Behavioral Design Patterns in C++ - Basic Example-1

The video tutorial explains the Strategy design pattern, starting with an introduction and the creation of a Strategy interface with a pure virtual function. It then covers the implementation of the context clause, which uses a pointer to the strategy and a method called context interface. The tutorial discusses setting concrete strategies through constructors or setter methods, and demonstrates the implementation of these methods. It shows how to create concrete strategies and use them at runtime, highlighting the dynamic nature of strategies. The tutorial concludes with a class diagram illustrating the loose coupling between the context and strategies, allowing for future extensions.

How can strategies be set in the context class, and what are the implications of each method?

What does the class diagram of the Strategy pattern illustrate about the relationship between context and strategies?

Summarize the key points of the Strategy design pattern as discussed in the lecture.
