Object-Oriented Programming (OOP) in C++
Object-Oriented Programming (OOP) is the industry-standard paradigm for building modular, scalable, and maintainable software. By leveraging classes and objects, C++ enables developers to model real-world entities, transforming abstract data into intuitive and reusable code structures.
This module is designed to guide you through the foundational architecture of modern applications. You will move beyond simple variable storage to master data integrity through encapsulation and code extensibility through class hierarchies.
Mastery Roadmap: The 4 Pillars
Encapsulation:
Protecting internal states using private access modifiers and public interfaces.Inheritance:
Establishing "is-a" relationships to share logic across specialized classes.Polymorphism:
Redefining behavior in derived classes for dynamic, flexible execution.Abstraction:
Hiding complex implementation details to focus on essential functionality.Object-Oriented Programming Challenges
| OOP Challenge | Technical Goal & Skill Acquired |
|---|---|
| Person Class | Understand class definitions, attribute assignment, and basic member functions. |
| Circle Class | Implement mathematical behaviors inside methods using private radius data. |
| Rectangle Class | Practice object instantiation and managing multiple state variables. |
| Student Class | Master Getters & Setters to implement controlled access to private members. |
| BankAccount Class | Learn data protection by simulating secure deposit and withdrawal logic. |
| Animal Inheritance | Implement Base and Derived classes to understand code reuse and hierarchies. |
| Employee Class | Model corporate data using logic-driven methods for salary processing. |
| Inventory System | Design inter-class interactions to manage products and transaction logic. |
| Vehicle Class | Practice behavioral state management (start, drive, brake) using objects. |
| Book Class | Encapsulate multiple data types into a single coherent entity for library systems. |
