1、8乘8点阵贪吃蛇源代码/writer: neolone/bug:当蛇身全部在第二列上时，第四列会同时显示/问题1：蛇的最大长度是33，因为51存储空间不足了，其实可以用一位uchar存储两个数，用它/的十位个位就行/问题2：随着蛇的增长速度会减慢，因为每显示一节就会delay（2），这样就会增加时间，可以把151行的延时做成随length增加减少的量/我懒得改了，如果你改好的话希望发一份到我邮箱lllllbbbbbsz，在此先谢过了#include #include #define uchar unsigned char#define TRUE 1#define FALSE 0#define
