Hello Im working on an assignment that tests inheritance and

Hello. I\'m working on an assignment that tests inheritance and composition but I\'m still learning so I\'m having trouble. I will provide the code I have so far.. The class i need help creating is going to be a patient class. \"Design the class Patient, inherited from the class Person, with additional data members to store a patient’s ID, age, date of birth, attending physician, the date when the patient was admitted in the hospital, and the date when the patient was discharged from the hospital. Therefore, the Patient IS-A Person and HAS-A Doctor and several Dates (i.e., date of birth, admit date, discharge date). You should use the class Date to store the date of birth, admit date, discharge date, and the class Doctor to store the attending physician. Add appropriate constructors and methods to initialize, access, and manipulate data members.\" Thank you for the help! I\'m still learning so if you don\'t mind leaving documentation comments so I can follow the code, it would be a huge help. Thanks again.
