Answer / maria alex

An abstract class holds both method prototpypes and method
definitions also...But it is not in the case of
interface..It can contain only protypes.. It should be
defined only where it is implemented...

Answer / abhijit

Abstract base classes can have data members but not interfaces.

Abstract base classes have private access specifier by
default while that of interfaces is public

Answer / porchelvi .a

ABTRACT CLASS:
-------------
• It can not be instantiated

• It allow us to specify all access modifier except
Private

• A class inheriting this must implement all of its
abstract method


• A class can inherit only one abstract class at a
time.

• Abstract class can add more functionality with out
destroying child classes that were using old version.


• We can declare the following
1. Fields
2. Constructors
3. Static Constructors
4. Static Functions
5. Concrete Functions

INTERFACE :
---------

• It can not be instantiated

• It allows only public Access modifier

• A class implementing interface must provide body
for its entire member.



• A class can implement more than one interface at a
time.

• Adding of additional functionality will have an
effect on its child class due to the necessary
implementation of interface methods.

• We can not declare the following
1. Fields
2. Constructors
3. Static Constructors
4. Static Functions
5. Concrete Functions

Answer / rck

Abstract class is the class which may contain pure virtual
functions as well as normal functions where as interface
may only contain pure virtual functions.

Answer / kanan

Abstract class: You can inherit only one class.
Interface: You can inherit more than one interface.

Abstract class: It contains both completed and uncompleted
(abstract) methods.
Interface: It only contains uncompleted methods (methods
without body).

Abstract class: Access modifiers are there for methods and
properties.
Interface: It does not have access modifier for methods or
properties. By default they are public.

Abstract class: Fast
Interface: Require more time to find actual method in classes.

Abstract class: It can contain fields and constants.
Interface: no fields can be defining in interface.
