Behavioral Design Patterns in C++ - Intent

The video tutorial explains the command pattern, a design pattern that converts requests into objects, allowing for parameterization, queuing, logging, and undoable operations. It describes the roles of the invoker, command, and receiver, emphasizing the decoupling of invoker and receiver. The pattern is commonly used in UI applications to avoid tight coupling. Implementation details are discussed, highlighting the command object's role in handling requests and forwarding them to the receiver. A basic implementation example is provided.

What is the role of the Command interface in the command pattern?

How can the command object either handle part of a request or forward it to the receiver?
