在linuxforum上有过讨论

因为在unix下
unix宏被定义成1
但是在其它平台下没有定义
所以会有问题

第一次见到这样怪的代码，还是第一次见到在代码中出现中括号，不知道它的用法是怎么样的？哪位大侠给解释一下，谢谢：）

biansj

第一道题目解答：

主要考虑两个知识点：
1.unix是一个宏,值为1
2.a[1]==*(a+1)==*(1+a)==1[a]

其他的自己用printf试一试就知道了.

第二道真是晦涩我也没有分析完,期待ing...

谁规定老头就不能说粗话啦,不过对于像你这样的祖国花朵是有一些玷污.    

下次注意!

不理解最后这个1[a]...
是个什么意思？
