- C++ please use file names belowarrow_forwardWrite a C++ program: Question: Make 3 text files that includes numbers inside of them. Then ask the user which file do you want me to open and then validate the file. if the file exists you have to print the following message: "The file you requested exists, what number are you looking for?" otherwise you print the following message" "Sorry the file that you requested does not exist" if the file exists, then read the number that user enters and search in the files. if the number exists in the file, print the following message: "The number you requested is in this file." otherwise: "The number you requested does not in this file." Note: Again, do the above question without using array.arrow_forwardGiven the following, write a code SEGMENT that does the following: Creates a string variable to store a file name (to be entered by the user) Requests the input file name from the user and stores the name in a variable Opens the input file using the entered file name Tests the STATE of the file open. If the file does not open, output a message to the user exit the program Be sure to: Include the necessary header files Declare necessary variablesarrow_forward

The function can be called as follows: createFile(filename, n) main function, in which the user inputs the file name and the number of students, then the main calls function createfile. the main should preform validation for n (should be > 0), and the filename(should end with .txt)arrow_forwardUsing Pythonarrow_forward
- IT 280 - Lab \#2: Guessing Game (Rock, Paper, Scissors, Lizard, Spock) Instructions To Submit This Program In IDLE, choose File -> NewFile. Type your program in the window that pops up, saving it as you work. The file name should be your Last Name, followed by Lab 2.2.py in a Python program. Test the program by running it (F5 or Run→Run Module). Program Inputs: Ask the user for their choice (Rock, Paper, Scissors, Lizard, Spock) - (This can be done through a menu choice or in any other way). The program will randomly choose one of the five possibilities. (Generate random numbers in Python). The program will generate the winner and an appropriate statement based on the following:✓Rock crushes Lizard✓Rock destroys Scissors✓Paper disproves Spock✓Paper covers Rock✓Scissors cuts Paper✓Scissors decapitate Lizard✓Lizard eats Paper✓Lizard Poisons Spock✓Spock smashes Scissors✓Spock vaporizes Rock The user will then be asked if they want to play again, and the process repeats until they…arrow_forwardPYTHON i understand this is a long question so i get it if you can't answer all of it, but if you could at least help me get started i'd really appreciate it (sample.txt is the name of the file we have to download) (1) Prompt the user to enter the name of a file. This will be the file we use as input to our program. Determine if the file name inputted is valid. If it is, print a statement confirming this to the user. If the file is not valid, print an error to the user and ask for a new input (This should repeat for repeated invalid file names) Ex: Enter the name of a file: sample.txt Opening file: sample.txt Enter the name of a file: garbage.notafile The file "garbage.notafile" is not valid! Enter the name of a file: ... Hint: functions in the os.path module may help determine if the file is valid (2) The file can now be read by our program, implement a function read_file(file_name) that takes in the string containing the file name as a parameter and returns a string with the…arrow_forwardFile Display Assume that a file containing a series of integers is named numbers.dat and exists on the computer’s disk.
