Lab03-08. We can erase data elements from a random file because the connected stream in memory is in fact an array. Weerase a data item by shifting the rest of the items one position toward the beginning of the stream. However, shiftingcreates a duplicate data item at the end. In an array, we reduce the size to avoid using that duplicate. In the case of astream, we must change the last element to a dummy. We know that a file of characters can be accessed randomlybecause the size of a character is fixed. Assume that you have the following file of characters:ABCDEFGHIJKLMNOPQRSTUVWXYZWrite a program that erases any character in the file given its position (0 to 25). Remember to change the duplicatecharacter in the end to a null character.

According to the question, We have to write code to erase data elements from a random file because…

/*TASK 5. Implement part 1 of the report. You need to read data from input.txt file, store it into array of items (called items) and write it in a formatted form to the output file. Code, debug and present it in the best possible format. Hint: It might be helpful to format the String coming from toString( ) method using String.format( ) method, which works similar to System.out.prinf. Hint2: You might have to close and delete existing output .doc or .txt file from its folder * public class YourUserName_hw7 { static Item [ ] items = new Item [200];//an array of Items static EdibleItem [ ] edibleItems;//an array of Edible Items static int countEdibleitems = 0;//count edible items static String pageHeader; //save the header //main( ) method runs the program public static void main(String[ ] args) throws FileNotFoundException { double sum = 0, average = 0; //Optional - create a new input file //CreateInput.createInputFile( );…
Program 12_2.java Write a program that creates a small (6-10) array of ints. Display your array elements, all on one line, using a foreach loop. In a try block, prompt the user to enter an index for the array and attempt to print the element with that index. Follow the try block with two catch blocks; one that detects an index out of bounds, and another that catches other bad inputs. See Sample Runs below. Sample Run 112 15 24 5 9 16 Enter any index of your array 5 Element at index 5 is 16 Sample Run 212 15 24 5 9 16 Enter any index of your array 9 Error.

Create a file named histogram.js. Write a program that will allow me to enter numbers between 1 and 100. I will enter numbers until I enter 0. Iterate over the array and display a histogram for the numbers entered. Don't overcomplicate the histrogram piece. Displaying the histogram only involves printing an asterick for the number of times a number is contained in the array. I need to write this program using const readline = require('readline');
Write a program that reads movie data from a CSV (comma separated values) file and output the data in a formatted table. The program first reads the name of the CSV file from the user. The program then reads the CSV file and outputs the contents according to the following requirements: Each row contains the title, rating, and all showtimes of a unique movie. A space is placed before and after each vertical separator ('|') in each row. Column 1 displays the movie titles and is left justified with a minimum of 44 characters. If the movie title has more than 44 characters, output the first 44 characters only. Column 2 displays the movie ratings and is right justified with a minimum of 5 characters. Column 3 displays all the showtimes of the same movie, separated by a space. Each row of the CSV file contains the showtime, title, and rating of a movie. Assume data of the same movie are grouped in consecutive rows. Hints: Use the find() function to find the index of a comma in each row of…
Write a function that reads all the numbers from a file into an array. The file is already open and there is no bad data in the file. The data is one number per line and an unknown number of lines of data. The function should read data until either end of file is detected or the array is full. Prototype void readData( ifstream& iFile, double numbers[ ], int size, int& count); iFile - already open ifstream numbers[ ] - array to store data size - the size of the array. count - the number of values read and must be set by the function before returning.

What is the best way to implement a dynamic array if you don't know how many elements will be added? Create a new array with double the size any time an add operation would exceed the current array size. Create a new array with 1000 more elements any time an add operator would exceed the current size. Create an initial array with a size that uses all available memory Block (or throw an exception for) an add operation that would exceed the current maximum array size.
In java Browse Project Gutenberg (https://www.gutenberg.org/) for plain text versions of one or more works of literature of your choosing. Write a program that repeatedly searches a file for a target word or phrase.• Allow the user to supply the name of the file to search by means of a command-line argument; if the user does not supply a command line argument, ask for a file name interactively.• You may use either an array or an ArrayList to store each line in the file; but if you use an array, you’ll have to determine the array size (number of lines) before allocating the array. There are several ways to do this.• Report how many lines were read from the file.• Search for either individual words or phrases (Hint: use the .contains method, it’ll work for either a word or a phrase)• Show both the line number and the line itself for each line that contains the search target entered by the user (you may count the first line in the file as line 0).• If a search word is part of a larger…

Write a program to allow a user to play the game, Hangman. DO NOT USE AN ARRAY The program will generate a random number (between 1 and 4581) to pick a word from the file - this is the word you then have to guess. Note: if the random number you generate is 42, you need the 42nd word - so loop 41 times picking up the word from the file and not doing anything with it, it is the 42nd you need. Here is how you will do this: String word: for (int k=0; k<41; k++) {word=scnr.nextLine(); }//end loop and now pick up the word you want word=scnr.nextLine() //this is the one you want The user will be allowed to guess a letter as many times as it takes - but 10 wrong guesses and they lose!! Eventually either they won or lost. In case they lost print out the answer. Java
