The number of counters that will be opened and manned by their staff will depend on the number of customers in the queue. If a flight is delayed, the passengers on the delayed flight will be requested to queue at a separate counter. Do the following: DELPHI PROGRAMMERS JAVA PROGRAMMERS • Open the incomplete project file called • Open the incomplete class called Question3_P.dpr in the Question3 Question3.java in the folder Source folder. Packages (src), Question3Package in the Question3 folder. • Enter your examination number as a • Enter your examination number as a comment in the first line of the main comment in the first line of the class form unit called Question3_U.pas. called Question3.java. Read the following sections before attempting the solution: • GUI and data supplied • Program requirements • Mark allocation NOTE: • You may NOT modify data supplied manually. Code must be added to manipulate the data supplied according to the requirements. • The use of good programming techniques and modular design must be applied in the design and coding of your solution. Copyright reserved Please turn over ### Page 18 Downloaded from hlayiso.com Information Technology/P1 18 DBE/2017 NSC Supplied graphical user interface (GUI): The supplied GUI contains components for events that need to take place. Use the program requirements in the questions that follow to decide on a suitable output component to be placed in the output area labelled Airline counters in the GUI. Supplied data: A one-dimensional array called arrPassengers has been declared and will contain the information of passengers who must collect their boarding passes at the check-in counters at the airport. Supplied code will populate the arrPassengers array with an unknown number of elements obtained from the arrPosPassengers array when the program is executed. The number of elements allocated to the arrPassengers array will be in the range from 1 to 35 and will be determined randomly. You must use the arrPassengers array in your code. The format of the data in the arrPassengers array is as follows: (B – business class or E – economy class), the position of the passenger in the queue (starting at 01) and the flight number, as shown below: ; Example of passenger information in the arrPassengers array: E01;TDB2506 B02;TDB2506 E01;TDB1305 Copyright reserved Please turn over ### Page 19 Downloaded from hlayiso.com Information Technology/P1 19 DBE/2017 NSC A two-dimensional array called arrGrid with nine rows and four columns has been declared. In your solution this array will not necessarily contain 36 elements, as the number of passengers contained in the arrPassengers array will determine the number of elements contained in the arrGrid array. Program requirements: 3.1 Button [3.1 – Queues at check-in counters] The program must place the passengers waiting for their boarding passes (contained in the arrPassengers array) in queues at the check-in counters. The number of passengers contained in the arrPassenger array determines the number of open check-in counters by using the following criteria: NUMBER OF OPEN NUMBER OF PASSENGERS TO CHECK-IN COUNTERS RECEIVE BOARDING PASSES 1 Less than 10 2 10 to 16 3 17 to 24 4 More than 24 Do the following: • Use the arrGrid two-dimensional array to represent the open check-in counters and passengers allocated to these counters. Passengers must be allocated to counters as follows: o Business class passengers must be placed first in the queues at the check-in counters, followed by economy class passengers. o The passengers must be distributed as evenly as possible amongst the queues at the check-in counters, as shown in the examples of output that follow. • Display suitable headings for the check-in counters. • Display the class and number of the passengers. Example of output if 16 passengers are waiting to receive boarding passes: Copyright reserved Please turn over ### Page 20 Downloaded from hlayiso.com Information Technology/P1 20 DBE/2017 NSC Example of output if 33 passengers are waiting to receive boarding passes: NOTE: The output is determined by the number of elements that the arrPassengers array contains. 3.2 Button [3.2 – Passengers on delayed flight] When a flight is delayed the passengers booked on the delayed flight must be removed from the queues at the open check-in counters and placed in a queue at a separate counter. A combo box with flight numbers is provided to select the flight number of a delayed flight. The user must select the delayed flight and click on the QUESTION 3.2 button. The program must do the following: • Remove the information of all passengers booked on the delayed flight from the queues at the check-in counters and display their details in the output area provided. • Update the display of the queues at the check-in counters. The passengers at the check-in counters must still be distributed evenly amongst the counters; first the business class passengers and then the economic class passengers. Example of output if flight TDB2506 was selected from the combo box as a delayed flight and the arrPassengers array contains 33 elements: Copyright reserved Please turn over ### Page 21 Downloaded from hlayiso.com Information Technology/P1 21 DBE/2017 NSC Mark allocation: MAXIMUM REQUIREMENTS MARKS QUESTION 3.1 Determine number of open counters and number of passengers per row 6 Allocate position according to passenger class 5 Copy information from given array to correct data structure 8 Display passengers in queues at correct number of counters 7 QUESTION 3.2 Determine and display passengers on the delayed flight 6 Remove passengers on delayed flight from queues 6 Update information in data structures and output 2 • Enter your examination number as a comment in the first line of the program file. • Save your program. • Make a printout of the code if required.
