Homework Assignment (read instructions carefully) Write a program that asks the user for the name of a file. The program should read all the numbers from the given file and display the total and average of all numbers in the following format (three decimal digits): Total: nnnnn.nnn Average: nnnnn.nnn Class name: FileTotalAndAverage Here is a working code but please modify it so it passes the test cases because I run it it does not work: Also I do not need Goodbye.

- Assuming that a text file named FIRST.TXT contains some text written into it, write a function namedcopyupper(), that reads the file FIRST.TXT and creates a new file named SECOND.TXT contains allwords from the file FIRST.TXT in uppercase. (write c++ code)arrow_forwardWrite a write_scores function that opens the file, and writes scores and names from lst_scores and lst_names into the file. An example function call is below. Make sure to handle a file error. Assume good input in both lists. Function name: write_scoresParameters: lst_scores, a list of ints; lst_names, a list of strings; file_name, a string Purpose: Writes the names and scores to the file name, with one name and one corresponding score per line.Example function call: (attached) After this code runs, the file final_grades.txt should read: Ayesha 96 Paolo 99 Ahmed 93 Anna 94arrow_forward12.7: Sentence Filter C++Write a program that asks the user for two file names. The first file will be opened for input and the second file will be opened for output. (It will be assumed that the first file contains sentences that end with a period.) The program will read the contents of the first file and change all the letters to lowercase except the first letter of each sentence, which should be made uppercase. The revised contents should be stored in the second file. Prompts And Output Labels. Input Specification. Instructor Notes: The input/output should consist of: cout << "Enter the input file name: ";cin >> inName;cout << "Enter the output file name: ";cin >> outName;arrow_forward
- The objective of this question is to generate and read files that contain a list of random numbers. Write a function that generates a file with following parameters: def fillFile(fileSize, fileName): The function should be called to generate files in the following sizes: fileSizes = [1000, 5000, 10000, 20000, 30000, 40000, 50000] The generated files can have names file1000, file 5000, file 10000, file20000, fi130000, file40000, file 50000. You can use random.randint(0.fileSize+1000) to generate a random number. Write another function that reads numbers inside of a file and returns a list. def readFile(fileName): The returned list contains the numbers stored in the file. At each call of fillFile and readFile, record the times before and after the function call as in following example (import time): start = time.time() fillFile(file Size, "file" + str(fileSize)) finish time.time() runTime = finish - start Record the run times of functions into a file named "fileStats.txt".

Write a program that reads the name of a text file containing a list of photo file names. The program then reads the photo file names from the text file, replaces the "_photo.jpg" portion of the file names with "_info.txt", and outputs the modified file names. Assume the unchanged portion of the photo file names contains only letters and numbers, and the text file stores one photo file name per line. If the text file is empty, the program produces no output. Ex: If the input of the program is: ParkPhotos.txt and the contents of ParkPhotos.txt are: Acadia2003_photo.jpg AmericanSamoa1989_photo.jpg BlackCanyonoftheGunnison1983_photo.jpg CarlsbadCaverns2010_photo.jpg CraterLake1996_photo.jpg GrandCanyon1996_photo.jpg IndianaDunes1987_photo.jpg LakeClark2009_photo.jpg…arrow_forwardCode should be in Python.

- The __________ member function returns a file’s current write position.arrow_forwardChapter 4. PC #6. File Letter Counter (page 264) Write a program that asks the user to enter the name of a file, and then asks the user to enter a character. The program should count and display the number of times that the specified character appears in the file. Class name: FileLetterCounter Hints: Hint 1. To read a single character from the keyboard, you need to read a full line and then take the first character in position 0. Hint 2. To count the occurrences of a given characters in a file you need to read the file line-by-line using a while loop, then for each line check all characters in all positions and increment the character counter for each occurrence. This will require to have a for-loop nested inside the while-loop. Here is a working code Please modify it so it passes the test cases because I run it it does not work: mport java.io.File;import java.io.FileNotFoundException;import java.util.Scanner;public class FileRead {public static void main(String[] args)…arrow_forwardChapter 4.
