- The function print_last_line in python takes one parameter, fname, the name of a text file. The function should open the file for reading, read the lines of the file until it reaches the end, print out the last line in the file, report the number of lines contained in the file, and close the file. Hint: Use a for loop to iterate over the lines and accumulate the count. For example: Test Result print_last_line("wordlist1.txt") maudlin The file has 5 lines.arrow_forwardShow two different ways to reset the file position pointer to the beginning of the filearrow_forward"NOTE: write an algorithm" You are given a file called “std” and composed of “Number, Name, Address” fields/attributes. (You can define the type of fields by yourself) Write an algorithm that makes “insertion, deletion, update and retrieve”, processes on the records in the file. The “Number” field is the key of each record.arrow_forward
- When you say a file is indexed, do you mean it has an index directory that allows for random access?arrow_forward"NOTE: write an algorithm pseudocode" You are given a file called “std” and composed of “Number, Name, Address” fields/attributes. (You can define the type of fields by yourself) Write an algorithm that makes “insert, delete, update and retrieve”, processes on the records in the file. The “Number” field is the key of each record.arrow_forwardThe function fopen return NULL when: An error occurred while opening the file. An error occurred while reading the file. An error occurred while closing the file. An error occurred while compiling the file.arrow_forward

(You can define the type of fields by yourself) Write an algorithm that makes “insert, delete, update and retrieve”, processes on the records in the file.

- INSTRUCTION: 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.arrow_forward"NOTE: write an algorithm, not a code" You are given a file called “std” and composed of “Number, Name, Address” fields/attributes. (You can define the type of fields by yourself) Write an algorithm that makes “insert, delete, update and retrieve”, processes on the records in the file. The “Number” field is the key of each record.arrow_forward(PYTHON) 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. Ex: If the input of the program is: ParkPhotos.txt and the contents of ParkPhotos.txt are: Acadia2003_photo.jpg AmericanSamoa1989_photo.jpg BlackCanyonoftheGunnison1983_photo.jpg CarlsbadCaverns2010_photo.jpg CraterLake1996_photo.jpg GrandCanyon1996_photo.jpg IndianaDunes1987_photo.jpg LakeClark2009_photo.jpg Redwood1980_photo.jpg…arrow_forward
