Behavioral Design Patterns in C++ - Pros and Cons-Strategy Pattern

The video tutorial discusses the strategy design pattern, highlighting its pros and cons. The strategy pattern allows for a family of algorithms to be reused by the context, promoting composition over inheritance. It is an alternative to conditional statements and helps in adding new algorithms without modifying existing code. However, it increases the number of classes and may expose implementation details. The video also covers when to use the strategy pattern and its implementation in C++, including dynamic and static strategies.

What is one of the main advantages of using the strategy design pattern?

• It provides a family of algorithms that can be reused by the context.

• It allows for the use of multiple inheritance.

• It eliminates the need for any conditional statements.

• It reduces the number of classes in an application.

What is a potential downside of applying the strategy pattern?

• It increases the number of classes in the application.

• It makes the code less modular.

• It requires the use of global variables.

• It forces the use of only one algorithm.

Why might clients be exposed to implementation details when using the strategy pattern?

• Because it involves complex mathematical computations.

• Because the pattern requires direct access to private variables.

• Because they need to understand how different strategies differ.

• Because it mandates the use of a specific programming language.

In which programming language is the strategy pattern particularly versatile due to its features?

• C++

• JavaScript

• Java

• Python

Which of the following is NOT a way to implement a strategy in C++?

• Using a lambda expression

• Using a global variable

• Using a member function

• Using a functor
