Creational Design Patterns in Modern C++ - Basic Implementation - Part I

The video tutorial introduces the factory method design pattern, demonstrating its use in simplifying object creation. It begins with setting up a project and creating a product hierarchy with a base class and a concrete product class. The tutorial then implements a creator class that uses these product classes. It highlights the problem of hardcoding object creation and suggests using the factory method to address this issue. The video concludes by setting the stage for implementing the factory method in the next tutorial.

What is the purpose of adding a virtual destructor in the product base class?

• To prevent the class from being inherited

• To ensure derived classes can clean up resources properly

• To make the class abstract

• To allow the class to be instantiated

What is the role of the macro used in the concrete product class?

• To create a new function

• To expand to the name of the function for logging

• To optimize the code

• To handle errors in the code

Why is it problematic to hardcode the creation of product instances in the Creator class?

• It makes the code difficult to read

• It increases the size of the code

• It can introduce bugs and break existing code

• It makes the code run slower

What is the main advantage of using a factory method?

• It simplifies the syntax of the code

• It allows for dynamic creation of objects without modifying existing code

• It ensures all objects are created in the same way

• It reduces the number of classes needed

What is the next step after identifying the need for a factory method?

• Implement the factory method

• Remove the existing code

• Add more concrete product classes

• Create a new project
