但问题是有不少人都不能意识到自己其实不懂某些问题。

我认为这样两种状态是没有问题的：
1.懂了，并且知道自己懂了
2.没懂，并且知道自己没懂
而LZ写的这种书，往往让人处于这样的状态：
3.没懂，但是认为自己懂了

    我以前就说了，比方要有用，要切中主题，现在你看到无用的比方罗~

because that's where it is in ISO C and C++

because that's not where memset() is supposed to be (however logical it
may seem to put it there)

他显然不可能支持用memory.h。
只有对你，这个显然才不那么显然。
居然需要为这种事情去打扰BS老头子。



另外：

BS的回答与我们的有何不同？因为他用英文？
为什么BS的话你就接受了？

那对那个等号，你是不是也该再去请教一个你信得过的权威？


早说了，你这人是假谦虚。表明上恭敬，骨子里根本就唯我独尊。
