Behavioral Design Patterns in C++ - Overload Pattern

The video tutorial explains the implementation of the visitor pattern in modern C, focusing on adding operations to objects within an object structure. It discusses using Lambda expressions for simple implementations and highlights the challenges of type distinction using compile-time checks. The tutorial introduces the overload pattern as an alternative approach, utilizing deduction guides to simplify the process. The video concludes with a demonstration of the implementation and its output.

What is the purpose of implementing the visitor pattern in modern C?

Explain how overloaded function call operators are used in the context of the visitor pattern.

What are the advantages of using a Lambda expression instead of creating a new class?

Describe the process of distinguishing between different types (Line, Circle, Rectangle) in the implementation.

Discuss the disadvantages of using conditional expressions to determine the type of the argument.

How does the Overload pattern improve the implementation of the visitor pattern?

What is the role of deduction guides in the context of the overload structure?
