Difference Between OOP and POP 

PROCEDURE ORIENTED  PROGRAMMING(POP)	OBJECT ORIENTED PROGRAMMING(OOP)
Top down approach in program design.	Bottom up approach in program design.
No access specifiers are used. Example: In structure all the members are public.	Public,Private,protected Access specifiers are used. Example:In classData is Private and Functions are public.
Larger programs are divided into Functions.	Larger programs are divided into entites known as objects.
Most of the Functions share global data means data move openly around the system from one Function to another Function.	Data is private and Functions inside class can only access the private data.
Example of POP is C, FORTRAN.	Example of OOP is C++.
In POP operator can not be overloaded.	In OOP operator can be overloaded by using the concept of operator overloading.
Emphasis on doing algorithm means importance is given to the sequence of things to be done i.e algorithm.	Importance is given to the data.
Objects are very difficult to add in POP.	Objects ( i.e data and Functions ) are very easy to add at any time whenever necessary.
Procedural in nature.	Non-Procedural in nature.
