What are the basic differences between the POP (Procedure Oriented Programming) and OOP (Object Oriented Programming)?

POP	OOP
Emphasis is given more to procedures (functions)	Emphasis is given more to data in OOP
The programming task is divided into a collection of data structures and methods or functions.	The programming task is divided into objects (consisting of data members and associated member functions)
Procedures are being separated from data being manipulated	Procedures are not separated from data, instead, procedures and data are combined together and put into a class
A piece of code uses the data to perform the specific task	The data uses the piece of code to perform the specific task
Data is moved freely from one function to another function using function parameters.	Data is hidden (using private and protected access specifiers) and can be accessed only by member functions, not by an external function.
Data is not secure in POP	Data is secure OOP due to the use of access specifiers
POP follows the top-down approach to solve the problem	OOP follows the bottom-up approach to solve the problem
As the size of the program increases the debugging becomes difficult	Irrespective of the size of the code the debugging is simple and easier in OOP.
