- [chinatree] 不要一味的要求什么. 01/09 01:58
- [sa2y] 为什么许多课本就不能编写成小说一样的通俗易懂吗？是不是编者不肯这样写，怕别人超过自己，还是编者也是抄 01/08 19:25
- [fanqingtulv] 不错，， 11/27 18:36
- [lanerxl] 我好悔啊，现在才意识到汇编的重要性。。。加油啊，我们大家都要坚持下去，我现在在看第三章 11/16 10:01
- [avf11] 加油!我们共同努力! 10/26 09:58
- [guangzi477273] 努力 10/08 12:27
- [lyang] 我想在也是刚学汇编，在网上找到了这网站。感觉很好 共同努力啊 09/21 14:36
- [mywiil] 感同身受啊！ 09/15 16:29
- [pbt124] 我和你一样也是非专业，也是爱好者。也是很迷茫，不知道学什么曾经。支持你。。坚持 08/31 09:52
- [游客] 恩 一年前 我也有博主之感觉，回想当时心情之亢奋，尤如昨日 哈哈，加油学！！！ 08/17 21:04
- [dsmilely] 我的情况和你非常相似，可以交个朋友吗，大家一起学习。我QQ：512230103 04/09 22:56
