What are some advanced design patterns in C++?

Some advanced design patterns in C++ include the Visitor, Observer, and Strategy patterns. Would you like to know more about any specific one?

Can you explain the Visitor pattern?

The Visitor pattern allows you to add new operations to existing object structures without modifying them. It involves a visitor class that implements operations on elements of an object structure.

How does it differ from the Strategy pattern?

The Strategy pattern defines a family of algorithms, encapsulates each one, and makes them interchangeable. In contrast, the Visitor pattern is more about adding new operations to existing classes without changing their structure.

Can you give an example of the Observer pattern?

Sure! The Observer pattern defines a one-to-many dependency between objects so that when one object changes state, all its dependents are notified. A common example is a news agency that notifies subscribers when news is published.
