Composition in C++ is a fundamental concept that allows creating modular and complex structures by combining simpler objects into larger entities, representing a 'has-a' relationship. It enables code organization, reusability, and maintainability, exemplified by structures such as houses and cars, where classes consist of various components. Through composition, developers can construct these larger systems by integrating smaller, manageable parts.

1. Topic: Composition in C++

2. 1) Composition is a fundamental concept in C++ that allows us to create modular
and complex structures.
2) It involves combining simpler objects or components to form a larger entity.
3) Composition is a powerful technique in C++ for building complex structures.
4) By combining simpler objects or components, we create modular and reusable
code.
5) Through composition, we achieve code organization, reusability, and
maintainability.
6) It represents a "has-a" relationship between classes, where one class contains an
instance of another class as a member.
7) Let's explore composition using examples from our daily lives.
Composition in C++

3. Example 1: House Composition
House
• Room
• Door
• Window
• Furniture
Explanation
 In the House class, we include objects of Room,
Door, Window and Furniture Class as Data
Members.
 This composition allows us to construct a House by
combining these elements.

4. Example 2: Car Composition
Car
• Engine
• Tire
• Steering Wheel
• Seat
Explanation
 In the Car class, we include objects of Engine, Tire,
Steering Wheel and Seat Class as Data Members.
 This composition allows us to construct a Car by
combining these elements.
