Time Allowed: THREE hours
Answer QUESTION 1 from Section A AND any THREE questions from Section B.
Question 1 carries 34 marks. All other questions carry 22 marks. You should spend no longer than 1 hour on question 1. Unless specified otherwise, you may use a programming language(s) of your choice.
SECTION A
Q1.
A ticket station sells tickets for ‘bus’, ‘train’, or ‘boat’ trips around a large zoo. Trip prices vary depending on the age of the customer (as children receive a 50% reduction on the standard adult price), and also depend upon the chosen travel method (bus, train, or boat). The station management requires a software program to track the number and type of tickets (that is, bus, train, or boat) sold at the end of each working day, as well as the associated monies taken in at the ticket station on a daily basis. In addition, for each transaction the system produces an onscreen summary of ticket(s) bought, showing the total overall price of the ticket(s), the number of ticket(s) bought (for example, a person bringing their family on a trip may buy 2 adult and 3 child tickets in a single transaction), and the total price for that transaction. The software program will be installed on the solitary ticket seller’s computerised till at the ticket station.
Sketch a suitable user interface for this software, indicating and naming all the controls.
Write the source code necessary for the functioning of your user interface design.
(34 marks)
Q3.
Describe in detail each of the following terms, and separately in each case give examples of how they are used with respect to VB.NET:
(a) Variables (b) Object Oriented programming (c) Database connectivity
(22 marks)
Q4.
(a) Give a full explanation of what each of the following separate pieces of code is doing. Include a complete description of all line(s) of each piece of code.
(i) Me.Close()
(ii) With Me .carTypesComboBox.Add.Item(.Text) End With
(iii) costDecimal = Decimal.Parse(Me.amountTextBox.Text)
(iv) #define HANDLING_CHARGE 1
(8 marks)
(b) The code below contains 4 separate errors, and is not commented. Rewrite a fully commented and error-free version of this code in your answer book_. (Your code comments should fully inform a reader of what is happening in the code)._ The code is related to the application screenshot below.
Private Sub SaveFlavourListToolStripMenuItem_Click(ByVal sender As _ System.Object, ByVal e As System.EventArgs) Handles _ SaveFlavourListToolStripMenuItem
Dim numberOfItemsInteger As Integer Dim flavoursStreamWriter As New StreamWriter("Coffees.txt")
numberOfItemsInteger = Me.coffeeComboBox.Count - 1
For indexInteger As Integer = 0 To numberOfItemsInteger flavoursStreamWriter.WriteLine(Me.coffeeComboBox.Items(indexInteger)) Loop
flavoursStreamWriter.Close mIsDirtyBoolean = False End Sub
(14 marks)
Q5.
(a) Using a programming language of your choice write a FUNCTION that takes 2 integer arguments (say p and q ), and returns 1 if p is an exact numerical multiple of q , otherwise returns 0. For example, if the function’s arguments were (30, 5) then the function would return 1 because 30 is a multiple of 5.
(8 marks)
(b) A program asks a user to input a whole number (n) between 1 and 100. Write a FOR loop that sums the cumulative added total of the positive whole numbers up to and excluding n. (For example, if the user enters '5', the FOR loop will calculate and return the value of 1+2+3+4 only).
(14 marks)
Q6.
(a) Create a C application that asks the user to input a salary amount in euro and cent (for example 323.56, rather than €323.56), and calculates and displays the tax due, and the net amount remaining after tax is deducted. Tax is calculated at the following rates: No tax is due on the first €100; 22% is due on the next €250, and 42% is due on subsequent amounts.
The output may resemble:
Enter salary please: 640.
Total Tax due: 177. Remaining Amount: 463.
(10 marks)
(b) Using a programming language of your choice create an application that asks a user to enter an integer between 0 and 1000, and displays the smallest of that number’s separate digits. For example, if the user enters 72 the program displays 2; or if the user enters 836 the program displays 3. (12 marks)
29 printf("Gross pay: %7.2f\n", gross); 30 /* Don't need return value */
31 } /* end of function */ 32 33 void info(void) /*************************** Decode employee info */
34 { 35 int emp_id, emp_num, dept;
36 37 printf("Enter Employee ID: ");
38 scanf(%d, &emp_id); 39 emp_num = emp_id / 10; /* Separate emp num by deleting 40 last digit */
41 printf("Employee #%d in the ", emp_num); 42 dept = emp_id % 10; /* Dept number is last digit of emp_id */
43 switch (dept) 44 {
45 case 1: 46 printf("Accounting");
47 break; 48 case 2:
49 printf("Manufacturing"); 50 break; 51 default:
52 printf("Sales or other"); 53 }
54 printf(" department.\n"); 55 }; /* End of function */
