Programming As part of its advertisement campaign, “Cinema for all” is giving special season’s discounts on the prices of tickets for groups. The original price per ticket for an adult is L.L. 8000 and for a child is L.L. 5000. The special season’s offer is summarized in the following table: Special Season’s Discounts Child Price per ticket= L.L.4000 Number of tickets Discount rate ≥ 40 35 % Adult ≥ 70 50 % We would like to build a VB.Net application that calculates the cinema fee for a group of people during the discount season. The program takes as input, the number of child tickets, as well as the number of adult tickets. Before processing the input to calculate the fee, the program validates input in the following manner: • For child tickets: The program assumes that the user correctly enters a number into the textbox. The program should reset any negative input to zero. • For adult tickets: In case the input for adult tickets is not a number, the program should repeatedly ask the user to reenter the number of adult tickets up to two times using an inputbox. In case after the second trial the input for adult tickets is still not a number, the program should then display a message box saying: “Error: Exceeded number of trials” and discontinue the event procedure. The graphical user interface for the “Cinema for All” project is shown below along with the skeleton of the click event procedure for btnCompute. Sample Output1: Assume the user wanted to buy 10 child tickets and 100 adult tickets, the program will display: Sample Output2: Assume the user wanted to buy 10 child tickets and 0 adult tickets, the program will display: Department of Computer Science Fall 2006 CMPS 209 – Final Exam-Sample Questions 90 minutes 3/8 Your handwriting should be readable so that it can be graded.
