友谊在C ++中继承吗？ [英] Is friendship inherited in C++?

问题描述

假设我有一个 Base 类：

  class Base { 
 friend SomeOtherClass; 
}; 
  

还有另外一个不同的类继承自 Base ：

  class AnotherClass：public Base {} 
   
解决方案
原则上，派生类继承基类的每个成员，除了：
  *其构造函数及其析构函数
 * ）member 
 *其朋友
  
朋友不会继承。
 
Suppose I have a Base class:
class Base {
    friend SomeOtherClass;
};
And there is another (different) class that inherits from Base:
class AnotherClass : public Base {}
Is friendship inherited as well?
解决方案
In principle, a derived class inherits every member of a base class except:
* its constructor and its destructor
* its operator=() members
* its friends
So, no. Friends are not inherited.
