为什么在C ++中默认情况下数据成员是私有的？ [英] Why are data members private by default in C++?

问题描述

在C ++中，类中的所有数据成员默认情况下是否都是私有的？

Is there any particular reason that all data members in a class are private by default in C++?

推荐答案

因为更好被正确封装，只打开需要的东西，而不是默认打开所有东西，而不得不关闭它。

Because it's better to be properly encapsulated and only open up the things that are needed, as opposed to having everything open by default and having to close it.

封装（信息隐藏）是一种好，并像安全性（例如，锁定网络服务）一样，默认值应该是好，而不是坏。

Encapsulation (information hiding) is a good thing and, like security (for example, the locking down of network services), the default should be towards good rather than bad.
