QUESTIONS

SECTION A 
QUESTION 1: GENERAL PROGRAMMING SKILLS 

All Grade Twelve learners have to check their examination entry for the National  Exam at the end of each year. Subject changes are allowed, but all supporting  documents must be submitted. All information that is entered, must be correct.  


INSTRUCTIONS: 

  • The project Question1 is provided in the TrialExam2016 folder. 
  • Open the incomplete project file called Question1_p.  


1.1 Question 1.1 Button 
The learner must enter his/her name and surname in the given text area. The  relevant grade must be selected. The old and new subject must also be  selected. If the old and new subject is the same, display an ‘Incorrect  Information’ message. If no subject change is made, display the learner’s  details and ‘No subject change’. If a subject change has been made, display  the learner’s information as well as a message indicating that all required  documents should be submitted. 
Example of output: 

INCORRECT INFORMATION:                                                                                    NO SUBJECT CHANGE: 
INCORRECT INFO 1                    NO SUBJECT CHANGE

SUBJECT CHANGE   (13)

Question 1.2 Button 
The ID number must be validated by comparing it with the date of birth.  Display a suitable message to indicate whether it is correct or incorrect. 
Example of output: (8)
EXAMPLE OF OUTPUT 1.2
1.3 Question 1.3 Button 
A username needs to be created. It is generated by removing all the vowels  and spaces from the candidate’s name and surname (as entered in  Question 1.1); ‘%’; a random number between 100 and 300 (inclusive) and ‘#’. 
Example of output (Take note: The output will be different due to random  numbers): (11)
1.3 P1 IT
1.4 Question 1.4 Button 
Code must be written to calculate whether the candidate has achieved a pass  based on the marks they have entered.  
Requirements for a pass are as follows: 

  • Home Language must be 40% or more 
  • 40% in three other subjects 
  • 30% in two subjects
    Display on the panel whether the candidate has passed or failed.

Example of output:

  • 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 SECTION A: 47

SECTION B 
QUESTION 2: OBJECT-ORIENTED PROGRAMMING 

To get admission to tertiary institutions one must achieve a certain amount of  Admission Points depending on the course and institution.  


INSTRUCTIONS: 

  • The project Question2 is provided in the TrialExam2016 folder, which contains:
    • A main form unit called Question2_u.pas 
    • An incomplete unit file called clsLearners.pas
  • Open the incomplete project file called Question2_p and the class called  clsLearners.pas 


2.1

2.1.1 Declare an array with class scope which will store the candidate’s  marks (maximum 10 subjects). The private attributes are given; declare  the public methods as you answer the questions below. (7) 
2.1.2 Write code for the constructor method which will receive and assign the  candidate’s name and number of subjects. The attribute fapspoints must be initialised. (3) 
2.1.3 Write a method called APS which will receive the marks from the array,  convert it to the respective level and then calculate the APS points. APS points are calculated by converting the percentages to the  respective levels and adding the levels together. 

Percentage           Level 
80-100                     7 
70-79                       6 
60-69                       5 
50-59                       4 
40-49                       3 
30-39                       2 
0-29                         1 (4) 

2.1.4 Write a method called BachPass which will receive the marks and  return whether the learner has achieved a bachelor’s pass.  
In order to qualify for a bachelor pass, the learner must achieve at least  50% in four subjects. Assume that all the subjects are from the  designated list of subjects. (8) 
2.1.5 Write a method called CompileString which will return the information  as shown in the following format: 

Learner’s Name: <fname> 
Bachelor Pass: <Yes/No> 
APS Points: <fapspoints> (3)

2.2 The learner’s name must be entered in the text area; then the number of  subjects that the learner is enrolled for must be entered using an InputBox  component.  
If the learner entered less than 7 subjects, then the learner must enter the  number of subjects again until it is 7 subjects or more. 
The learner must enter the marks and these marks must be stored in an array.  Once the marks are entered, then the program must check whether the learner  qualifies for a bachelor pass. If the learner has a bachelor pass, then APS must  be calculated. All the information must be displayed as shown in the example  below. All relevant methods must be called. 
If the learner does not qualify for a bachelor pass, a suitable message must be  displayed. (17) 
Example of output: 
EXAMPLE OF OUTPUT 2.2 SECTION B IT

  • 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.

SECTION C 
QUESTION 3: PROBLEM SOLVING PROGRAMMING 

A record of all the exam numbers and centres must be kept accurately for statistical  purposes. Sometimes new candidates are added and some are deregistered for  various reasons. It is also important to know how many candidates each centre has.  


INSTRUCTIONS: 

  • The project Question3 is provided in the TrialExam2016 folder.
  • Open the incomplete project file called Question3_p.  


You are required to design a program that must be able to do the following: 

  • Get the exam numbers from a text file named examnumbers.txt
  • Sort and display the exam numbers
  • Search for a specific centre 
  • Add a new exam number to the array and text file 
  • Delete an exam number 

Read the following sections before attempting the solution: 

  • GUI and data supplied 
  • Program requirements 
  • Mark allocation 

NOTE: 

  • You may NOT modify data supplied. 
  •  The use of good programming techniques and modular design must be applied in  the design and coding of your solution.

GUI AND DATA SUPPLIED 
GUI 
The GUI contains components for input and output. Additional components will be  required. At least one dynamic component must be used.  
Example of GUI provided: 
GUI
DATA 
The exam centre number forms part of the candidate’s exam number. If the candidate’s exam number is 4151610060031, then it can be interpreted as  follows: 

  • The last four numbers (0031) represents the candidate’s number at the centre
  • The centre number consists of the numbers following the positions: 1; 4 – 9  (4161006)
  • The second and third number (15) can be ignored in this question.

The exam centres are stored in a one-dimensional array called arrcentres.
The examnumbers of the candidates are stored in a textfile named  examnumbers.txt. 

PROGRAM REQUIREMENTS 
Get Information, Sort and Display 

  • Get the contents of the examnumbers.txt text file. 
  • Sort it in ascending order. 
  • Display the sorted exam numbers. 

Search for centre number 

  • The user must enter a centre number. 
  • If the centre number is found, the school name as well as all the exam numbers  from that particular centre must be displayed.
  • The total number of candidates must be displayed as well.
  • If the centre number is not found, a suitable message must be displayed.

Add exam centre and exam number 

  • Get the information that must be added from the user
  • Add the exam number to the array as well as to the text file 
  • Display a message that the exam number has been added to the text file ∙ Sort and display the updated array 

Delete an exam number 
Sometimes candidates are deregistered due to various reasons. 

  • Ask the user to enter the exam number to be removed 
  • Delete the exam number from the text file as well as from the array 
  • Display a message once the exam number is deleted 
  • Sort and display the updated array 
  • Write the updated array to the existing text file
