virtual function

[sunny3]

Answer plz..........In C++ application virtual function is used. Assume if C++ stops supporting virtual functions, what changes need to be made in the application?

Well, what would change in your application if virtual didn't work? Obviously, the first step would be to remove the 'virtual' keyword from your files, but what next? How could you gain back the functionality of virtual without actually using virtual?

Hi buddy,
Obviously we need to change the virtual keyword first. But how we can achieve the Run time polymrphism is to use Function pointers in C Style.
I think this may work.Im not sure...

Virtual functions are part of the ANSI C++ language and cannot be removed.

Conside that of you remove the virtual keyword you could also remove any, or all, of the keywords. The result would be not usable.

Actually, that isn't that hard. You just need to decide whether to spend your life creating a personal system as opposed to using one that's already been automated and has been established as a ANSI standard.
