Booking for seats is usually done in advance using credit cards. QUESTION 1: DELPHI PROGRAMMING You have been asked to come up with a Boolean credit validation function using the Luhn algorithm to ensure that the credit card number is correct. The number of digits must be between 13 and 19. The Luhn formula:  Drop the last digit from the number. The last digit is what we want to check against  Reverse the numbers  Multiply the digits in odd positions (1, 3, 5, etc.) by 2 and subtract 9 from all the results greater than 9  Add all the numbers together  Mod by 10  The number will be correct if your answer is the same as the last digit which was removed in the first step Luhn example: Step Total Original 4 5 5 6 7 3 7 5 8 6 8 9 9 8 5 5 number: Drop the last 4 5 5 6 7 3 7 5 8 6 8 9 9 8 5 digit: Reverse the 5 8 9 9 8 6 8 5 7 3 7 6 5 5 4 digits: Multiple odd 10 8 18 9 16 6 16 5 14 3 14 6 10 5 8 digits by 2: Subtract 9 to numbers 1 8 9 9 7 6 7 5 5 3 5 6 1 5 8 over 9: Add all 1 8 9 9 7 6 7 5 5 3 5 6 1 5 8 85 numbers: Mod 10: 85 modulo 10 = 5 (last digit of card) Copyright reserved Please turn over ### Page 4 Downloaded from hlayiso.com 4 INFORMATION TECHNOLOGY P1 (SEPTEMBER 2014) Open Question1_dpr and complete the questions: 1.1 Question 1.1 Tab: FUNCTION: 1.1.1 Declare a Boolean function named CCValidate which receives a credit card number as a string variable and returns whether the credit card number is valid or invalid. (2) 1.1.2 Remove any letters from the credit card number. (5) 1.1.3 Check the length of the remaining number. The function must change to false if this criteria is not met. (3) 1.1.4  Save last digit in a variable and remove it from remaining number  Start a loop to reverse the number  Multiply the numbers in odd position by 2; if the number is greater than 9 subtract 9 from that number  Add the numbers together  Mod the number by 10  Compare number with saved last digit  The function becomes false if this criteria is not met. (11) 1.1.5 Validate Button: Test the function by entering a credit card number. Display a suitable message whether the credit card number is valid or not. (4) Test your program against these numbers: 4844044457514178, 30488409449900, 5415229692213231, hiuw1234768 Copyright reserved Please turn over ### Page 5 Downloaded from hlayiso.com (SEPTEMBER 2014) INFORMATION TECHNOLOGY P1 5 1.2 Question 1.2 Tab: When seats are booked, random ticket numbers are generated. 1.2.1 Declare two arrays with class scope, one to store the ten randomly generated numbers and the other to store the numbers without duplicates.

You are required to produce a solution that includes all classes specified in the instructions. No marks will be allocated to any alternative solution such as one program not creating an object. The database, augp3.mdb, supplied in the Q2 Folder contains results of the Formula 1 race in Australia in 2013. The database contains one table named tblAUGP. The tblAUGP table stores data on the registered drivers for 2013. The fields in this table are defined as follows: Field Name Type Description DRID Text Primary key for the table: Driver ID Name Text Name and Surname of Driver Country Text Nationality of Driver Team Text Team of Driver Time Text Time taken to complete the race The following table is an example of the data contained in the table named tblAUGP: Load Q2_australia.dpr and you should be presented with the following multiform project.

If the connection to the database is giving you problems ensure that the data aware components on the AUDatam form, have the following properties:  The ADOConnaugp3.ConnectionString property: Click on the two dots and select the Microsoft Jet 4.0 OLE DB Provider driver. Under the file name put AUGP3.mdb. Remove the user name and select blank password.  The ADOConnaugp3.LoginPrompt property should be false.  The ADOTaugp3.Connection property should be ADOConnugp3.  The ADOTaugp3.Tablename property should be tblAUDB.  The DataSaugp3.Dataset property should be ADOTaugp3. 2.1 Open the unit called clsDriver. 2.1.1 Define a class with the name TDriver. (1) 2.1.2 The class must contain the following private fields with appropriate data types: fName: to hold the name and surname of driver fCountry: to hold the name of the driver’s country fTeam: to hold the name of the driver’s team fTime: to hold the time taken by the driver in the format: h:min’sec (4) 2.1.3 Create a constructor named Create that will receive four parameters and initialise all the fields. (7) 2.1.4 Create a method getfName that will return the name (not surname) of the driver. (3) Copyright reserved Please turn over ### Page 8 Downloaded from hlayiso.com 8 INFORMATION TECHNOLOGY P1 (SEPTEMBER 2014) 2.1.5 Create a method getAverage that will return the average speed of each driver in the format as shown in the example. Example: The average speed is calculated by multiplying 58 laps and 5 900 m then divide by the time taken in seconds. Time in seconds = (hoursx60X60+minutesx60+seconds) (5) 2.1.6 Create a method toString that will return the name, country, team and time (h:min:sec) as one string.
