What are some examples of the Strategy Pattern in C++ and Java?

The Strategy Pattern is a behavioral design pattern that enables selecting an algorithm's behavior at runtime. In C++, you can implement it using interfaces and classes, while in Java, you can use interfaces and anonymous classes or lambda expressions.

Can you give me a specific example in C++?

Sure! In C++, you might have a SortingStrategy interface with different sorting algorithms like QuickSort and BubbleSort. You can then create a Context class that uses a SortingStrategy to sort data.

And how would that look in Java?

In Java, you could define a SortingStrategy interface and implement it with classes like QuickSort and BubbleSort. The Context class would then use a SortingStrategy to perform sorting, allowing you to switch strategies at runtime.

What are the benefits of using the Strategy Pattern?

The Strategy Pattern promotes flexibility and reusability. It allows you to change algorithms without modifying the context, making your code easier to maintain and extend.
