Attributes • NightNo To represent flight number. • destination to represent the destination city. There is a list of 7 destinations to choose from which are: Dammam, Jeddah, Yanbu, Hail, Abha, Tabuk and Taif. gate To represent the gate number for a flight. date To represent the flight date in the format (dd/mm). departure Time To represent the departure time in the format (hh:mm) where 24-hours system is applied. arrival Time To represent the arrival time in the format (hh:mm) where 24-hours system is applied. Constructors • Flight A default constructor that initializes all attributes, integers are initialized to zero and strings are initialized to null Flight(string dest, int g, string d, string depTime) Another constructor that initializes a flight with initial values for all the attributes by calling the function setAllInfo. Functions setAllInfo() It set all the flight attributes as follows: (1) set destination, gate, date and departure Time from the received parameters: (i) set arrival Time by calling the function calculate Arrival Time(): and set flightNo by calling the function generate FlightNo. generate FlightNo0lt generates and stores a flight number in flightNo. The flight No is formed as follows: the first three characters in the destination (in uppercase) followed by "00" and concatenated with the totalFlights number Example: If the destination is Dammam and the current totalFlights is 3 → flightNo is DAM003 • calculate ArrivalTime) It calculates arrivalTime based on the destination and the duration of the flight. It then checks whether the arrival time will be in the next day or not. If so, it adds +1" beside arrival Time. Example: If the destination is Dammam and departure Time is 02:15 → arrival Time is 03-20 If the destination is Jeddah and departure Time is 23:30 — arrival Time is 01:15+1 The following table shows the duration of time between Riyadh and each city: Duration 65 minutes City Dammam Jeddah, Yanbu and Abha Hail 105 minutes 75 minutes 80 minutes 95 minutes Tabuk Taif
printFlightInfo() It prints the information of a flight in the following format: Flight Number: flightNo Destination: destination Departure Time: departure Time Gate:gate Date: date Amival Time: arrival Time Setters + Getters as needed (shown in UML). + After that we need to implement some functions for the system. Before that, we need to declare 10 global objects of type Flight (11,2,3,... [10). The functions are as follows: . addFlight(string dest, int g, string d, string dep Tim) It adds the information of the received parameters to the next available flight object, starting from 11, 12,.., and so on. It then retums true if the add operation is completed successfully, and false otherwise. The flight is successfully added if the number of the current flights does not exceed 10, and if date and departure time has a correct format. The correct format for the date is /e and correct format for the for departure time is : • findFlight(string no) It returns the index of the flight with the received flight number no if found, and -1 otherwise. Knuwing that object fl has index 1, object 12 has index 2 and so on. . listFlights) It prints all flights" information in the list. It prints an appropriate message in case there is no flight • listFlightin Month(int m) lt prints all flights information that are departed in the received month. It prints an appropriate message in case there is no flight in that month. • update FlightTime(string no) It updates departure and arrival times of the received flight number no by reading departure time from user. It then validates it, if it follows the same format, and repeatedly asks the user to re-enter again in case it is invalid.The function updates the flight and prints an appropriate message after update in case the flight is found. Otherwise, it prints another message. • isValidNum(string str) It checks the received string str if valid or not. The string stris valid if it is consists of five characters, and both the first two characters and the last two characters are digits. The function returns true if str is valid, false otherwise. Now we reach the final step, which is festing your system in the main function. In the main function, a list will be repeatedly displayed to the user with the following options: 1. Add a flight 2. Find a flight 3. List all flights 4. List flights for a given month. 5. Update departure & arrival time. 6. Display the total number of flights. 7. Exit
(1) Read all information from user, and add it to the next flight object. Print an appropriate message to tell if the add operation is done successfully or not. (2) Ask the user to enter a flight number. Then, if found, print the flight index (fl has index 1,12 has index 2..etc.) along with the flight information. Print an appropriate message to tell if the flight is not found (3) List all flights information added to the system, if any. (4) Ask the user to enter a month and then list all flights information scheduled in that month, if any. (5) Ask the user to enter a flight number and the new departure time, then update the departure time (and arrival time accordingly) of that flight. (6) Display the number of total flights added. (1) Exit the system Important Points Date and departure time should be checked before adding the flight The flights are added in a sequence, first flight should be added to object fl and next one to object 12 and . Suppose that user will always enter valid data. No need to check user entry other than those mentioned previously. All flights are departing from Riyadh There is a counter for the number of flights, the totalFlights will be incremented whenever a flight is added Successfully Appropriate message should be displayed when the user chooses an invalid choice from the list. You need to search about converting strings to integers and vice versa! so on.
