Write a program that gets 2 or more command-line arguments. The last argument is a file that the program will send its output to. The other arguments arenames of input files that already exist and that contain integers.The program opens each of the existing input files, in the order given by the arguments, and reads and sums all the integers of each file, writing the name of theInput file followed by its sum to the output file (given by the last argument).EXAMPLE: If the program were invoked like this: a.out fileA fileB filezzzand if the content of fileA was "398" and that of fileB "4 1" then the output written to filezzz would be:fileA 20fileb 51 of 1 Sun Mar 13 2022 1141:38 GMT-0400 (EDT)SUBMITRESETimport aysA out- open (sys.argv(-1), w) Here you are accessing the out put tile

Write 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! Sit! Sit! Sit! The following function call: inF = 'catInTheHat.txt' outF =…
The Payroll Department keeps a list of employee information for each pay period in a text file. The format of each line of the file is the following: <last name> <hours worked> <hourly wage> Write a program that inputs a filename from the user and prints to the terminal a report of the wages paid to the employees for the given period. The report should be in tabular format with the appropriate header. Each line should contain: An employee’s name The hours worked The wages paid for that period. An example of the program input and output is shown below:
Java Your program must read a file called personin.txt. Each line of the file will be a person's name, the time they arrived at the professor's office, and the amount of time they want to meet with the professor. These entries will be sorted by the time the person arrived. Your program must then print out a schedule for the day, printing each person's arrival, and printing when each person goes in to meet with the professor. You need to print the events in order of the time they happen. In other words, your output will be sorted by the arrival times and the times the person goes into the professor's office. In your output you need to print out a schedule. In the schedule, new students go to the end of the line. Whenever the professor is free, the professor will either meet with the first person in line, or meet with the first person in line if nobody is waiting. Assume no two people arrive at the same time. You should solve this problem using a stack and a queue. You can only…
Suppose you are given a text file that contains the names of people. Every name in the file consists of a first name and last name. Unfortunately, the programmer that created the file of names did not guarantee that each name was on a single line of the file. Read this file of names and write them to a new text file sorted according to first name, one name per line. For example, if the input file contains Ed Marston Bob Jones Jeff Williams Fred Charles The output file should be Bob Jones Ed Marston Fred Charles Jeff Williams Use arrays to solve the problem.
2. This involves a .txt file with one thousand rows of random numbers (between 1-1000) Using Python, create a program to perform this task, with 3 methods of doing this: Read the entire contents of file1.txt into memory, then process each row. Read one row of file1.txt at a time and process it. Split file1.txt into 2 parts and read each part into memory separately.

Given a set of text files containing synonyms for different words, complete the main program to output the synonyms for a specific word. Each text file contains synonyms for the word specified in the file’s name, and each row within the file lists the word’s synonyms that begin with the same letter, separated by a space. The program reads a word and a letter from the user and opens the text file associated with the input word. The program then stores the contents of the text file into a dictionary predefined in the program. Finally the program searches the dictionary and outputs all the synonyms that begin with the input letter, one synonym per line, or a message if no synonyms that begin with the input letter are found. Hints: Use the first letter of a synonym as the key when storing the synonym into the dictionary. Assume all letters are in lowercase. Ex: If the input of the program is: educatecthe program opens the file educate.txt, which contains: brainwash briefcivilize coach…

Write a C++ program that asks the user for a file name and a word for which to search. The program should search the file for every occurrence of the word. When the word is found, the line it contains should be displayed. After all of the occurrences have been found, the program should display the number of times the word was found in the file.
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 first reads the name of the text file from the user. The program then reads the text file, stores the information into four separate lists, and outputs the available food items 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'). Ex: If the input of the program is: food.txt and the contents of food.txt are: Classic ham sandwich Available sandwich Chicken salad sandwich Not available Classic cheeseburger Cheeseburger Not available Salads Water 16oz bottled water Available Caesar salad Chunks of romaine heart lettuce dressed with lemon juice Available Salads Asian salad Mixed greens with ginger dressing, sprinkled with sesame Not available Beverages Beverages Mexican food…
