Arduino OOP - Add some Getters and Setters

The video tutorial explains the use of getter and setter methods in object-oriented programming to access and modify private attributes. It covers the implementation of these methods, including where to place them in the code, and discusses the importance of validation. The tutorial also highlights the need for getters and setters to be public and provides examples of how to use them in a class.

What is the primary purpose of using getter and setter methods in object-oriented programming?

• To enhance the performance of the program

• To directly access private attributes from outside the class

• To provide controlled access to private attributes

• To simplify the code structure

Which naming convention is typically used for getter methods?

• Use 'fetch' followed by the attribute name

• Use 'retrieve' followed by the attribute name

• Use 'get' followed by the attribute name

• Use 'access' followed by the attribute name

What is a common practice regarding the placement of getter and setter implementations?

• Place them in the implementation file if they are complex

• Always place them in a separate file

• Place them in the header file if they are simple

• Always place them in the main file

Why might a developer choose to implement getters and setters in the header file?

• To reduce compilation time

• Because they are typically one-liners

• To improve code readability

• To enhance security

What additional step might be necessary when implementing a setter method?

• Using a different data type for the parameter

• Making the method static

• Ensuring the method is private

• Adding validation rules for the input data

What is a potential validation rule for a setter method handling a delay attribute?

• Ensure the delay is a floating-point number

• Ensure the delay is a negative value

• Ensure the delay is a string

• Ensure the delay is within a specified range

Why should getter and setter methods be public?

• To restrict access to certain users

• To enable access from outside the class

• To allow access from within the class only

• To improve the security of the class
