2. File handling is an important part of any application. Assume that, you are asked to
build an application to find the harmonic mean in a file. Assume that you have to read
the file of "Filel.txt" and print the harmonic mean of each row to an output file
"File2.txt". All of the data in the "File1.txt" is comma separated. In file1.txt you are
given the name of the data set in first place, then you are given the data list. All of them
are comma separated. Your task is to compute the harmonic mean from the given file
| for each dataset. The file may contain more than 1000 rows. Write your code by
following the requirements.
File2.txt
harmonic mean of Datal is 3.50
harmonic mean of Data2 is 3.43
harmonic mean of Data3 is 3.50
File1.txt
Data1, 3, 4, 4, 3, 3.7, 4, 3.3, 1
Data2, 3, 4, 3.7, 3, 3.7, 4, 3, 1
Data3, 3, 4, 4, 3, 3.7, 4, 3, 2

- Given a text file containing the availability of food items, write a program that reads the information from the text file and outputs the available food items. The program should first read the name of the text file from the user. The program then should read the text file, line by line. If a food is available, the program should output the available food item in the following format: name (category) -- description Assume the text file contains the category, name, description, and availability of at least one food item, separated by a tab character ('\t'). Hints: Use the find() function to find the index of a tab character in each row of the text file. Use the substr() function to extract the text separated by the tab characters. Ex: If the input of the program is: food.txt and the contents of food.txt are: Sandwiches Ham sandwich Classic ham sandwich Available Sandwiches Chicken salad sandwich Chicken salad sandwich Not available Sandwiches Cheeseburger Classic cheeseburger Not…arrow_forward1. Write a program that opens an output file with the filename my_name.txt, writes your name to the file, then closes the file. 2.

Write code that does the following: opens an output file with the filename number_list.arrow_forwardWrite a function named repeat_words that takes two string parameters: 1. in_file: the name of an input file that exists before repeat_words is called 2. out_file: the name of an output file that repeat_words creates Assume that the input file is in the current working directory and write the output file to that directory. For each line of the input file, the function repeat_words should write to the output file all of the words that appear more than once on that line. Each word should be lower cased and stripped of leading and trailing punctuation. Each repeated word on a line should be written to the corresponding line of the output file only once, regardless of the number of times the word is repeated. For example, if the following is the content of the file catInTheHat.txt: Too wet to go out and too cold to play ball. So we sat in the house. We did nothing at all. So all we could do was to Sit!

Your should use C++ streams to create a copy of this file with the name as the original program file name concatenated with "_copy" and then the original extension (e.g., "input_copy.txt").

For example, the following would be the correct input and output:>>> file_stats('created_equal.txt')lines 2words 13characters 72Note: The number of characters may vary slightly between operating systems.

PROGRAM DESIGNThe program should be able to accept an integer input. This program should be able to open and read a file called tweets2.txt. The integer input represents the order of the line (from 1st to 5th line), within the tweets2.txt file. The program should be able to count how many stopwords, common words, unique words, and overall words are there in the line number input. In Natural Language Processing (NLP), stopwords are defined to be words with no meaning when left alone and with no context. For this activity, stopwords are words that are at most, 3 characters in length, with common words having more than 3 characters. Unique words are words, within the line, that don’t have any duplicates. Whereas overall words are the over all count of all words within the line.
