再给c++投一票…仍然是我最喜欢的语言，有几个亲密的追随者——C和Python。以下是我目前最讨厌的名单，排名不分先后:

Plethora of integer types inherited from C - way too many problems caused by signed vs. unsigned mistakes Copy constructors and assignment operators - why can't the compiler create one from the other automatically? Variable argument madness - va_list just doesn't work with objects and I'm so sick of problems created with sprintf(), snprintf(), vsnprintf(), and all of their relatives. Template implementation is required to be fully visible at compile time - I'm thinking of the lack of "export" implementations or at least usable ones Lack of support for properties - I want to have a read-only member like "a.x" that can be read publicly and only assigned internally. I really hate the "val=obj.getX()" and "obj.setX(val)". I really want properties with access control and a consistent syntax.

我自己最讨厌c++的5个地方:

自动生成构造函数、析构函数和赋值操作符。伙计，每当我在课上没有声明什么东西时，这意味着我不需要它，而不是我忘记了。你们这些编辑们，听到了吗?!

[4]模板语法。哦，我真的需要输入所有这些“<”和“>”，每当我决定从类主体提取定义?

[3]字符串。天啊，我受够了“const char*”，我必须处理NULL情况，我必须浪费O(N)来获得它的长度，我必须为concat操作分配缓冲区。

[2] Macroprocessing。每当我不明白，什么是我的编译器，我开始寻找宏。

[1]操作符重载。我看到代码“A + B * C”，在我看到A、B和C的实际类型之前，我说不出这个代码是关于什么的。

Python:

Too slow! list operations don't return the list, so you can't do list.append(4).append(5). (I mean a reference to the same list, not a copy). This is a minor gripe; it's only come up a few times. statements don't return values (if, print, while, for, etc). This is only a problem when dealing with lambdas. lambdas can only be one expression. There's no real need for this restriction, as they are equivalent to functions in every other way. What if I want a button press event which calls two functions? I'd need to create a named function to supply that functionality to an action listener, while doing "lambda: f1(); f2()" would not hurt. you can only put standard a-zA-Z_0-9 as names. Having functions like "true?" and "+" would be great. Of course, this could lead to terrible obfuscation, but I'm not saying we immediately rename all functions to "p@$%3". Which do you find clearer to read: "dec2bin" or "dec->bin"? ("store_results" or "storeResults") or "store-results"?

我可以为Python添加另一个:

给定一个列表l = [l1, l2，…]， ln]，那么repr(l) = [repr(l1)， repr(l2)，…， repr(ln)]，但str(l) != [str(l1)， str(l2)，…， str(ln)] (str(l) = repr(l))。之所以这样做，是因为列表中可能有模糊的条目，如l = ["foo]， [bar，"， "]，["]， str(l)将返回"[foo]， [bar，]，[]"，这“可能会使用户感到困惑”。然而，这使得str不可能仅用于转储数据，因为list杀死了“仅以可读格式转储数据”。Augh !

C++:

缺乏象征意义。 过度迷恋C语言的兼容性。 极其复杂的预处理器。 模板错误几乎是不可理解的。 没有垃圾回收。

Python:

速度 静态分析(缺乏) 匿名函数仅限于一个表达式
