It covers additional concepts such as association, constructors, destructors, friend functions, static members, operator overloading, templates, exception handling, file handling, and smart pointers. Each topic includes essential details and definitions relevant to understanding OOP principles and practices.

OOP’s main topics and road map

Expanded Topics of Object-Oriented Programming (OOP)

1. Classes and Objects

• Defining Classes: Creating class structures with attributes and methods.

• Creating Objects: Instantiating objects from classes.

2. Encapsulation

• Access Specifiers: Using private, protected, and public to restrict access.

• Getter and Setter Methods: Controlling access to private members.

3. Abstraction

• Abstract Classes: Defining classes with incomplete implementations.

• Interfaces: Establishing contracts for implementing classes.

4. Inheritance

• Types of Inheritance: Single, Multiple, Multilevel, Hierarchical, Hybrid.

• Base and Derived Classes: Establishing relationships between classes.

5. Polymorphism

• Compile-Time Polymorphism: Function overloading, Operator overloading.

• Run-Time Polymorphism: Virtual functions, Method overriding.

6. Association

• General Association: Objects interact without ownership.

• Aggregation: "Has-A" relationship, weak association where objects exist


independently.

• Composition: "Owns-A" relationship, strong association where child objects depend


on the parent.

• Dependency: "Uses-A" relationship, where one class depends on another temporarily.


7. Constructors and Destructors

• Constructor: Initializing objects when created.

• Destructor: Cleaning up resources when objects go out of scope.

8. Friend Functions and Classes

• Friend Function: Granting access to private members.

• Friend Class: Allowing one class to access another class’s private members.

9. Static Members

• Static Variables: Class-level shared variables.

• Static Methods: Functions associated with a class rather than instances.

10. Virtual Functions and vtables

• Virtual Functions: Enabling dynamic dispatch for polymorphism.

• Vtables: Mechanism for implementing polymorphic behavior.

11. Operator Overloading

• Customizing Operators: Overloading arithmetic, relational, and logical operators.

12. Function Overloading and Overriding

• Function Overloading: Multiple functions with the same name but different
parameters.

• Function Overriding: Redefining base class functions in derived classes.

13. Templates (Generics)

• Function Templates: Writing generic functions.

• Class Templates: Creating generic classes.

14. Exception Handling

• Error Handling: Using try, catch, and throw.

• Custom Exceptions: Defining user-defined exception classes.

15. File Handling in OOP

• Reading and Writing Files: Using file streams (ifstream, ofstream, fstream).
• Serialization: Storing and retrieving object data from files.

16. Smart Pointers

• Memory Management: Using unique_ptr, shared_ptr, and weak_ptr to manage


resources effectively.
