Polymorphism

Question

So... what is the difference between "Virtual", "Abstract" and "Interface"?
Although they seem different in definition, but they all carry the same purpose(As I understood).
So why defining three, when one of them does the same work as the other? 🤔

Answer 1

In interface u put abstract keywords without specifiing them to be abstrac 'cuz they are automatically set ....and the difference betwen virtual and abstract is that in abstract u do not have to pre-define keyword ...both of them work almost the same way... if i remmember correctly

Answer 2

yea they are same,... thank you
