1. The Abstract Class Planet must include the following Properties and Methods: (24 Marks: Functionality): a. Private Instance Variables: _diameter (double), _mass (double), _moonCount (int), _name (string), _orbitalPeriod (double), _ringCount (int), _rotationPeriod (double) (7 Marks: Functionality). b. Public Properties: Diameter (Read Only), Mass (Read Only), MoonCount, Name (Read Only), OrbitalPeriod, RingCount, and RotationPeriod (7 Marks: Functionality). c. The constructor Method should take name, diameter and mass as local variables and set the related instance variables (_name, _diameter and _mass) to their values (6 Marks: Functionality). d. Override the inherited ToString() method so that it outputs Name, Diameter and Mass to the Console (4 Marks: Functionality). 2. The class GiantPlanet that is a subclass of the Planet Abstract class. The class will also implement both the IHasMoons and IHasRings interfaces: (8 Marks: Functionality): a. Private Instance Variables: _type (string) which will hold a string that describes the type of Giant Planet (either Gas or Ice) (2 Marks: Functionality) b. The constructor Method should take all the parameters of the Planet base class as well as type as a local variable and set the related instance variable (_type) to its value (2 Marks: Functionality). c. Implement the HasMoons method that will return true if the MoonCount property is greater than zero (2 Marks: Functionality). d. Implement the HasRings method that will return true if the RingCount property is greater than zero (2 Marks: Functionality). 3. The class TerrestrialPlanet that is a subclass of the Planet Abstract class. The class will also implement both the IHasMoons and IHabitable interfaces: (7 Marks: Functionality): a. Private Instance Variables: _oxygen (bool) (1 Marks: Functionality) b. The constructor Method should take all the parameters of the Planet base class as well as oxygen as a local variable and set the related instance variable (_oxygen) to its value (2 Marks: Functionality). c. Implement the HasMoons method that will return true if the MoonCount property is greater than zero (2 Marks: Functionality). d. Implement the Habitable method that will return true if the oxygen instance variable is set to true (2 Marks: Functionality). 4. The Interface IHasMoons which will include a method header HasMoons that returns a bool data type (2 Marks: Functionality). 5. The Interface IHasRings which will include a method header HasRings that returns a bool datatype (2 Marks: Functionality). 6. The Interface IHabitable which will include a method header Habitable that returns a bool data type (2 Marks: Functionality). 7. The Main method of your driver class will be structured as follows (5 Marks: Functionality): a. The Main method of your driver class (Program), implements the GiantPlanet class by creating a new giantPlanet object (1 Mark: Functionality). b. Have the giantPlanet object call its public ToString() method to display planets stats to the console (1 Mark: Functionality). c. The Main method of your driver class (Program), will also implement the TerrestrialPlanet class by creating a new terrestrialPlanet object (1 Mark: Functionality). d. Have the terrestrialPlanet object call its public ToString() method to display planets stats to the console (1 Mark: Functionality). e. Implement another Method of your driver class (Program), WaitForAnyKey, that reads the console for any key press before the console is closed (1 Mark: Functionality). 8. Program Structure (8 Marks: Program Structure): a. Your Driver class will be named Program. You will use this class to create an object instance of the GiantPlanet and TerrestrialPlanet classes (1 Mark: Program Structure). b. Your Abstract Planet class will be named Planet. This class will be contained in a separate file named Planet.cs (1 Marks: Program Structure). c. Your Giant Planet class will be named GiantPlanet. This class will be contained in a separate file named GiantPlanet.cs (1 Marks: Program Structure). d. Your Terrestrial Planet class will be named TerrestrialPlanet. This class will be contained in a separate file named TerrestrialPlanet.cs (1 Marks: Program Structure). e. You will need three interface classes for this assignment: IHasMoons, IHasRings and IHabitable. Each interface will be contained in separate files named IHasMoons.cs, IHasRings.cs and IHabitable.cs respectively (3 Marks: Program Structure). f. Ensure all private class member variables (instance variables) use an underscore character (_) at the beginning of the identifier name to signify that they are private (or protected) (1 Mark: Program Structure). 9. Include Internal Documentation for your program (6 Marks: Internal Documentation): a. Ensure you include a program header that indicates: The Author's name, Authors student number, Date last Modified, Program description, Revision History (4 Marks: Documentation). b. Ensure your program uses contextual variable names that help make the program humanreadable (2 Marks: Documentation). 10. Share your files on GitHub to demonstrate Version Control Best Practices (4 Marks: Version Control). a. Your repository must include your code and be well structured (2 Marks: Version Control). b. Your repository must include commits that demonstrate the project being updated at different stages of development each time a major change is implemented (2 Marks: Version Control). SUBMITTING YOUR WORK Your submission should include: 1. A zip archive of your project files 2. A link to your project files on GitHub. Feature Description Marks Functionality The program's deliverables are all met and the program functions as it should. No errors appear as a result of execution. User Input does not crash the program. 50 Program Structure Your main "driver" class is named Program and it creates objects that are defined in other classes. All other classes are contained in their own files. Your classes use public properties and related private member variables wherever possible. 8 Internal Documentation A program header is present and includes the name of the program, the name of the student, student number, date last modified, a short revision history and a short description of the program. All methods and classes include headers that describe their functionality and scope and follow commenting best practices. Inline comments are used to indicate code function where appropriate. Variable names are contextual wherever possible. 6 Version Control GitHub commit history demonstrating regular updates. 4 Total 68
