          • A check box that indicates whether speed post must be used. A standard
            amount of R100,00 is charged for speed post.

          When the user clicks on the Delivery cost button the number of kilometres
          entered in QUESTION 1.1, the selected weight category and whether speed
          post is required or not must be used to calculate the delivery cost.

          Example of the output if the number of kilometres is 635, the weight of the
          item to be delivered is in the A2 category and speed post is required:

                                                                                               (10)

1.3       Button – [Delivery box number]

          Example of output when speed delivery is NOT required in QUESTION 1.2:

          NOTE:      Due to the nature of the random function the value for the delivery
                     box displayed in the screenshot above may differ from the value
                     displayed by your program.                                               (9)

1.4       Button – [Validate bar code]

                                           NSC

          The bar code number consists of twelve digits. For example, the bar code
          number shown in the picture above is 639382000393. The last digit of a UPC
          is called a check digit. The check digit is used by a scanner to determine
          whether a bar code is valid or not.

          Use the algorithm below to write code for the Validate bar code button. The
          code needs to verify the check digit and display a message to indicate
          whether the bar code is valid or not.

          Algorithm:

          1.     barCode  text box value
          2.     sumOddPositions  0
          3.     sumEvenPositions  0
          4.     loop from first digit to second last digit of barCode
          5.       if the logical position of the digit in the bar code is even
                          sumEvenPositions sumEvenPositions + digit at position
                   else
                          sumOddPositions sumOddPositions + digit at position
          6.     sum  sumOddPositions * 3 + sumEvenPositions
          7.     checkDigit  10 – (sum modulus 10)
          8.     if checkDigit = last digit of barCode
                          display the check digit and a suitable message indicating that
                          the bar code is valid
                 else
                          display a suitable message indicating that the bar code is invalid

          Example:

          If the bar code is 639382000393 then:

                 sumOddPositions = 6+9+8+0+0+9 = 32
                 sumEvenPositions = 3+3+2+0+3 = 11

1.5       Button – [View and save deliveries]

          All deliveries for December 2014 are stored in the given array called
          arrDecDeliveries. The format of each entry in the array is as follows:

          <date><space><place of departure><space>to<space><destination>

          Example:

          2014-12-01 Durban to Cape Town

          The user has to select a city from the provided combo box. All the deliveries
          that were made during December 2014 to or from the selected city must be
          displayed in the provided output area and also written to a text file.

          Write code to do the following:

          • Create a text file where the name of the file is made up of the text
            'December2014' combined with the name of the city that was selected.

             Example:

             If Durban was selected, the            name    of    the   text     file   must
             be December2014Durban.txt.

          • Use the data stored in the arrDecDeliveries array and display the
            deliveries to and from the selected city in the output area provided. Use the
            name of the city as a heading.

          • Store the deliveries to and from the selected city in the text file that was
            created – one delivery per line.

          Complete the code in the given delivery class (TDelivery/Delivery) as
          described in QUESTION 2.1.1 to QUESTION 2.1.4 below:

          2.1.1      Write code for a constructor method to receive the delivery
                     number, truck number, odometer reading at the start of the delivery
                     and odometer reading on completion of the delivery as parameter
                     values. Assign these values to the relevant attributes of the object
                     class.                                                                     (3)

          2.1.2      Write a mutator method and an accessor method for the
                     fFuelUsed/fuelUsed attribute.                                              (4)

          2.1.3      Write a method called calculateDistance to calculate and return
                     the distance travelled based on the start and end odometer
                     readings for the delivery.                                                 (3)

          2.1.4      Different toll fees must be paid on different toll routes. The routes
                     used are RN1, RN2, RN3 and RN4. Toll fees on these routes are
                     dependent on the type of truck used. The company's trucks are
                     classified as follows:

                     •      Light-duty trucks: Tr1, Tr2
                     •      Medium-duty truck: Tr3
                     •      Heavy-duty trucks: Tr4, Tr5

                     A two-dimensional array called tollFees contains the toll fees for
                     the different routes for different types of trucks and is supplied as
                     part of the given code. The contents of the array can be
                     represented as follows:

                                   Light-duty      Medium-duty    Heavy-duty
                                      truck           truck         truck
                         RN1            R105,50         R135,00       R210,00
                         RN2             R35,00          R54,00        R82,00
                         RN3             R85,00         R129,00       R205,00
                         RN4            R112,00         R170,00       R219,00

                      Rows:           Represents the routes RN1 to RN4
                      Columns:        Represents the types of trucks

                     Write a method called determineTollFees to determine and return
                     the toll fees to be paid for the delivery. The method must receive
                     the route (RN1, RN2, RN3 or RN4) as a parameter. Use the
                     two-dimensional array called tollFees to look up the toll fee for the
                     route and type of truck that was used for the delivery.

                      NOTE: It is compulsory to use the given two-dimensional array in
                            your solution to look up the toll fee.                              (10)

2.2       A text file named DeliveryInfo.txt contains an unknown number of lines of
          information on previously completed deliveries. Each line of information
          contains data on a single delivery in the following format:

          <delivery number>#<truck number>#<odometer reading on completion
          of the delivery>

          Example of some of the data in the text file named DeliveryInfo.txt:

          1#Tr1#121110
          2#Tr2#8010
          3#Tr3#15021
          4#Tr4#700
          5#Tr1#121453
          6#Tr3#15653
          :

          The data of the first delivery can be interpreted as follows:

          •   Delivery 1 identifies the delivery.
          •   Truck Tr1 was used to make the delivery.
          •   The reading on the odometer on completion of the delivery was 121110.

          Do the following to complete the code for each button in the main form unit
          (Delphi)/GUI class (Java) as described below:

          2.2.1       Button – [Get data from file]

                      •     Select the specific truck to be used from the provided Truck
                            number combo box.

                      •     Use the given text file DeliveryInfo.txt to determine the
                            following:

                            o   New delivery number
                                The delivery number for the new delivery will follow on the
                                number of the last delivery stored in the text file. If the
                                information of 20 deliveries are stored in the text file, the
                                number of the new delivery will be 21.

                            o   Start odometer reading
                                The odometer reading for the last delivery that was made
                                by the selected truck must be used as the start odometer
                                reading for the new delivery.

                                Example:

                                If truck Tr4 is selected and the odometer reading that was
                                captured in the text file on completion of the last delivery
                                for Tr4 is 1648, then the value of 1648 must be used as
                                the odometer reading at the start of the new delivery.

          2.2.4       Button – [Check fuel used]

                      The driver of the truck is required to refill the fuel tank at the end of
                      each delivery. Due to the nature of the routes, the amount of fuel
                      used to refill the tank may sometimes differ from the fuel calculated
                      for the delivery.

                      Write code to do the following:

                      •     Enter the amount of fuel used to refill the tank in the text box
                            provided.

                            HINT: The value of 75 can be used to test the code.

                      •     Obtain the calculated amount of fuel used from the relevant
                            attribute in the object class.

                      •     Calculate the difference between the fuel used to refill the tank
                            and the calculated fuel used as stored in the attribute of the
                            Delivery object.

                            o     If    the    difference   is   less    than    10%,    the
                                  fFuelUsed/fuelUsed attribute must be updated by setting
                                  its value to the new value as entered in the text box.

                                  An appropriate message must be displayed in the text
                                  box provided, indicating whether the value of the
                                  fFuelUsed/fuelUsed attribute has been updated or not.

                                  Example of the output if the delivery was done by truck
                                  Tr4 and the actual fuel used is 75,0:

                            o     If the difference is greater than or equal to 10%, an error
                                  message should be displayed and the value of the
                                  fFuelUsed/fuelUsed attribute must not be updated.

SECTION C

QUESTION 3: PROBLEM-SOLVING

SuperTrans Courier Services provides a daily speed service from Cape Town to
Johannesburg. The storage space in the truck used for the deliveries is divided into
two shelves for fragile and non-fragile items respectively. The maximum capacity of the
shelf reserved for fragile items is 20 items while a maximum of 30 items can be placed
on the shelf reserved for non-fragile items. The loading zone at the company controls
the clearing of a load, loading of items into the truck and checking the status of the
truck load at any given time.

An incomplete program has been provided to manage the loading of trucks.

      The output area of the GUI labelled 'Loading progress display area' represents the
      storage area of the truck. An asterisk (*) is used to represent an item placed on a
      shelf.

      Example of the display of a fully loaded truck with 20 fragile and 30 non-fragile
      items:

•     Write code to complete QUESTION 3.1 to QUESTION 3.3 as explained in the
      instructions below:

3.1        Button – [Load item]

           Write code to do the following when an item is loaded:

           •   Create a loading code.
           •   Add the item, represented by an asterisk (*), to the correct shelf in the
               loading progress display area.

           Loading code:

           The loading code is compiled using the letter 'F' for fragile items and the
           letters 'NF' for non-fragile items, followed by the sequence number of the item
           on the shelf.

           For example:

           F1 refers to item 1 on the shelf for fragile items.
           NF6 refers to item 6 on the shelf for non-fragile items.

           Add item to loading progress display area:

           If there is space on the shelf, create and display the loading code in the text
           box provided and update the loading progress display area to show the new
           item.

           If the item cannot be loaded, the loading code must be left empty and a
           dialog box must be used to display the following message: 'Loading of item
           cannot be processed – No loading space'

           Example of output of the 'Loading progress display area' if the item loaded is
           the first non-fragile item. In this example five fragile items have already been
           loaded (on the next page):

        Example of an attempt to load a fragile item when the shelf for fragile items is
        full:

                                                                                               (20)

3.2       NOTE:        If you could not complete QUESTION 3.1, use the data below to
                       complete QUESTION 3.2:

                       Number of fragile items:          4
                       Number of non-fragile items:      13

          Button – [Check load status]

          The delivery can be made if the truck has a minimum load of:

          •    50% fragile items (10 fragile items), and
          •    50% non-fragile items (15 non-fragile items)

          When this button is clicked, a load status report must display a summary of
          the number of both fragile and non-fragile items, using the following column
          headings:

                     Item type         Number of items          Percentage loaded

          • If the percentage of items loaded is 50% or more for both fragile and
            non-fragile items, the message 'The delivery may progress' must be
            displayed.

            • If the percentage of items loaded is less than 50% for fragile OR
              non-fragile items, then the message 'The delivery may not progress'
              must be displayed along with the outstanding number of items for each
              type required to make up the minimum load.

           NOTE:     Marks will be awarded for column formatting and for displaying the
                     percentage loaded to TWO decimal places.

           Example 1:       If the load status of the truck is 4 fragile items and 10 non-fragile
                            items, the load status report should be as follows:

           Example 2: If the load status of the truck is 12 fragile items and 17 non-fragile
                      items, the load status report should be as follows:

                                                                                                    (17)
