Inside the C++ Object Model Stanley B. Lippman
Publisher: Addison-Wesley Professional

I'd also add the following to understand the whys and hows of C++. As a side note theres a nice discussion Stanley Lippman makes in his book "Inside the C++ Obect Model", about not placing your variables at the beginning of the Function or scope in which they're defined ( that have multiple exit branches ), and to prefer putting them where they are actually used, due to the number of extra destructor calls and other compiler augmented code necessary for the C++ object model to work as expected. Inside The C++ Object Model by Stanley B. I'm sure more detailed articles are also out there today. Inside the C++ Object Model by Lippmann. The Semantics of Constructors Chapter 3. 1,default constructor constructionA default constructor synthesiszes only when the implementation needs it.When the implementation needs it?1.1,Member class object with default constructor.1.2,B. You don't know how C++ works until you've read this cover to cover. The Semantics of Functions Chapter 5. 1 针对数组的new semantic int *p_array=new int[5]; 上述表达式只是声明了5个int 指针,并没有初始化(调用vec_new()). And peeked at everything under the hood with a debugger, just to make sure Stan's right. @xcyanx: "Inside C++ object model" book has some (but still limited) example of how it works with multiple inheritance. ȿ需要注意的是避免一个base class 指针指向一个drived class objects 所组成的数组. The Semantics of Data Chapter 4. "Inside the C++ Object Model" says that the offset of a data member in a class is always 1 more than the actual offset.
