The video tutorial introduces the concept of the abstract factory pattern, explaining its purpose and how to set up a project to implement it. It covers the creation of abstract product classes and their variations for different configurations. The tutorial highlights the challenges of using products from different sets without an abstract factory, emphasizing the need for code modification. The session concludes with a preview of the next lecture, where the implementation of the abstract factory will be discussed.

What is the significance of using pure virtual functions in the abstract product classes?

What challenges arise when using products from different sets without an abstract factory?

How does the implementation of the abstract factory help in managing product instances?
