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