contains the virtual function address.C + + compiler should be to ensure that pointers to virtual function tables exist in the first place in the object instance (this is to ensure the highest performance of the virtual function table-assuming there are multiple layers of inheritance or multiple inheritance). This means that we get this virtual function table from the address of the object instance. You c

I. Virtual function tableWhy is it feasible to use the pure abstract base class of C ++ to implement the COM interface? This is mainly because the memory structure defined in the pure abstract class can meet the interface requirements of COM. When defining a pure abstract base class, it actually defines the structure

I recently reviewed the data structure and saw this part of the Single-chain table. Most of the teaching materials used now are the C language version of Yan Weimin. I have referenced some books, manually compiled the implementation of the c ++ order linked list class. The environment is Visual Studio 2010, and the fun

Based on the one-way chain linear table http://blog.csdn.net/shiwazone/article/details/47000191, the circular linked list is implemented, and the circular linked list points the pointer field of the tail node to the head node. Join the loop, you can let us in the search for a node of the index, we can first determine the position and the link table length of the relationship, if index in the first half of t

the process of change. Many of the considerations look fine, such as the annotation style of the code (choosing our usual annotation style or the Doxygen annotation style, and the annotation style in the Code encyclopedia. Whether it needs to be borrowed); The Code naming conventions (Hungarian nomenclature or java,c# nomenclature, and many naming conventions for open source projects), whether the policy classes can be applied to the library in the n
