这个程序是在网上找到的,但一直看不懂.请哪位高手看一下.帮忙看一下.

{0,8,4,1,(*fun0)}, //0//第一层，显示[彭勋]，马鹏辉，返回
{1,3,2,1,(*fun1)},//1-0按回车，进第二层，显示[湖工]，湘潭，返回

{2,1,3,2,(*fun2)},//4-1向下，显示湖工，[湘潭]，返回

{3,2,1,0,(*fun3)},//7-4向下，显示湖工，湘潭，[返回]

{4,0,8,5,(*fun4)},//12-0 >down>显示彭勋，[马鹏辉]，返回
{5,7,6,5,(*fun5)},//13-12 >enter>[河南]，湖工，返回

{6,5,7,6,(*fun6)},//16-13 >down>河南，[湖工]，返回
{7,6,5,4,(*fun7)},//19-16 >down>河南，湖工，[返回]

{8,4,0,8,(*fun8)},//22-19 >down>彭勋，马鹏辉，[返回]

这些是什么意思啊,程序是怎么走的啊.主程序里也看不懂.希望高手们能看看,帮忙说一下,谢谢了

今天终于看懂了.只要看前面的序号就行了.

kongjie07 发表于 2010-11-25 22:54:21

顶！

liaogang1314 发表于 2010-11-26 08:29:39

这个代码不行的每移动一下都是整屏刷新！

tangshanqiang 发表于 2010-11-26 08:49:43

楼上发一个吧，我也想做一个呢

haydon123 发表于 2011-4-21 18:55:54

代码不行也顶

cumtgao 发表于 2011-5-12 14:00:42

看看

ARMXIN 发表于 2011-5-12 14:09:07

不会先标记

cumtgao 发表于 2011-5-13 10:10:42

晕代码好像有问题。。。。
