类型与类 [英] Type versus Class

问题描述

我总是使用class这个词。描述一个可以实例化的类。

然而，我没有得到类型的概念。或者至少我不知道如何使用这个词来正确使用这个词。如果我有一个名为Person的类，它的类型是什么？

以及它与课程有什么关系？


提前谢谢。

I always use the word "class" to describe a class that can be instantiated.
However, I don''t get the concept of "Type" or at least I don''t know how to
use the word properly. If I have a class called Person, what is its "Type"
and how does it relate to the class?

Thanks in advance.

推荐答案

大多数情况下，class特别指的是引用类型，而类型

指的是引用类型和值类型

所以这意味着我也可以谈论我的人物类型，只是

查看我之前的Person class？的措辞。我希望两者之间有更多的确切差异...


再次感谢。

So this means I could just as well talk about my "Person type", and just
chuck my previous wording of "Person class?" I''m hoping there is a more
precise difference between the two ...

Thanks again.

是什么？它与该类有什么关系？

and how does it relate to the class?

类是一个模板，用于定义

类型的成员和操作。


....如果有帮助的话！ :)

A class is a template that defines the members and operations of a
type.

....if that helps! :)
