这里摘录自谈话他于2014年在耶鲁大学管理学院就读.

Here is an excerpt from a talk he gave in 2014 at Yale School of Management.

我们有完美的封装.在C语言中，您所要做的就是向前声明函数和数据结构.您不必实施它们.您将在头文件中声明它们，然后在C文件中实现它们.您的用户将#include您的头文件.他们看不到您的执行情况.完美的封装.您的任何用户都无法看到您的任何数据值.他们只能看到您的功能签名.他们可以看到您数据结构的名称，但看不到您数据结构内的任何成员.绝对完美的封装.

We had perfect encapsulation. In C, all you had to do was forward declare your functions and your data structures. You didn't have to implement them. You would forward declare them in a header file, and then you would implement them in a C file. Your users would #include your header file. They could see nothing of your implementation. Perfect encapaulation. There was no way any of your users could see any of your data values. All they could see was your function signatures. They could see the names of your data structures but none of the members inside your data structures. Absolutely perfect encapsulation.
