Creational Design Patterns in Modern C++ - Pros and Cons - highlights the pros and cons of this pattern 1

The video tutorial explains the prototype design pattern, focusing on its use in object-oriented programming. It covers the clone method, shallow and deep copying, and serialization as an alternative. The tutorial discusses the pros and cons of the pattern, including its ability to promote loose coupling and dynamic object creation. It also provides scenarios for when to use the prototype pattern and concludes with a brief introduction to the builder design pattern.

What is the primary purpose of the 'clone' method in the prototype pattern?

• To modify the state of an object

• To delete an existing object

• To return a copy of the object

• To create a new instance of a class

How does serialization differ from the traditional prototype pattern?

• It requires a common base class

• It always creates a shallow copy

• It writes the object's state to persistent storage

• It is only available in Java

What is a potential drawback of using serialization in the prototype pattern?

• It is not supported in Java

• It involves disk IO, which may be less efficient

• It requires implementation of an interface

• It always creates a shallow copy

Which languages are mentioned as having built-in support for serialization?

• Python and Ruby

• Java and C

• Swift and Kotlin

• JavaScript and PHP

Which of the following is a benefit of using the prototype pattern?

• It is only useful in C

• It requires more memory

• It promotes loose coupling

• It increases the number of classes needed

Why might the prototype pattern be preferred over the factory method pattern?

• It avoids creating a parallel hierarchy of factories

• It requires more factories

• It is only applicable to Java

• It is less efficient

In which scenario is the prototype pattern particularly useful?

• When deleting objects

• When modifying the state of an object

• When creating a single instance of a class

• When objects have variations in state
