- When you open a file for reading, what happens if the file does not exist? When you open a file for writing, what happens if the file already exists?Write C++ code to read a list of integers from a file until the end of the file is reached. When the entire file has been read, print the sum of the numbers that were read. Include declarations for all variables that you use, including the file object, and be sure to open and close the file (you can make up the file name). Assume that the integers are each on a new line.What happens if the file already exists when you open a file for output?
- How do you create an object for reading data from file test.txt? How do you create an object for writing data to file test.txt?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 FalseCan you help/guide me on this assignment, here are the directions: Write a program that reads words from a text file and displays all the words (duplicates allowed) in ascending alphabetical order. The words must start with a letter. The text file is passed as command-line argument (you can assume that the text file is in the same directory as the executable, i.e. bin). I think the code is correct but I believe what I'm doing wrong is the Command line argument where I'm placing the text file. Which I think is in the right place, apparently not. Here's my work:
- Can you help me write a C++ Program that does the following: Create a program that reads a file containing a list of songs andprints the songs to the screen one at a time. 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 andquit. If there were no songs in the file to begin with, the program shouldsay 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 the latest version of the class Song you created. The latest version of the class song I created is below: #include <iostream>#include <string>using namespace std;class Song {private: string Title; string Artist; int Year;public: Song() : Title("invalid"), Artist("invalid"), Year(-1) {} Song(const string…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.In C++, my program reads from a file, each line of the text file ends in a 1 or 0. How do you make a function that updates the value in the text file to change to from 1 to 0 or 0 to 1?
- <<Write in Java>> - Challenge 7 File encryption is the science of writing the contents of a file in a secret code. Your encryption program should work like a filter, reading the contents of one file, modifying the data into a code, and then writing the coded contents out to a second file. The second file will be a version of the first file, but written in a secret code. Although there are complex encryption techniques, you should come up with a simple one of your own. For example, you could read the first file one character at a time, and add 10 to the character code of each character before it is written to the second file. - Challenge 8 Write a program that decrypts the file produced by the program in Programming Challenge 7. The decryption program should read the contents of the coded file, restore the data to its original state, and write it to another fileWrite the code completely.(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…
