The video tutorial explains the Composite design pattern, starting with an introduction and moving through the implementation of base and leaf clauses. It covers adding composite clauses, using vectors for data structure, and implementing remove algorithms with namespace considerations. Helper code is added to understand output, and a main function is created to demonstrate the composite structure. The tutorial concludes with a class diagram explanation and a summary of the composite design pattern's structure.

What is the role of the 'operation' method in the Composite design pattern?

How does the implementation of the Composite design pattern allow for the creation of tree-like structures?

What are the potential drawbacks of using global variables in the implementation of the Composite design pattern?
