- 2. Various Programming Paradigms A Programming Paradigm defines the methodology of designing and implementing programs using the key features and building blocks of a programming language. Different Programming Paradigms Procedural Programming Object Based Programming Object Oriented Programming
- 3. Procedural Programming Procedural Programming lays more emphasis on procedure than data. Whenever the definition of a type changes, the functions referring to this type must also be changed to reflect the change. Procedural Programming leads to increased time and cost overheads during design changes.
- 4. Object Based Programming In Object Based Programming, data and its associated meaningful functions are enclosed in one single entity a class. Whenever there is any change in definition of type, user’s interface remains unaffected generally. It hides implementation details from user. It does not supports inheritance and polymorphism
- 5. Object Oriented Programming It is same as of object based programming. It supports inheritance and polymorphism.
- 6. OOP Concepts Object is an identifiable entity with some characteristics and behaviour. A class is a group of objects that share common properties and relationships.
- 7. Basic Concepts of OOP Data Abstraction It refers to the act of representing essential features without including the background details. Data Encapsulation Wrapping up of data and operations into a single unit. It is a way to implement data abstraction.
- 8. Modularity Property of a system that has been decomposed into a set of cohesive and loosely coupled modules. Inheritance It is the property of one class of things to inherit the capabilities or properties from another class. It implements idea of reusability.
- 9. Polymorphism Ability of a message or data to be processed in more than one form. It is a property by which same message can be sent to objects of several different classes, and each object can respond in a different way depending in its class.
- 10. Advantages of OOP Re-use of code. Ease of comprehension Closely represent the generic application concepts and processes. More near to real-world models Ease of fabrication and maintenance. Easy redesign and extension.
- 11. Disadvantages of OOP Classes tend to be over generalised. Relation among classes becomes artificial at times. OOP programs design is tricky. One needs to do proper planning and proper design for OOP Programming. Programmer need proper skills such as design skills, programming skills, thinking skills.
