Behavioral Design Patterns in C++ - Basic Implementation - I

This lecture covers the basic implementation of the command design pattern. It starts with an overview of the pattern and proceeds to implement the receiver and invoker classes. The lecture emphasizes avoiding tight coupling between these classes by using a command interface. The implementation is tested, and the class diagram is explained to show how the invoker can execute methods on the receiver without knowing its details, allowing for flexibility and change at runtime.

What is the first clause that the teacher plans to implement in the command design pattern?

Explain the purpose of the command class in the command design pattern.

What is the significance of the execute method in the command pattern?

How does the invoker interact with the command pointer?

Describe the relationship between the invoker and the receiver in the command design pattern.

What are the advantages of using the command design pattern in terms of coupling?

How can the command design pattern allow for changing the receiver at runtime?
