C++ Programming Assignment 4

Patients

The objective of this assignment is to demonstrate composition in object-oriented programming. Do not try to implement this program using inheritance. That is for a later assignment.

Requirements:

You are working in a doctors office and have been tasked with creating an application to maintain Patient records for each doctor in the office.

Create a class to maintain a Doctor. A doctor has a name that must be stored in the Doctor class. A doctor can only treat 3 patients but could treat fewer than 3. The information for each patient should be encapsulated in a Patient class and should include the patients last name and up to 5 cholesterol readings for the patient. Note that less than 5 cholesterol readings may sometimes be stored. Your Doctor class should support operations to add a patient record to the end of his/her list of assigned patients (i.e., use a vector to store Patient objects in the Doctor class), and to list all patient records (name and associated cholesterol readings). Your Patient class should include operations to allow entry of the patients last name and up to 5 cholesterol readings, and to return the name and cholesterol readings for that patient.

You should write a main program that creates a single Doctor and presents a menu to users that allows them to select either Add (A), or List (L), or Quit (Q). Add should allow the user to enter a patient record (name and cholesterol readings) and add it to the end of the doctors list of patients. List should list all patient records currently in the doctors list. Remember that a patient record includes the patients name as well as his/her cholesterol readings. You should be able to add and list repeatedly, until you select Q to quit.

Use good coding style and principles for all code and input/output formatting. All data in a class must be private. Put each class declaration in its own header file and its implementation in a separate .cpp file.

How to approach this lab:

1. In main():
   1. Prompt the user to enter a name for a doctor.
   2. Create an object of the Doctor class, passing in the name of the doctor as an argument to the constructor of the Doctor class.
   3. Create a menu with cout statements.
   4. Create a switch statement that contains the cases that the user could enter.
   5. For the Add patients case, prompt the user to enter a name for the patient if the number of patients already existing is less than 3.

1. Using the Doctor object, call the function in the Doctor class to add a patient, passing in the name of the patient that the user entered.

1. 6. For the List Patients case, call the function that prints patient records, again by using the Doctor object to call the function in the Doctor class.
2. In the Doctor class:
   1. Make sure you have a constructor that initializes the Doctor name. Remember that the name is passed in from main().
   2. The Doctor class contains the function to add a Patient. In it, you will create a new Patient object (passing in the name of the patient that came from main()), and add it to the vector of Patient objects (which is a data member in the Doctor class).
   3. As soon as you create a Patient object in the Doctor class, call the function in the Patient class that allows the user to enter up to 5 cholesterol readings for that patient. Next, add that completed patient record to the vector of Patient records in the Doctor class.
   4. Include a function that will print each Patient object in the Doctor class. That is, loop over all the Patient objects in the vector and for each object, call a function in the Patient class that will print each patients record. Its like using Doctor as a middleman main() calls a function in the Doctor class to list the patients assigned to that doctor. Doctor contains the loop to iterate over each Patient object in its vector, then within the loop, each Patient object calls a function in the Patient class that will print out the names and cholesterol readings of a given Patient object.
3. In the Patient class:
   1. Make a constructor that initializes the patients name to whatever was entered in main() and subsequently passed in to your Doctor function that adds new patients. Recall that this information will be passed in to the Patient constructor from the Add Patient function in Doctor.
   2. Create a function that will allow the user to enter up to 5 cholesterol readings for a patient. This function will actually contain the cout and cin commands to prompt the user to enter each cholesterol reading. (Dont worry about putting error checks in here because I wont try to break it.)
   3. Naturally, this class will contain either an array or vector (your choice) of cholesterol readings that the user will enter (no more than 5 but could be fewer).
   4. The Patient class will contain a function that displays the cholesterol readings for a patient. It will need to loop over all the cholesterol readings in the array for the patient and print them out. This function will be called from the function in the Doctor class that prints out each Patient object.

To give you an idea of the general criteria that will be used for grading, here is a checklist that

you might find helpful:

Excutes without crashing

Appropriate Internal Documentation

Doctor class created

Doctor.h

Doctor.cpp

Contains data for no more than 3 patients

Patient class created

Patient.h

Patient.cpp

Contains data for up to 5 cholesterol readings

Menu

Add: Successfully adds a patient record

Successfully adds cholesterol readings

List: Lists all the data

Quit: Quits

Loops until the user selects quit

Style:

Data members are correctly declared

Member functions exist in the correct classes

Overall style is appropriate (no globals unless constants, modularity, uses a vector, adheres to the principle of least privilege, etc.)

Appropriate formatting of output
