| 摘 要： | 介绍了在C 中不通过类的接口而对其数据成员进行访问的新方法.该方法根据C 对象模型的特点,通过一个指向待访问的数据成员的指针和一个指向全局(或静态)变量的指针,分别获得待访问的auto类型数据成员指针和静态数据成员指针,从而实现了对类的数据成员的访问.该方法同时表明了类提供的保护和封装对数据成员的安全是不可靠的.

| Abstract: | In this paper,a new approach to accessing the data-members of a class in C++ is introduced.According to the C++ object model,an auto type data-member pointer and a static type data-member pointer are respectively acquired by using one pointer which points to the accessed data-members and another pointer which points to the accessed static variable.And through these two acquired pointers the data-members access is achieved.The new approach also shows that data-member protection offered by class and security from capsulation are usually unreliable. |
