结构与类 [英] Structs vs. Classes
问题描述
我对结构和类之间的区别感到困惑吗？
有时候，我只想要一组字段一起去。没有方法的类
似乎是错误的，因为它带来了太多的开销（我认为是b $ b）。结构似乎更合适。至少这是我在其他语言中使用的
。但是因为一个Struct *可以*持有方法，
如果我保存任何东西我会徘徊。如果不是，为什么要使用它？
I''m really confused by the difference between a Struct and a Class?
Sometimes, I want just a group of fields to go together. A Class
without methods seems wrong, in that it carries too much overhead (I
think). A Struct seems more appropriate. At least it is what I would
have used in other languages. But since a Struct *can* hold methods,
I wander if I am saving anything. If not, why use it?
推荐答案
主要区别在于类是由参考，但结构
按值传递，如String类型。
所以类比结构更快..

Hi,
The main difference is that Classes are by reference, but the structs
are passed by value, like the String type.
So Classes are faster than Structures..

好吧，好吧。但我不得不问，什么是结构的正确使用？
我会用它而不是类吗？

Well, fine. But I have to ask, what is the proper use of a Struct?
Would I ever use it instead of a Class?

Eugh。
这取决于你在做什么。考虑一下为什么通过
值通过，作为一个极端的例子。

Eugh.
It depends on what you''re doing. Think about why ints are passed by
value, as an extreme example.
