The Virtual tables are contructed during compile time . The compiler
create a pointer vptr to point to the vtable during but it doesn't
contain the address of the function which is declared as virtual
because it is still not loaded in memory . Becoz is suppose to link
the modules and header files t
when the vtable of a class (if it has a virtual function ) is created
and loaded in memory
1. at the time of class declaration (before the 1st object of that
class is created)
2. when the 1st object of that class is created
3. its compiler dependent .(not specified by c++ standard)

You re
as of my knowledge ... virtual table is created for every class which has
either a virtual function or derived from a class which has virtual
function..
suppose..B is child of A , if u create an obj for A and called virtual
method overloaded in B,then the method in A only be called...
So, in ur pro
let their be two classes A and B having a virtual function.
class C derives both class A and B.
How many virtual table does class C have?
