QUESTIONS 

SCENARIO 
Healthcare is a very important part of our lives. In this question paper we are going to  complete programs mainly aimed at doctors and patients. Medical aids are also assumed to  be a necessity.

QUESTION 1: GENERAL PROGRAMMING SKILLS 
An example of the GUI is given below: 
MED HEALTH

Complete the code for each section of QUESTION 1 as described in QUESTION 1.1  to QUESTION 1.4. 
1.1 Add the picture, Medical.jpg, as a dynamic component when the program is  executed. 

Properties: 
Left = 500 
Top = 15 
Height = 90 
Width = 120 
Stretch = True (7)

1.2 General Info Button: 
The patient must enter their title, name and surname, as well as their ID  number. The ID number must be checked to ensure it is the correct length (13  characters) and that it consists only of numbers. If the ID number is not correct,  display a suitable message. 
If the ID number is correct, a file name will be created for the patient. The file  name consists of the first three characters of the surname and a randomised  number between 100 and 999 (both included).
Display a welcome message which will include the title, initial, surname and  file name of the patient. 
Example of input: 


Example of output: 
(14)

1.3 Medical Aid Info Button 
The patient must enter their medical aid info: 

  • If the patient is the main member, (Main Member) must be displayed  next to the file name
  • If the patient has a subsidy then ‘Yes’ must be stored, else ‘No’
  • Number of dependents
  • Medical aid name 

This information must be written to text file. The text file’s name must be the  file name created in Question 1.2. 
The information must be written to the text file as follows: 

<file name>: (Main Member) 
<number of dependents> 
<medical aid name> 
<subsidy> 

Display a message once the file has been written. (13)

1.4 Update Info Button 
The information must be updated annually. Display a message which will tell  the patient when the information must be updated again. Make use of the  system date. 
Example of output: 
(5) 

  • Enter your name and surname as a comment in the first line of the program file.
  • Save your program.
  • A printout of the code may be required. 

TOTAL QUESTION 1: [39]

QUESTION 2: OBJECT-ORIENTED PROGRAMMING 

A receptionist has to manage many different tasks. Patients will want to make payments,  book the next appointment and at the end of the day the total money received must also  be recorded for financial purposes. The receptionist has to capture all the information for  the day before she leaves the office.  

Open the incomplete program in the Question 2 folder. Currently the program has no  functionality. 


Complete the code for his program as specified in QUESTION 2.1 and QUESTION 2.2. 
2.1 The given incomplete object class contains the declaration of six attributes which  describe the objRecords object. 

NAMES OF  ATTRIBUTES

DESCRIPTION

fdoctor 

Name of the doctor

fdate 

Date of doctor’s visit using the system date

fmedaid 

Yes/No indicating whether the patient has medical aid or not

ffollowup 

Whether follow-up is needed (‘Yes’ or ‘No’)

fpayment 

Cash payment made

fmed 

Amount charged to medical aid

2.1.1 Write a constructor called Create which will assign values to the fdoctor,  fdate, fmedaid, ffollowup attributes. Fpayment and fmed must be  initialised to zero. (4) 
2.1.2 Write a method called FollowUpDate which will return the date the  patient has to see the doctor again. The follow-up appointment has to be  seven days after the first appointment. If no follow-up appointment is  required then a string message must be returned indicating that no  appointment is needed. 
(Assume that the month has 30 days.) (9)
2.1.3 Write a mutator method called SetPayment which will receive the  payment that was made and update the existing payment amount. (2) 
2.1.4 Write a mutator method called SetMed which will receive the amount that  was submitted to the medical aid and update the existing medical aid  amount. (2) 
2.1.5 Write a method called CompileString which will return information about  the follow-up appointment. 
If a follow-up appointment is needed, the message should be the  following: 

Patient must please see <Doctor> on <follow-up date> 

If no follow-up appointment is needed, then the following message should  be displayed: 

No Follow-Up Appointment Needed (5) 

2.2 An incomplete class Question2U is provided.  
2.2.1 Capture Info Button 
Write code to capture all the information and use it to instantiate the  objRecords object. Call the CompileString method and display the  contents using a message box. 
The amount requested to be paid will be randomised and must be  between 300 and 400 (both amounts included). 
If the patient has a medical aid, then the amounts will be sent to the  medical aid on behalf of the patient. If the patient has no medical aid, then  the amount must be paid by the patient. 
Example of output: 
Patient has medical aid: 


Patient does not have medical aid (take note that amounts will be different  due to the amounts being randomised): 

(20)

2.2.2 Stats for the Day Button 
Write code to display the total amount of cash that was paid for the day  as well as the total amount that was charged to medical aid. All monetary  values must be formatted to two decimal places. 
Display how many patients each doctor had on that particular day. 
Example of output (output will be different as it depends how many times  the Capture Info was selected; as well as randomising of numbers): 
TSTAS(5) 

  • Enter your name and surname as a comment in the first line of the program file.
  • Save your program.
  • A printout of the code may be required. 

TOTAL QUESTION 2: [47]

QUESTION 3: PROBLEM-SOLVING PROGRAMMING 
This question will focus on the actual appointments. Two arrays have been given:  arrtimes and arrdoctors.  
3.1 When the program is executed, this should be displayed: 
PROBLEM

Write code to add the column (arrtimes) and row headings (arrdoctors). 
The current patients’ names are stored in a text file, patients.txt. Extract the  names and store them in a two-dimensional array, with class scope, called  ar2appointments. 
The layout of the text file is as shown below. 
PATIENT TXT

Make use of a method to display the names in the string grid. (21)

3.2.1 Insert Method 
Write a method called Insert which will receive the name of the patient  as well as the column (doctor’s number) as parameters. A timeslot must  be randomised. If the doctor’s number is between 1 and 4 then the patient  must be allocated to that specific doctor in a timeslot that is available. If  the doctor number is 5, then the patient can be assigned to any doctor at  random. The appointment must be added to the two-dimensional array. 
Display a suitable message whether the appointment was made or not. (17)
3.2.2 Add Appointment Button 
The patient must enter the preferred doctor’s number. Use another  Inputbox to enter the patient's name and surname. Call the Insert method  and display the updated two-dimensional array in the string grid. (4) 
3.3 Change Appointment Button 
Enter the patient’s name and surname. Find the patient’s details in the two dimensional array and then call the Insert method. The patient must see the same  doctor as their original appointment. The original appointment must be deleted in  the two-dimensional array. Display the updated two-dimensional array. (7) 
3.4 Search Button 
Search for the patient’s name and surname that was entered. Display a message  that will include the doctor who will be seen as well as the time of the appointment. (5) 
3.5 Doctor Walk-In Button 
The doctor with the least appointments on the day will be responsible for all the  patients who need to see a doctor without a prior appointment. Write code to  calculate which doctor has the least appointments and display a message  indicating the doctor's name. (10) 

  • Enter your name and surname as a comment in the first line of the program file.
  • Save your program.
  • A printout of the code may be required.
