Structural Design Patterns in Modern C++ - Handle-Body

What is the primary advantage of using the Bridge design pattern?

• It allows for a single implementation of an abstraction.

• It enables abstraction and implementation to vary independently.

• It simplifies the code by reducing the number of classes.

• It ensures a one-to-one relationship between abstraction and implementation.

Which of the following is NOT an alternate name for the handle body idiom?

• Singleton

• D Pointer

• Opaque Pointer

• Cheshire Cat

What is the most common alias for the handle body idiom?

• Pimple

• Cheshire Cat

• D Pointer

• Opaque Pointer

How does Pimple help in managing changes to the implementation class?

• By exposing all implementation details to clients.

• By preventing changes from affecting multiple source files.

• By simplifying the implementation class.

• By allowing direct access to the implementation class.

What additional benefit does Pimple provide besides hiding complex details?

• It reduces the need for abstraction.

• It implements extra functionality for the implementation class.

• It allows for multiple inheritance.

• It increases the number of source files.
