What is the purpose of the private members `hr` and `min` in the `clockType` class?

To prevent direct access to the hour and minute values of the clock object. (correct)

To store the hour and minute values of the clock object in a static memory location.

To allow direct access to the hour and minute values of the clock object.

To provide default values for the hour and minute of the clock object.

Why are the statements `myClock.hr = 10;` and `myClock.min = yourClock.min;` considered illegal?

Because the `hr` and `min` members are declared as static in the `clockType` class.

Because the `hr` and `min` members are declared as private in the `clockType` class. (correct)

Because the `hr` and `min` members are declared as automatic in the `clockType` class.

Because the `hr` and `min` members are not declared as public in the `clockType` class.

What is the purpose of the `clockType` class in the given context?

To provide a set of functions for manipulating clock objects.

To provide a way to create static clock objects that can be shared across the program.

To provide a way to create automatic clock objects that are destroyed when they go out of scope.

To provide a data type for representing a clock object. (correct)

What is the purpose of the `public` and `private` access specifiers in the `clockType` class?
