SECTION B 
QUESTION 2: OBJECT-ORIENTATED PROGRAMMING 
The local supermarket has a loyalty card system where customers can receive rewards  depending on the number of visits, the number of loyalty points gathered and the  percentage of health food bought. 
Do the following: 

• Compile and execute the program. Currently the program has no functionality. Example of graphical user interface (GUI): 

• Complete the code for this program, as specified in QUESTION 2.1 and  QUESTION 2.2 below. 

2.1 The given incomplete object class (TCardHolder/CardHolder) contains the  declaration of five attributes, the toString() method and an incomplete  isCorrect() method.
The given attributes of the CardHolder object: 

Complete the code in the given CardHolder class (TCardHolder/CardHolder)  as described in QUESTION 2.1.1 to QUESTION 2.1.6 below. 
2.1.1 Write code for a constructor method to receive the card number,  cellphone number and loyalty card points already received, as  parameter values. Assign these values to the relevant attributes. The lowest code for the health food level (S) must be assigned to the  attribute for the health level. The attribute for the number of visits must  be set to 0. (5) 
2.1.2 Write a mutator method to be able to set the attribute for the number of  visits to a value received as a parameter. (2) 
2.1.3 Write code for a method called increaseLoyaltyPoints that receives  the total amount spent for this month as a parameter and increases the  current number of loyalty points based on the amount received. 
Use the following criteria:  

• For every four rand (R4) spent, one loyalty point is awarded. (5) 

2.1.4 Write code for a method called updateHealthLevel that will receive the  total amount spent for this month and the amount spent on health food for this month as parameters. Calculate the percentage that was spent  on health food and set the attribute for the health level according to the  criteria provided in the table below. 

(7)

2.1.5 An access code is required to be able to update a customer's loyalty points. The customer's cellphone number has been used to compile the  access code. 
Write code to complete the isCorrect method provided. The method  must test whether the access code received as a parameter is correct  by applying the following instructions on the attribute for the cellphone  number: 

• Remove all zeros (0) from the cellphone number. 
• Determine the sum of the remaining digits as follows:
  • If the number of remaining digits is even, every two consecutive  digits starting on the left-hand side must be regarded as a two digit value. Add all these two-digit values.
    Example:
    If the original cellphone number was 082 340 2113, the  remaining digits without any zeros would be 82342113. The sum  of the two-digit values is:
    82 + 34 + 21 + 13 = 150
  • If the number of remaining digits is odd, the first digit must be regarded as a one-digit value, and thereafter every two  consecutive digits must be regarded as a two-digit value. Add all  these values.
    Example: 
    If the original cellphone number was 082 034 2101, the  remaining digits after removing the zeros are 8234211. The sum  of the values is:
    8 + 23 + 42 + 11 = 84 (13) 

2.1.6 Write code for a method called identifyStarShopper that will return a  string to indicate whether the card holder is a STAR shopper or not. A card holder is a STAR shopper if the following applies: 

• The card holder earned more than 2 000 loyalty points and the  shop was visited more than 10 times during the month.
  OR 
• The health level of the card holder is platinum. 

The string to be returned must either be 'STAR shopper' or an  empty string. (6)
2.2 Information on the visits and purchases of card holders is saved for one month  only in a text file. The text file called DataJanuary2017.txt contains the  transactions made by four of the card holders during January. 
The contents of text file is as follows: 

• Every three lines represent a transaction for a specific loyalty card holder:
  • Line 1: The card number of the card holder, for example B921-3$-DI
  • Line 2: The total amount of the purchases for this visit, for example 1459.30
  • Line 3: The amount spent on health food during this visit, for example 72.30 

Example of the first 12 lines of the text file DataJanuary2017.txt: 

B921-3$-DI 
1459.30 
72.30 
B870-4%-CH

NOTE: A perfect number is when the number is equal to the sum of the factors of the number, excluding the number itself. 
Example:

The number 6 was randomly generated.  
The sum of the factors of 6, excluding 6, is: 1 + 2 + 3 = 6 
The number 6 is therefore a perfect number. 

The following pseudocode was given to solve the problem: 

5.4.1 Use the following headings and complete the trace table with the  number 4 as the randomly generated number. Show EACH step of  your trace. 

 (5)
