Transcribed Image Text:o display Aircraft()- This method accepts a regNumber and searches the array for an
aircraft that matches that regNumber and displays the information about that
vehicle.
o removeAircraft()- This method accepts a regNumber and searches the array for that
aircraft. For each item that doesn't match, it will copy the contents to the new
array. It will not copy the contents of the aircraft that is found. In other words, all
aircraft in the array will be moved up a position to fill in the gap in the array.
nu class:
stance Variables:
o An array that stores all of the menu item options
Transcribed Image Text:Fleet class:
Instance Variables
An array that stores Aircraft that represents Delta Airlines entire fleet
A variable that represents the count for the number of aircraft in the fleet
Methods:
o Constructor-One constructor that instantiates the array and sets the count to aero
readFile()-This method accepts a string that represents the name of the file to be
read. It will then read the file. Once the data is read, it should create an aircraft and
then pass the vehicle to the addAircraft method. It should not allow any duplication
of records. Be sure to handle all exceptions.
o writeFile()-This method accepts a string that represents the name of the file to be
written to and then writes the contents of the array to a file. This method should
call a sort method to sort the amay before writing to it.
sortArray()-This method returns a sorted array. The array is sorted by registration
number.u
addAircraft- This method accepts an aircraft and adds it to the fleet(the array only
if it is not already in the list.
displayFleet)-This method outputs all of the ships and shuttles that are in the fleet.
o display Maintenancetist()-This method outputs all aircraft in the array that currently
require maintenance, either by miles or date.
o displayNextMaintenancetist() This method outputs all aircraft in the fleet by
name, manufacturer, model, next maintenance date, and next maintenance miles
o updateMiles) This method accepts a regNumber and miles and updates the total
miles for the designated aircraft based on regNumber
update Maintenance()- This method accepts a regNumber and changes the
lastMaintenance date to the current date and resets last maintenance mileage

- CMPSC 125: C++ Programming Programming Project Assignment Program Description: This assignment focuses on while loops and random numbers. Turn in a file named Lab4_yourFirstName.cpp. Your program allows the user to play a game in which the program thinks of a random integer and accepts guesses from the user until the user guesses the number correctly. After each incorrect guess, you will tell the user whether the correct answer is higher or lower. The below shows one sample execution of your program. Your output will differ depending on the random numbers chosen and user input typed, but the overall output structure should match that shown below: I am thinking of a number between 1 and 100 Your guess? 50 [Enter] It's lower Your guess? 25 [Enter] It's higher Your guess? 35 [Enter] It's lower Your guess? 30 [Enter] It's higher Your guess? 32 (Enter] It's lower Your guess? 31 [Enter] You got it right in 6 guesses!

Note: Save text below as the file to use and name it forChap12.txt file for this assignment. Text: No one is unaware of the name of that famous English shipowner, Cunard. In 1840 this shrewd industrialist founded a postal service between Liverpool and Halifax, featuring three wooden ships with 400-horsepower paddle wheels and a burden of 1,162 metric tons. Eight years later, the company's assets were increased by four 650-horsepower ships at 1,820 metric tons, and in two more years, by two other vessels of still greater power and tonnage. In 1853 the Cunard Co., whose mail-carrying charter had just been renewed, successively added to its assets the Arabia, the Persia, the China, the Scotia, the Java, and the Russia,…arrow_forwardMicrofost Visual C# 7th edition programming exercise 6-10. I need help, please. This problem relies on the generation of a random number. You can create a random number that is at least min but less than max using the following statements: Random ranNumberGenerator = new Random();int randomNumber;randomNumber = ranNumberGenerator.Next(min, max); Create a game similar to Hangman named GuessAWord in which a player guesses letters to try to replicate a hidden word. Store at least eight words in an array, and randomly select one to be the hidden word. Initially, display the hidden word using asterisks to represent each letter. Allow the user to guess letters to replace the asterisks in the hidden word until the user completes the entire word. If the user guesses a letter that is not in the hidden word, display an appropriate message. If the user guesses a letter that appears multiple times in the hidden word, make sure that each correct letter is placed. Figure 6-27 shows a typical game…arrow_forward
