- question 2arrow_forwardAssignment 5C: Level Map Creator. There are a variety of ways that game developers store their level layouts. One simple method is to associate level elements with certain symbols, and then storing them in a 2D grid inside a text file. We will use our knowledge of 2D arrays to create a very simple Level Map Creator tool. The program should prompt the user to enter a width and height for the level. Then it should initialize a 2D array and fill every element with the *" symbol. Afterwards, the user should be given the following options via a menu: 1. Clear Level 2. Add Platform Prompt the user to enter a starting point and length for the Re-initialize the 2D array and fill every element with the "** symbol. horizontal platform. Replace those elements in the 2D array with the "=" symbol. If the length is longer than the number of columns |(or out of bounds), notify the user that this is not possible. Prompt the user to enter a column and row index. Replace that element in the 2D array…arrow_forwardDescription Create an application that maintains an array of your home inventory and displays the contents of the array in a list box. For this assignment, we will be using an array. In later chapters, we will modify this application to use a database or an external text file. The application should look like: g My Home Inventory Home Inventory Item Description Ist Homelnventory Serial Number Cost ADD DELETE REFRESH BYE Detailed Instructions 1. Define arrays for Item Description, Serial Number, and Cost after the Public Form Q and before any click of page load events. 2. In the Page Load Event, populate the Home Inventory List Box with the data from the arrays using the format: "ItemDecription (SerialNumber, Cost)". 3. If the ADD button is clicked, add the Item Description, Serial Number, and Cost to the Home Inventory List Box and to the appropriate arrays. 4. If the DELETE button is clicked, remove the item from the Home Inventory List Box and corresponding arrays. 5. If the REFRESH…arrow_forward
- C++ Visual Studio 2019 Write a program that opens a specified text file then displays a list of all the unique words found in the file. Addition to the text book specifications, print the total of unique words in the file. Hint: Store each word as an element of a set. 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_forward4. An array named nums contains the following numbers: 5, 10, 15. It is declared as follows: box const nums = [5, 10, 15]; Write the necessary code to display each item in the array in an alert using a for loop?arrow_forwardUsing C# in Microsoft Visual Studio Create an application that simulates a game of tic-tac-toe. The application should use a two-dimensional int array to simulate the game board in memory. When the user clicks the New Game button, the application should step through the array, storing a random number in the range of 0 through 1 in each element.The number 0 represents the letter O, and the number 1 represents the letterX. The form should then be updated to display the game board. The application should display a message indicating whether player X won, player Y won, or the game was a tie.arrow_forward

The program should allow the user to enter each student's name and his or her four test scores. It should then calculate and display each student's ayerage test score and a letter grade based on the average. Input Validation: Do not accept test scores less than 0 or greater than 100.

- Chapter 7 - Programming Challenge 15 15. World Series Champions If you have downloaded this book’s source code (the companion Web site is available at www.pearsonhighered.com/gaddis), you will find a file named WorldSeriesWinners.txt. This file contains a chronological list of the winning teams in the World Series from 1903 through 2009. (The first line in the file is the name of the team that won in 1903, and the last line is the name of the team that won in 2009. Note that the World Series was not played in 1904 or 1994, so those years are skipped in the file.) Write a program that lets the user enter the name of a team, and then displays the number of times that team has won the World Series in the time period from 1903 through 2009. Tip: Read the contents of the WorldSeriesWinners.txt file into an ArrayList. When the user enters the name of a team, the program should step through the ArrayList, counting the number of times the selected team appears You only need to submit the…arrow_forwardWrite a For Each loop that displays every element of an array named strSongNames in a ListBox named lstDisplay.

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.
