Here is a simple explination...

Dynamic Binding enables... Polymorphism

Terminology
Poly + morphism = multiple + form
Y assumes “multiple forms”, depending on the kind of
object is points to

                                  Y
                              showIt

         showIt            showIt           showIt
    aSpreadSheet    aDocument     aGraphic

each class has its own showIt method

Dynamic binding in OO (broad sense)
1. determining the object (and its type)
2. looking for the method [aka. method lookup]

Dynamic binding and polymorphism
dynamic binding is a mechanism (different impls)
polymorphism is a design technique for improving software- requires dinamic binding.

You better refer to our MCS-024 study materials first as IGNOU questions usually come from study materials. Dynamic binding is a type of polymorphism. But there are other types of polymorphism too, like overloading and overriding. It is explained in page 39-40 of MCS-024 Block-2. The general concept of polymorphism is explained in Block-1 and also in Block-2. (Actually, although our book projects the concept that Dynamic Binding is a third type of polymorphism...its confusing whether it can be called a third type. Some textbooks do call it as a third type of polymorphism. Overriding is implemented as dynamic binding while overloading is implemented as static binding...but all these will be confusing. Try to read the IGNOU text first and then clarify your concept from reference texts) Our OOPS concepts are primarily related to Java. So some C++ concepts like multiple inheritance is not covered. Check these articles too: [URL=http://geekexplains.blogspot.com/2008/06/dynamic-binding-vs-static-binding-in.html]http://geekexplains.blogspot.com/2008/06/d...binding-in.html[/URL] [URL=http://www.geekinterview.com/question_details/57993]http://www.geekinterview.com/question_details/57993[/URL]

Hello Everyone and Santanu! These below are the two question's I have came through,in my question paper: 1)What is meant by dynamic binding? 2)Explain the concept of polymorphism. I've read that Polymorphism refers to late or dynamic binding in Kamthane C++ Textbook. Does that mean I should write same answer to this two questions? What is the difference between dynamic binding and polymorphism? Please help me with this doubt! :) :thanks: a lot!

Hello Everyone and Santanu!

These below are the two question's I have came through,in my question paper:

1)What is meant by dynamic binding?
2)Explain the concept of polymorphism.

I've read that Polymorphism refers to late or dynamic binding in Kamthane C++ Textbook.

Does that mean I should write same answer to this two questions?

What is the difference between dynamic binding and polymorphism?


Please help me with this doubt! :)

:thanks: a lot!
