$61.$ What are structural design patterns, and how do they differ from other types of design patterns?

$62.$ Can you describe a scenario where you might use the Adapter pattern to make two incompatible interfaces work together?

$63.$ Discuss the benefits and drawbacks of using the Bridge pattern to decouple abstraction from implementation.

$64.$ In what situations would you choose the Composite pattern over other structural patterns like Decorator or Proxy?

$65.$ Explain the concept of "structural transparency" in the context of the Proxy pattern.

$66.$ Describe a real$-$world example where you might use the Decorator pattern to add new functionality to an object dynamically.

$67.$ How does the Flyweight pattern optimize memory usage by sharing objects?

$68.$ Can you identify any potential pitfalls or misuse of the Composite pattern in software development?

$69.$ Discuss the role of the Facade pattern in simplifying complex subsystems and providing a unified interface.

$70.$ How does the Proxy pattern support lazy initialization and on$-$demand loading of resources?

$71.$ Explain the concept of "double dispatch" in the context of the Visitor pattern.

$72.$ Describe a scenario where you might use the Private Class Data pattern to encapsulate data within a class.

$73.$ Discuss the implications of using structural design patterns on the scalability and maintainability of an application.

$74.$ Can you think of any alternative approaches to achieving code reuse and flexibility without using structural design patterns?

$75.$ How does the Composite pattern facilitate the creation of recursive structures of objects?

$76.$ Explain the concept of "circular dependency" and how it can be avoided when using the Composite pattern.

$77.$ Describe a scenario where you might use the Proxy pattern to control access to a sensitive resource.
