C

bit fields -- they aren't well specified by the language and how they work is compiler dependent and architecture dependent. It's often hard to find where a particular symbol is defined in a large mass of code, esp. if that symbol is produced by a macro. Which reminds me... The preprocessor is a rather ugly hack, amenable to all sorts of abuse. lack of standard sized integers (remedied by uint*_t lately, but there is lots and lots of old code floating around out there with custom typedefs or #defines for DWORD, WORD, BYTE, etc.) Lack of something akin to Perl's cpan.org (would love to be wrong about that one.)

编辑: 在考虑C的CPAN时，我想……我该怎么称呼这样的东西，然后想到了“ccan”，然后谷歌了一下，我看到了这个: http://ccan.ozlabs.org/

不过，它似乎还处于起步阶段。

R (R- project for statistics)

糟糕透顶的字符串支撑 对于一些简单的描述任务，比如交叉表格，是非常困难的 大型数据集操作是在内存中完成的。

很多人认为Java很慢，但我同意一定程度的使用。

Java是戏剧性的。他们为你想做的一件事提供了很多课程。但是你知道灵活性属性XD。

Java一开始很难，但总是很有趣。

当你写一个简单的代码打印“Hello,World!”请不要使用java !XD我相信我是有道理的。

Java是一种混合，所以不要说它是纯粹的面向对象语言。

还有很多，但我只局限于5个XD。谢谢!

Lua

我喜欢用Lua编程，但下面是让我头疼的事情:

没有办法用这种语言编写API——不像C .h文件或Java接口 语言有一流的功能，但有人忘记告诉设计库的人。 编写函数的语法太重量级了。 语法分为语句和表达式。 表达式形式是贫乏的:没有let形式，没有真正的条件表达式，……

尽管如此，我还是坚持认为Lua非常棒:-)

PHP

没有构造函数重载 不一致的函数命名(str_replace，但strtolower) define()不像c++那样逐字替换全局变量。 在与XHTML组合时，像if-语句这样的语句必须以不缩进开始，即使为了保持XHTML缩进一致，XHTML是缩进的。

Ex:

你必须输入:

<?php
if($x == NULL)
{
?>
                     <p><?= $x . ' is null' ?></p>
<?php
}
?>

错误捕获非常糟糕

(不知道为什么又把5号改成了1号，随便了)

C是我最喜欢的，但也很糟糕。

It has the worst pre-processor ever. Why didn't they use something like m4? The whole header vs source file model is broken. Pascal got it right with units. It needs case ranges in the switch statement. Unions and casts from void* break the type system. This makes garbage collectors impossible. No nested functions. GNU C has this, but it should be standard. No boundary checking for allocated memory. There are tools that discover this but they don't detect errors where a piece of code miscalculates an address and writes to an allocated region which isn't related at all. I hate the whole pointer arithmetic. No bounds checking for arrays. Too many issues regarding portability. Even wchar_t differs across platforms.
