Difference between Procedural and Object Oriented Programming

The different languages reflect the different styles of programming. Procedural programming decomposes a program into various different functional units, each of which can gather and manipulate data as needed. 

Object-oriented programming, on the other hand, decomposes a program into various different data-oriented units or other conceptual units; each unit contains data and various operations that may be performed on that data. Procedural programming forced developers to write highly interdependent code.  

 We can summarize the differences as follows :

 

• Procedural Programming

 

– top down design

– create functions to do small tasks

– communicate by parameters and return values

 

• Object Oriented Programming

 

– design and represent objects

– determine relationships between objects

– determine attributes each object has

– determine behaviors each object will respond to

– create objects and send messages to them to use or manipulate their attributes
