Structural or Procedural Programming Vs Object Oriented Programming

Structural or Procedural Programming	Object Oriented Programming
The principle ideas behind structural programming are as simple as the idea of divide and conquer.	An object-oriented program may be viewed as a collection of interacting objects.
It is not a successful approach for dealing with complex problems.	It is a successful approach for dealing with complex problems.
Focus is on algorithm and control flow.	Focus is on object model.
Structured programming language can view data and function as separate entities.	Object oriented language view as data and functions as single entity by using class feature.
Top-to-Bottom approach is used.	Bottom-Up approach is used.
It splits the task into modular forms. This makes the program simpler and easier to read with less lines and codes.	It splits the program into objects that can be reused into other programs.
Functions are dependent and hence reusability is not possible.	Functions are independent and hence reusability is possible.
It is more concerned with the processing of procedures and functions.	It is concerned to develop an application based on real time.
In this approach data is not hidden from the external environment.	In this approach data is encapsulated (hidden) from the external environment.
In this most functions share global data i.e. data move freely around the system from function to function.	In this mostly the data is private and only functions inside the object can access the data.
There is no access specifier.	There are public, private and protected access specifiers.
Operators cannot be overloaded.	Operators can be overloaded.
It simply passes values to the functions.	The objects communicate with each other via message passing.
It is simply traditional way of calling functions and returning values.	It includes inheritance, encapsulation and data abstraction, late binding, polymorphism and message passing.
Examples of structural programming language include C, Pearl, BASIC etc.	Examples of object programming language includes C++, Java, VB.NET etc.
