c++ - 如果我发现此声明有任何异常(exception)情况，请告诉我

Question

经过一些实验，我知道了一些事情，我想概括如下:

The member functions of an instance of a user defined class can not only access its own private data members, but also the private data members of other instances of the same class passed to them as arguments.

请告诉我这是否适用于所有情况。

Answer 1

是的，没错。这称为“同级访问”。更一般地说，类的私有(private)成员函数可以访问同一类的任何实例的私有(private)数据成员，前提是它可以访问该类型的变量。

希望这对您有所帮助!
