you// Include the other required prototypes below
card.c：新建牌组，洗牌功能。

makefile文件：用于编译游戏，test是用是链接到老师给定的.o文件。
