在 C++ 中继承私有成员

Inheriting private members in C++(在 C++ 中继承私有成员)
本文介绍了在 C++ 中继承私有成员的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着跟版网的小编来一起学习吧!

问题描述

假设一个类有私有数据成员,但 setter 和 getter 在公共范围内.如果您从这个类继承,您仍然可以调用这些 setter 和 getter —— 允许访问基类中的私有数据成员.这怎么可能,因为提到派生类不能继承私有数据成员

suppose a class has private data members but the setters and getters are in public scope. If you inherit from this class, you can still call those setters and getters -- enabling access to the private data members in the base class. How is this possible since it is mentioned that a derived class cannot inherit private data members

推荐答案

派生类不继承对私有数据成员的访问.但是,它确实继承了一个完整的父对象,其中包含该类声明的所有私有成员.

A derived class doesn't inherit access to private data members. However, it does inherit a full parent object, which contains any private members which that class declares.
