C++对象模型在内存中的实现，讲述了类，继承以及虚继承的内存布局；成员变量和成员函数的访问已经访问时的开销情况，包含虚函数的情况，考察构造函数，析构函数，以及特殊的赋值操作符成员函数是如何工作的，数组是如何动态构造和销毁的；简单地介绍对异常处理的支持。-C++ Object Model in memory, about classes, inheritance and virtual inheritance memory layout　overhead circumstances access member variables and member functions have access to, the condition that contains virtual functions, examining constructors, destructors, and how special assignment operator member functions work, how dynamic arrays are constructed and destroyed　simply introduce support for exception handling.
