编译方法：
AIX下：cc -qcpluscmt -o snake snake.c
sco unix下：cc -o snake snake.c
[ 本帖最后由 forest077 于 2008-6-25 13:23 编辑 ] 代码写得很漂亮，支持，友情帮顶！:) gcc加了-Wall选项之后出现了N多警告，主要是一些头文件没加进去；
另外，不知道搂主是在什么环境下跑这个程序的，我的机器跑了之后没看到什么。
回复 #3 LinuxKen 的帖子
我在AIX下开发的。 sco下虽然没试过，但是以我的经验，跑起来应该没问题。 跑了就看到个界面， 看不到蛇和豆子， 一会就 GAME OVER了 我还记得刚来CU时看到LZ在shell版发的shell学习体会~~:mrgreen: :mrgreen:
回复 #5 204tian 的帖子
你在什么环境下的？linux下我不敢保证可以运行。回复 #6 converse 的帖子
哈哈，多谢，你还记得呀 可惜我这边找不到linux环境，要不然可以试试 Segmentation fault (core dumped)在AIX下。。。
