What are some advanced structural design patterns in C++ and Java?

Advanced structural design patterns include the Composite, Decorator, and Proxy patterns. Would you like to explore one in detail?

Can you explain the Decorator pattern with an example?

Sure! The Decorator pattern allows behavior to be added to individual objects, either statically or dynamically, without affecting other objects. For example, in a coffee shop application, you can have a base Coffee class and then create decorators like MilkDecorator or SugarDecorator to add functionalities.

How does the Composite pattern work?

The Composite pattern lets you compose objects into tree structures to represent part-whole hierarchies. It allows clients to treat individual objects and compositions uniformly. For instance, in a graphic application, you can have shapes that are either simple (like circles) or complex (like groups of shapes).

What are the benefits of using these patterns?

Using these patterns promotes code reusability, flexibility, and easier maintenance. They help in managing complex systems by providing clear structures.
