Structural Design Patterns in Modern C++ - Introduction to the Adapter Pattern

The video tutorial explains the adapter design pattern, which is used to convert incompatible interfaces into compatible ones. It discusses two main types of adapter patterns: object adapter and class adapter. The object adapter uses composition to achieve interface compatibility, while the class adapter uses inheritance. The tutorial highlights the purpose of the adapter pattern in enabling the reuse of existing components without modifying their source code, and it provides a brief overview of how to implement these patterns in code.

Why might you need to use an adapter in your application?

• To convert an incompatible interface into a compatible one

• To delete unnecessary components

• To create a new component from scratch

• To modify the source code of a component

What is the primary intent of the Adapter Design Pattern?

• To enhance the performance of a class

• To add new features to a class

• To convert the interface of a class into another interface that clients expect

• To simplify the code structure

Which of the following is true about the object adapter?

• It composes the adaptee and calls its methods through a reference

• It uses inheritance to implement the adapter

• It directly inherits from both the target and adaptee

• It modifies the adaptee's source code

How does a class adapter differ from an object adapter?

• A class adapter uses composition, while an object adapter uses inheritance

• A class adapter modifies the adaptee's source code

• A class adapter inherits from both the target and adaptee

• A class adapter does not convert interfaces

What additional functionality might an adapter perform besides interface conversion?

• It can create a new interface from scratch

• It can modify the adaptee's source code

• It can delete unnecessary methods from the adaptee

• It can perform checks on data passed to the adaptee
