1、贪吃蛇游戏C语言源代码学习阅读学习了源代码，并做了简单的注释和修改，里面只用了链表数据结构，非常适合C语言入门者学习阅读。程序可在VS2013下编译运行。 1 #include 2 #include 3 #include 4 #include 5 6 #define U 1 7 #define D 2 8 #define L 3 9 #define R 4 /蛇的状态，U：上 ；D：下；L:左 R：右 10 11 typedef struct SNAKE /蛇身的一个节点 12 13 int x; 14 int y; 15 struct SNAKE *next; 16 snake; 17 18
