The object programming in C++ can be summarized as follows:

1. class inheritance and object properties set up 
  by the compiler for all static parts and a bunch of static functors with 
  *this as the hidden parameter

2. one vtable in a class and  one vpointer in an object to be used to  
invoke the right function pointer as a virtual function  at the run-time

3. the operator reloading part similar to   smalltalk only in syntax but not very helpful  in developing cad tools or code generators
