Hi all What are the advantages of OOP?

For me the big advantage of OO programming is that it imposes some structure on your applications and makes it less likely that you'll make mistakes. This structure also makes it easier for you (or others) to maintain applications and to produce libraries which can be easily used or extended by other developers. More specifically: 1. Data and the methods which operate on it are welded together into objects which enables you to control access to the data and restrict the operations which can be performed on it a process known as encapsulation. The blueprint for creating objects is the class and a class can also contain shared data or methods which apply to the class as a whole not to a particular object. 2. Inheritance enables you to reuse code by deriving from an existing class and then adding the new features you need or modifying existing features. 3. Polymorphism enables a group of classes to share some functionality but to implement it in a way which is appropriate for each class. If the classes are related then polymorphism can be implemented using abstract classes or virtual methods or if they are unrelated using interfaces.
