FIRST YEAR BSc. IN BUSINESS INFORMATION SYSTEMS EXAMINATION (MS111) BUSINESS APPLICATION DEVELOPMENT 1 Dr. Danail Ivanov Dr. Michael Lang Dr. Tom Acton Time Allowed: TWO hours Answer QUESTION 1 and one other question. All questions carry equal 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.
Q1 (compulsory). The screenshot below shows a retail ice cream sales application at runtime. Write the Visual Basic (or C#) code for the entire application using the code skeleton provided below. Ensure that all necessary controls and/or variables are named according to best practice.
Q 4.
(a) Write pseudocode for the following scenario (do NOT write actual code): Each of four salespersons is paid his/her salary every calendar month. Each monthly base salary amounts to €1600. The gross (that is, total amount of) pay for this time period is based on a base salary plus commission. In each case a commission of 10% of base salary is added where the sales amount for that salesperson exceeds €50, in that month. Income tax is calculated as 20% of total earnings, and is deducted from gross pay to yield net pay. A personal statement of earnings for that month is issued to each salesperson, showing salary, commission, gross pay, net pay, and tax deducted. ( 10 marks) (b) The application below allows the user to type a monetary amount into a text box. Depending on the transaction type, upon the user clicking the ‘Calculate’ button, the application either adds the amount to the existing account balance or reduces the balance accordingly. Write a sub procedure to manage the behaviour of the ‘Calculate’ button. ( 15 marks) (c) Create an application that asks a user to enter a temperature in degrees Celsius (C), and converts and displays the equivalent in degrees Fahrenheit (F). Use the formula F = (C * 9 / 5) + 32 (15 marks) (d) An application produces mailing labels for a postal service. The screenshot overleaf shows part of the application at runtime. The related code that follows has five errors, each on separate line numbers (and excluding lines with code comments). Specify the line numbers where the errors occur, and in each case provide a corrected line of code.
