- (Inventory) Create an ASCII file with the following data, or use the shipped.dat file available on this book’s Web site. The headings aren’t part of the file but indicate what the data represents Using this data file, write a C++ program that reads the file and produces a report listing the shipped date, part number, first name, last name, and company name.arrow_forward(Data processing) Write a C++ program that allows the user to enter the following information from the keyboard for each student in a class (up to 20 students): Name Exam 1 Grade Exam 2 Grade Homework Grade Final Exam Grade For each student, your program should first calculate a final grade, using this formula: FinalGrade=0.20Exam1+0.20Exam2+0.35Homework+0.25FinalExam Then assign a letter grade on the basis of 90100=A,8089=B,7079=C,6069=D, and less than 60=F . All the information, including the final grade and the letter grade, should then be displayed and written to a file.arrow_forward(Misc. application) Four experiments are performed, and each experiment has six test results. The results for each experiment are given in the following list.

- pls code in pythonplagiarism: This Boolean function takes two filenames. If any line occurs in both files, return True.If not, return False. I suggest using nested loops. With nested loops, we call the loop that is in thebody of the other loop, the "inner loop". The loop that contains the inner loop is the "outer loop". Openthe second file inside the outer loop:for line1 in file1:file2 = open(fname2)for line2 in file2:Python only lets you read the file once per open, so you need this order of instructions. Make sure yourreturn False is outside of both loops. Otherwise, you will only compare the first two lines of thefiles. Make sure you close the file that gets read repeatedly after the inner loop but still inside the outerloop.Here is some (more complete) pseudocode to get you started:open file 1for line1 in file 1open file 2for line2 in file 2:if line1 == line2:return Trueclose file 2return Falsearrow_forwardFinish this program from the code posted below! Note: There should be two files Main.py and Contact.py You will implement the edit_contact function. In the function, do the following: Ask the user to enter the name of the contact they want to edit. If the contact exists, in a loop, give them the following choices Remove one of the phone numbers from that Contact. Add a phone number to that Contact. Change that Contact's email address. Change that Contact's name (if they do this, you will have to remove the key/value pair from the dictionary and re-add it, since the key is the contact’s name. Use the dictionary's pop method for this!) Stop editing the Contact Once the user is finished making changes to the Contact, the function should return.

Write a program that displays a concordance for a file. The program should output the unique words and their frequencies in alphabetical order. Variations are to track sequences of two words and their frequencies, or n words and their frequencies. Below is an example file along with the program input and output: example.txt I AM SAM I AM SAM SAM I AMarrow_forward
- Write 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_forwardThe program takes a single argument as the name of the file to be read. A sample file is named (Movies.txt). The program reads this file which has labeled columns separated by commas. Every row of this text file includes information about a movie. You are asked to read every row as a string and decompose the given information (separated by commas). If a costumer wants too see "List of the Genres" (or genre,score,year) all genres type must be show. I need this answer in C language. Please explain nicely. Thanks.arrow_forwardPYTHON!!!! Write a program that allows the user to navigate the lines of text in a file. The program should prompt the user for a filename and input the lines of text into a list. The program then enters a loop in which it prints the number of lines in the file and prompts the user for a line number. Actual line numbers range from 1 to the number of lines in the file. If the input is 0, the program quits. Otherwise, the program prints the line associated with that number. An example file and the program input and output is shown below: example.txt Line 1. Line 2. Line 3. Enter the input file name: example.txt The file has 3 lines. Enter a line number [0 to quit]: 2 2 : Line 2. The file has 3 lines. Enter a line number [0 to quit]: 4 ERROR: line number must be less than 3. The file has 3 lines. Enter a line number [0 to quit]: 0 The program works as expected for given input, test 1: Custom Test: Delete file at start Test Contents: import os.path try: os.remove('.test.txt')…arrow_forward

After each song is printed, except for the last song, the program asks the user to press enter for more. After the last song, the program should say that this was the last song and quit. If there were no songs in the file to begin with, the program should say that there are no songs to show and quit. The program should begin by asking the user for the name of the input file. Each song consists of a title, artist, and year. In the file, each song is given on three consecutive lines. Create this program using a class Song.arrow_forwardVirus DNA files As a future doctor, Jojo works in a laboratory that analyzes viral DNA. Due to the pandemic During the virus outbreak, Jojo received many requests to analyze whether there was any viral DNA in the patient. This number of requests made Jojo's job even more difficult. Therefore, Jojo ask Lili who is a programmer for help to make a program that can read the file containing the patient's DNA data and viral DNA and then match them. If on the patient's DNA found the exact same string pattern, then write to the index screen the found DNA. Data contained in the file testdata.in Input Format The first line of input is the number of test cases TThe second row and so on as many as T rows are the S1 string of patient DNA and the S2 string of viral DNA separated by spaces Output Format The array index found the same string pattern.
