Creational Design Patterns in Modern C++ - Basic Example - demonstrates how to implement the prototype pattern

The video tutorial introduces the prototype design pattern, explaining the need for a base class with a clone method that subclasses implement. It demonstrates creating concrete prototypes and a client that interacts with these prototypes. The tutorial highlights the importance of proper memory management when cloning objects, suggesting the use of smart pointers. The video concludes with a discussion on the structure of the prototype pattern and a preview of the next lecture.

What is the primary role of the base class in the prototype design pattern?

• To define a method for cloning

• To implement the clone method

• To manage memory allocation

• To store data for the prototypes

How does the client class interact with prototypes in the prototype pattern?

• By directly modifying the prototypes

• By deleting the prototypes

• By creating new prototypes from scratch

• By using a pointer to the prototype and cloning it

What message is printed when a clone is created in the client class?

• Clone creation failed

• Prototype cloning successful

• New prototype instance

• Concrete prototype cloning

Why is it important to manage memory when using the prototype pattern?

• To ensure prototypes are not duplicated

• To reduce the size of the prototypes

• To increase the speed of cloning

• To prevent memory leaks from undestroyed clones

What is one suggested method for properly destroying cloned objects?

• Using a garbage collector

• Manually deleting instances

• Increasing memory allocation

• Avoiding the use of the clone method
