How can I implement a strategy pattern in C++ and Java?

The strategy pattern allows you to define a family of algorithms, encapsulate each one, and make them interchangeable. In C++, you can use abstract classes and inheritance, while in Java, you can use interfaces.

Can you provide a simple code example for both languages?

Sure! In C++, you might have an abstract class Strategy with derived classes like ConcreteStrategyA and ConcreteStrategyB. In Java, you would define an interface Strategy and implement it in classes like ConcreteStrategyA and ConcreteStrategyB.

What are the benefits of using the strategy pattern?

The strategy pattern promotes flexibility and reusability. It allows you to change algorithms at runtime and adhere to the Open/Closed Principle.

Are there any drawbacks to using this pattern?

Yes, it can lead to an increase in the number of classes, which may complicate the codebase. Additionally, it requires careful management of the strategy objects.
