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: 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). Copyright reserved Please turn over

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.

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 DESCRIPTION ATTRIBUTES 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) Copyright reserved Please turn over

(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) Copyright reserved Please turn over

Two arrays have been given: arrtimes and arrdoctors. 3.1 When the program is executed, this should be displayed: 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. Make use of a method to display the names in the string grid. (21) Copyright reserved Please turn over

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.

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.
