Behavioral Design Patterns in C++ - Function Strategy - I

The video explores different implementations of the strategy design pattern, focusing on using functions instead of classes for simple algorithms. It discusses the Array class's print function, converting a project to a UI application, and implementing the strategy pattern with function wrappers and setter injection. The video also covers handling function calls and exceptions, and creating a function to display elements in a window.

What is the main reason for moving the print function outside the Array class?

• To adhere to the Single Responsibility Principle

• To improve performance

• To make the code more complex

• To reduce memory usage

Why might the default print implementation be unsuitable for all data types?

• It only works with integers

• It uses too much memory

• It prints elements in a single line

• It is too slow

What is the main drawback of using conditional statements to handle different output types in the Array class?

• It reduces flexibility

• It simplifies the code

• It violates the Single Responsibility Principle

• It makes the code faster

What is the primary goal of the strategy design pattern?

• To reduce the number of classes

• To improve memory management

• To define a family of algorithms and make them interchangeable

• To increase code complexity

Why does the video suggest using functions as strategies instead of classes?

• Functions are easier to debug

• The algorithms are simple and do not require state

• Classes are outdated

• Functions are more efficient

What is the purpose of using a function wrapper in the strategy design pattern implementation?

• To increase execution speed

• To allow flexibility in function signatures

• To reduce code size

• To improve error handling

What is the role of the setter injection in the strategy design pattern?

• To allow changing the printing behavior at runtime

• To increase security

• To simplify the code

• To permanently set the printing behavior
