- (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.C++: Matching Program Create a datafile that contains the first name, last name, gender, age, height, smoking preference, eye color and phone number. Add a variety of records to the file. A sample file looks like: Write a program that opens the file and reads the records one by one. The program will skip any records where the gender preference is not a match. Of those records that match the gender preference, check to see if the age and height are between the maximum and minum preferences. Then check to see if the smoking preference and eye color are also a match. If at least 3 of the remaining fields match, consider the record a partial match, and print it in the report. If all 4 of the remaining fields match, the record is a perfect match and print it in the report with an asterisk next to it. At the end of the program, close the file and report how many total records there were of the specified gender, how many were a partial match, and how many were a perfect match. See the…question] ll-based questions 1. Write a program that takes a person's details (name, age and a city), and writes to a file (persons.txt) using a loop repeatedly. The program terminates on entering any key by the user, except on (Y or y) key. Sample output of the first run of the program is shown below: Enter name: John Enter age: 20 Enter city: Sydney Data saved: John 20 Sydney Press (Y or y) to add another person, or any key to exit A Education 302 Elizabeth Street, Sydney http://www.win.edu.au/ }
- Subject :computer sciences language : c ++ Question : write a program in c++ in which the main program ask user for the number of students whose records must be inserted in file(file handling ). Afterwards, take records from user, calculate grade of students and store all records in a file. paste the screen record of the file and also the outputs.The function file_first_chars in python takes one parameter, fname, the name of a text file, and returns a string made up of the first character from each line in the file. You may assume there are no blank lines in the file. Hint: Use a for loop to iterate over the lines of the file and accumulate the string of first characters. NOTE: Return the function, don't print For example: Test Result print(file_first_chars("wordlist1.txt")) hsaemThis Python Lab 9 Lab: Write a file copying program. The program asks for the name of the file to copy from (source file) and the name of the file to copy to (destination file). The program opens the source file for reading and the destination file for writing. As the program reads each line from the source file and it writes the line to the destination file. When every line from the source file has been written to the destination file, it close both files and print “Copy is successful.” In the sample run, “add.py” is the source file and “add-copy.py” is the destination file. Note that both “add-copy.py” is identical to “add.py” because “add-copy.py” is a copy of “add.py”. Sample run: Enter file to copy from: add.py Enter file to copy to : add-copy.py Copy is successful. Source file: add.py print("This program adds two numbers") a = int(input("Enter first number: ")) b = int(input("Enter second number: ")) print(f"{a} + {b} = {a+b}") Destination file:…
- The Spring fork amateur golf club has a tournament every weekend. The club president has asked you to design a program. It contains the following menu: Select the task 1. Add new records 2. Read Records 3. End the program If the user enters 1, the program will read each players name and golf score as keyboard input, then save the records in a file names golf.dat If the user enters 2, the program reads the records from the golf.dat file and displays them. While the menu selection is not equal to 3, get the user selection. If the selection is 1, get the number of players in the tournament, open the output file. For each player, get the name and the score, and write them to the file. Close the file. If the selection is 2, open the input file, read the values from the file, display the values, close the file. If the selection is 3, exit the program. I already had a code written from before, but I'm having a hard time turning it into a menu driven code. It does need to have the function…please code in python count_word: This function takes a filename and a keyword. Return the number of times the keywordoccurs in the file. Initialize a variable to keep track of the number of times the keyword appears.Traverse the file by line. Use the count method on each line to find the number of times the keywordappears in it and add that amount to the variableINSTRUCTION: C++ Language Create a function that writes to a file named Inventy.txt the information of 8 items. Ask the user for the item's name, the item's quantity in storage, and the item's price and write it to the file. Create a function that reads the file and items' quantity and price to two different arrays. Create a function that computes the subtotal of each item. Implement all functions inside the main program and the computed value should be displayed with the item's name.
- C programming language Criteria graded: Declare file pointers Open file Read from file Write to file Close file Instructions: Write a segment of code that opens a file called “numbers.txt” for reading. This file is known to have 10 numbers in it. Read in each number and print a ‘*’ to the screen if the number is even. If the number is odd, do nothing. Conclude by closing this file.JAVA PPROGRAM Write a program that prompts the user to enter a file name, then opens the file in text mode and reads names. The file contains one name on each line. The program then compares each name with the name that is at the end of the file in a symmetrical position. For example if the file contains 10 names, the name #1 is compared with name #10, name #2 is compared with name #9, and so on. If you find matches you should print the name and the line numbers where the match was found. While entering the file name, the program should allow the user to type quit to exit the program. If the file with a given name does not exist, then display a message and allow the user to re-enter the file name. The file may contain up to 100 names. You can use an array or ArrayList object of your choosing, however you can only have one array or ArrayList. Input validation: a) If the file does not exist, then you should display a message "File 'somefile.txt' is not found." and allow the…A car dealer needs a program that will maintain an inventory of cars on the lot. There are three types of cars: sedans, station wagons, and SUVS. The model, year, color, and price need to be recorded for each car, plus any additional features for the different types of cars. The program must allow the dealer to: • Add a new car to the lot Remove a car from the lot • Correct any data that's been entered • Display information for any car The software developer decides to have these classes: Car, Inventory, Sedan, SUV, and StationWagon. Choose the correct answer after considering the following statements: 1. There are no inheritance relationships between these classes. 2. The Inventory class has-a list of Car objects. 3. The Sedan, StationWagon, and SUV classes are independent of each other. O Only 1 and 2 are true O Only 2 is true O Only 2 and 3 are true O Only 1 is true O Only 3 is true
