[…] course, a main pillar of inheritance-oriented coding is overriding and polymorphism, which allows an object toautomatically access the most descendant definition for a method, but […]

@Hesam – The answers in this StackOverflow question may answer #2: http://stackoverflow.com/questions/1825653/how-to-check-code-generated-by-c-compiler

In Visual Studio, set debug point and open disassembly.
In g++, do g++ -S to generate a .s assembly file.

Thank you, the information was great and was what I really looking for.

1- Is there a good and complete reference (i.e. Book) for this? I mean the topic of how compiler translates my code. (like when compiler sees the inheritance)
2- Is there any tool to know how the compiler translates code(for example in gcc, visual studio) and I can see what you said about objects’ memory.

This is great. I just have two questions. 1. Isn’t virtual table of tree D-G-X is actually just virtual table D-G and B-E-H-X is B-E-H (and why not)? Can somebody explain how RTTI is implemented?

@Alexander Sandler – @Alexander Sandler – The ACFX vs ACDGX problem can be solved via virtual inheritance (instead of virtual methods) according to the C++ FAQ . What do you think? Thanks for the informative article!

Excellent Tutorial with pictorial representation………
I was planning to write an article on Polymorphism. But I think this is the best article ever written.
Good Luck… Keep writing…
Let me know if you have another technical blogs.

@kapil chaudhary
There is a bug in commenting system of my web-site (wordpress). When you post some code in the comment, it gets totally screwed up. Same thing happened to your code and now I cannot see what exactly you mean by that. If you still want me to take a look at this, please send me an email.
Thanks and sorry for the inconvenience.
