What is the difference between object oriented approach and procedure oriented approach?

Answer 1

Object oriented focuses on treating variables as objects that have the ability to perform certain tasks. Procedure oriented uses procedures (functions) to perform tasks on variables. For example, if you were writing a program for a DVD rental store:

Object Oriented:

thisdvd.assignTitle("Lethal Weapon");

thisdvd.rentTo("John Smith");

Procedure Oriented:

String thisdvdnumber = 123;

rentDvd(thisdvdnumber, "John Smith");

In the first case, you call functions that belong to object "thisdvd", like assignTitle(), rentTo(), etc. In the second case, you create a variable "thisdvdnumber", then call function "rentDvd()" and tell it which DVD to rent and to whom by passing those variables to it.
