Characteristics of Object-Oriented Programming( OOP ) and Procedure Oriented Programming ( POP )

	Procedure Oriented Programming	Object-Oriented Programming
Divided Into	In POP, the program is divided into small parts called functions.	In OOP, the program is divided into parts called objects.
Importance	In POP, Importance is not given to data but to functions as well  the sequence of actions to be done.	In OOP, Importance is given to the data rather than procedures or functions because it works in the real world.
Importance	In POP, Importance is not given to functions.	In OOP, Importance is given to the data.
Approach	POP follows a Top-Down approach.	OOP follows the Bottom-Up approach.
Access Specifiers	POP does not have any access specifier.	OOP has access specifiers named Public, Private, Protected, etc.
Data Moving	In POP, Data can move freely from function to function in the system.	In OOP, objects can communicate with each other and pass data through member functions.
Expansion	Adding new data and functions in POP is not so easy.	OOP provides an easy way to add new data and functions.
Data Access	In POP, the Most function uses Global data for sharing that can be accessed freely from function to function in the system.	In OOP, data can not move easily from function to function, it can be kept public or private so we can control the access of data.
Data Hiding	POP does not have any proper way for hiding data so it is less secure.	OOP provides Data Hiding so provides more security.
Examples	Examples of POP are C, VB, FORTRAN, Pascal.	Examples of OOP are C++, JAVA, VB.NET, C#.NET.
