Answer 4

I also want to know the answer of another question related to virtual function because I know less about virtual function....
the question was
" choose the correct option "(there can be more than 1 correct ans)

1) virtual function can be constant
2) virtual function can call non virtual function
3) non virtual function can't call virtual function

please explain this if u know
I never done It correct

Answer 5

not understood exactly....but ya it was helpful
thanks for the help

Answer 6

and I didn't understand the function calling part
if there is a base class with 1 non virtual function and 1 virtual function
and a derived class with 1 virtual and 1 non virtual function
and if object of derived is created then what will be the order of calling and why?

Answer 7

virtual functions enable run time polymorphism. The run time must refer to a virtual table attached to an object instantiated from any class containing a virtual function, or any class derived from one containing the virtual. the virtual table stores the address of virtual functions on a per object basis.
is this sufficient understanding to answer the question?

Answer 8

I'm afraid it appears that another of those, "guess the question" as well as answer types has crept through.

Answer 9

Just had this question, wanted to make you all aware. Maybe get it taken down, along with whoever wrote and approved it.. ;)
