Virtual function
Pure virtual function


A virtual function is a member function of base class which can be redefined by derived class.
A pure virtual function is a member function of base class whose only declaration is provided in base class and should be defined in derived class otherwise derived class also becomes abstract.


Classes having virtual functions are not abstract.
Base class containing pure virtual function becomes abstract.


Syntax: Virtual<func_type><name>{//Code..}
Syntax:virtual<func_type><func_name>()


Definition is given in base class.
No definition is given in base class.


Base class having virtual function can be instantiated i.e. its object can be made.
Base class having pure virtual function becomes abstract i.e. it cannot be instantiated.


If derived class do not redefine virtual function of base class, then it does not affect compilation.
If derived class do not redefine virtual function of base class, then no compilation error but

Abstracion
Encapsulation


Abstraction is a process or method of gaining the information
Encapsulation is the process or method to contain the information.


In abstraction, problems are solved at the design or interface level
In encapsulation, problem are solved at the implementation level.


Abstraction is a methods of hiding the unwanted information.
Encapsulation is a method to hide the data in a single entity or unit along with a method to protect information from outside.


we can implement abstraction using abstract class and interfaces.
Encapsulation is implementation using by access modifier i.e Private, public & protected


The objects that helps to perform abstraction are encapsulated.
Objects that result in encapsulation need not be abstracted.

compile time Polymorphism
Runtime Polymorphism


At Compile time, which functions to be called is decided.
At Runtime, which function to be called is decided.


Also known as early or static binding
Also known as late or dynamic binding


It executes faster because the function is resolved at compilation time only.
It executes slower because the function is resolved at Run-time.


It is achieved through function and operator overloading
It is achieved through function overriding and virtual functions
