Answer / chandra
Vtable consists of function pointers pointing to the
virtual functions of their respective class.
Ex: Class A
{
public:
virtual void fun1();
virtual void fun2();
};
Class B: public A
{
public:
Virtual void fun2();
};
Now there will be 2 vtables created for the 2 classes. in
first vtable there will be 2 function pointers pointing to
fun1 and fun2.
one more vtable is created for the class B. in which this
vtable also consists of two function pointers because class
B is derived from class A. so all the functions are
derived . so in this vtable two function pointers are
present. one function pointer pointing to fun1 and one more
function pointer pointing to fun2 of derived class.

difference between abstraction and encapsulation with progarammatic eg. hi,just recently i went for an interview .The interviewer asked what is the difference between abstraction and encapsulation with programmatic eg. I gave the answer as encapsulation mean hiding the relevant data which is not useful for the user, eg a electric fan .hiding the information how the electricity is converted into machanical energy. abtraction showing only the relevant data to the user eg electric fan. it look ,its color ,it design etc only relevant data. Then the interviewer asked me, give me some programmic eg .I Said Let assume a web form having control like textbox,button etc. The user can view textbox,button etc this is the eg of abstraction and when the user click on the button how he is redirected is not known by the user is the eg of the encapsulation. Am I Correct .was the answer given by me is perfect .now i am planing to go for an another interview should i give the same answer.IF not please suggest me a better answer.with some good eg Please help
