Add some Getters and Setters

The video tutorial explains the use of getters and setters 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, specifically in the context of an LED blinker project.

Why are getter and setter methods used in object-oriented programming?

• To directly access private attributes from outside the class

• To modify and access private attributes safely

• To increase the speed of the program

• To reduce the size of the code

What is the standard naming convention for a getter method?

• Use 'fetch' followed by the attribute name

• Use 'access' followed by the attribute name

• Use 'retrieve' followed by the attribute name

• Use 'get' followed by the attribute name

What type should a getter method return?

• The type of the class

• Always a string

• Always an integer

• The type of the attribute it accesses

Where can getter and setter methods be implemented according to the discussion?

• Either in the header or implementation file

• Only in the implementation file

• Only in the header file

• In a separate file

What is a potential additional step when implementing a setter method?

• Adding a print statement

• Validating the input data

• Changing the data type

• Ignoring the input data

What is a reason for keeping getter and setter methods public?

• To make the class abstract

• To hide the implementation details

• To enable external access to private attributes

• To allow internal access only

What is an example of a rule you might add to a setter method?

• Converting the value to a string

• Ignoring the value if it's negative

• Ensuring the value is always zero

• Checking if the value is within a specific range
