C99的哪一部分说malloc（3）的返回值不应该被投放？
没有。标准只定义了语言，它不建议
良好的编程风格。

同一部分说你不应该把你的猫微波炉。
常规订阅者不推荐使用Castoc malloc在这个新闻组中
因为：
（a）它没有任何好处;
（b）它没有停止发生了什么不好的事情;
（c）它可以（在C90的某些情况下）实际上/导致/坏事
发生。
即使你没有被（a）和（b）一起说服（你可能也应该是b $ b），（c）应该是一个表明者。
malloc函数 - Just Don''t Cast。

这对我来说可能很愚蠢，但你的意思是不要施展为：
int * i =（int *）malloc（sizeof（int））;
？
那时还有哪些其他解决方案？只分配没有投票？

of malloc(3) should not be casted?
Thanks.

None. The standard only defines the language, it does not advise on
good programming style.

The same section that says you should not microwave your cat.
Casting malloc is deprecated by the regular subscribers in this newsgroup
because:
(a) it does nothing good;
(b) it doesn''t stop anything bad happening;
(c) it can (in certain circumstances in C90) actually /cause/ something bad
to happen.
Even if you''re not persuaded by (a) and (b) together (which you probably
should be), (c) should be a showstopper.
The malloc function - Just Don''t Cast.

int *i = (int *) malloc(sizeof(int));
?
What other solutions are there then? just assign w/o casting?
