The document discusses the differences between procedural and object-oriented programming (OOP), highlighting that OOP focuses on 'objects' that encapsulate data and methods, enabling abstraction, encapsulation, and reusability of code. It outlines key OOP concepts such as classes, inheritance, and access modifiers (public, private, protected), emphasizing the benefits of code reuse and easier maintenance. Abstract classes and the role of getters and setters in data protection are also explained, showcasing their importance in modern software development.

- 2. - Procedural Programming -Focus on processes or actions that a program takes - Programs are typically a collection of functions - Data is declared separately - Data is passed as arguments into functions As Programs get larger they become more: Difficult to understand Difficult to maintain Difficult to extend Difficult to debug Difficult to code

- 4. Object Oriented Programming Object-oriented programming(OOP) is a programming paradigm based on the concept of "objects", which can contain data and code: data in the form of fields (often known as attributes or properties), and code, in the form of procedures (often known as methods). - Encapsulation - Objects contain data and operations that work on that data - Abstract Data Type ( ADT)

- 9. Object Oriented Programming - Information- Hiding - Encapsulation - Implementation - specific logic be hidden - User of class code to be interface since they don’t need to know the implementation - More abstraction - Easier to test, debug, maintain and extend
- 10. Object Oriented Programming - Reusability -Easier to reuse classes in order application - Faster development - Higher quality
- 11. 09:Object Oriented Programmingprovide code reuse Code reuse is the practice of using existing code for a new function or software. This saves time, improves the features in your program, and generally makes for more cost-effective programming. Reusability is an important issue in software engineering.
- 12. Object Oriented Programming - Inheritance -Can create new classes in term of existing classes - Reusability - Polymorphic classes

- 15. 09:Object Oriented Programming Aclass is an extensible program-code-template for creating objects, although a very tiny application might need just a single class. The class must go within a pair of curly braces.

- 26. Accessing Class Wecan access - Class attributes - Class methods Some class members will not be accessible (more on that later) We need an object to access instance variables
- 27. Class Access Modifier -public , private and protected - public - Accessible everywhere - private - Accessible only by members or friends of the class - protected - Used with inheritance - we’ll talk about it in the next section

- 32. What are settersand getters? Getters and setters are used to protect your data, particularly when creating classes. For each instance variable, a getter method returns its value while a setter method sets or updates its value. Given this, getters and setters are also known as accessors and mutators, respectively.
- 33. What is aabstract? By definition, an abstract class in C++ is a class that has at least one pure virtual function (i.e., a function that has no definition).
- 34. What is aC++ abstract class? By definition, an abstract class in C++ is a class that has at least one pure virtual function (i.e., a function that has no definition).
- 35. What is aC++ abstract class? Abstract classes are essential to providing an abstraction to the code to make it reusable and extendable. For example, a Vehicle parent class with Truck and Motorbike inheriting from it is an abstraction that easily allows more vehicles to be added. However, even though all vehicles have wheels, not all vehicles have the same number of wheels – this is where a pure virtual function is needed.
