Structural Design Patterns in Modern C++ - Basic Example - Adapter Design Pattern

The video tutorial explains how to implement the Adapter design pattern through a practical example. It covers creating a solution and adding a project based on the pattern's structure. The tutorial introduces the target interface and demonstrates how the client uses it. It then explains creating an Adaptee component with an incompatible interface and how to use an Object Adapter to bridge the gap using composition. Finally, it covers implementing a Class Adapter using inheritance, highlighting the purpose of adapters in converting incompatible interfaces to work together.

What is the primary role of the target interface in the adapter pattern?

• To directly execute client requests

• To replace the client in the pattern

• To store data for the client

• To provide a method for the client to call

Why is an adaptee class necessary in the adapter pattern?

• It acts as a backup for the target interface

• It provides the functionality that the client needs but with an incompatible interface

• It replaces the target interface

• It simplifies the client code

How does the object adapter use the adaptee's functionality?

• By creating an instance of the adaptee and using composition

• By ignoring the adaptee's methods

• By directly modifying the adaptee

• By inheriting from the adaptee

What is a key difference between the object adapter and the class adapter?

• The class adapter directly inherits from the adaptee, while the object adapter uses composition

• The class adapter uses composition, while the object adapter uses inheritance

• The class adapter is more complex than the object adapter

• The class adapter modifies the adaptee, while the object adapter does not

What is the main purpose of the adapter pattern?

• To replace the target interface

• To simplify the client code

• To enhance the performance of the client

• To convert an incompatible interface into a compatible one
