- (Data processing) a. Write a C++ program that opens a file and displays its contents with line numbers. That is, the program should print the number 1 before displaying the first line, print the number 2 before displaying the second line, and so on for each line in the file. b. Modify the program written in Exercise 6a to list the file’s contents on the printer assigned to your computer.arrow_forwardFile redirection allows you to redirect standard input (keyboard) and instead read from a file specified at the command prompt. It requires the use of the < operator (e.g. java MyProgram < input_file.txt) True or Falsearrow_forwardA file concordance tracks the unique words in a file and their frequencies. 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.arrow_forward
- (C Language) A photographer is organizing a photo collection about the national parks in the US and would like to annotate the information about each of the photos into a separate set of files. 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. Assume also the maximum number of characters of all file names is 100.arrow_forwardWord List File WriterWrite a program that asks the user how many words they would like to write to a file, andthen asks the user to enter that many words, one at a time. The words should be writtento a file. (in phyton)arrow_forwardItem Counter Assume that a file containing a series of names (as strings) is named names.dat and exists on the computer’s disk. Design a program that displays the number of names that are stored in the file. (Hint: Open the file and read every string stored in it. Each time you read a string, increment a counter variable. When you’ve read all the strings from the file, the counter variable will contain the number of names stored in the file.)arrow_forward
- 1. 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 a program that opens the my_name.txt file that was created by the program in problem 1, reads your name from the file, displays the name on the screen, then closes the file. Write code that does the following: opens an output file with the filename number_list.arrow_forwardTrue or FalseAs items are read from the file, the read position moves forward, toward the end of the file.arrow_forwardC++Inventory Program Write a program that uses a structure to store the following inventory data in a file: Item Description Quantity on Hand Wholesale Cost Retail Cost Date Added to Inventory The program should have a menu that allows the user to perform the following tasks: • Add new records to the file. • Display any record in the file. • Change any record in the file. Input Validation: The program should not accept quantities, or wholesale or retail costs, less than 0.The program should not accept dates that the programmer determines are unreasonable.arrow_forward
- (FRP7) Write a function that reads data from a file. The file has already been opened and verified. The data should be saved in the array of type ship. The size of the array is passed in the int parameter and the number of records read is return in the last parameter, by reference. The file should be read until end of file has been reached or the array is full. struct ship{ string shipCaptain; string shipName; }; The function prototype isvoid readFile( ifstream&, ship[ ], int, int& ); ifstream - The already open file ship[ ] - array of structs where the data from the file will be stored. int - the size of the array. int& - the number of records read from the file. This value is set by the function before returning return- the number of records read from the file, returned by the function. The amount of data in the file is unknown but there is no bad data. The file format is the shipsName followed by the shipsCaptiain . Example: MillenniumFalcon HansSoloarrow_forwardplease 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 variablearrow_forwardCODE IN PYTHON PLEASE The objective is to create a code in Python that can extract the columns highlighted in blue (Column T and AB3) and output them to a .txt file. The code should be able to generate the text file with the columns that are highlighted in blue and store them on a separate folder. Below shows how the Test.xlsm file looks like as well as how the text file should look like when the code extracts and outputs it. Google drive to access Test.xlsm file: https://drive.google.com/drive/folders/16utzb5_h7yMCN8_13E_JqasfcpykZOYr?usp=sharing What my code outputs is shown in the picture (O1.png) What I would like for my code to output is the columns next to each other (Right Example.png) The current code is able to output Columns T and AB3 but I am not able to output them next to each other as shown above. We would also like for the code to be capable of storing the text file to a separate folder. Below is the code I have been working on. #package to read xlsm file import openpyxl…arrow_forward
