- 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.arrow_forwardAlgorithm Workbench 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.arrow_forwardFile Display ProgramWrite a program that asks the user for the name of a file. The program should display thecontents of the file on the screen. If the file’s contents won’t fit on a single screen, the program should display 24 lines of output at a time, and then pause. Each time the programpauses, it should wait for the user to strike a key before the next 24 lines are displayed.arrow_forward

Each random number should be in the range of 1 through 500. The application should let the user specify how many random numbers the file will hold. * Please use the Python program.arrow_forwardObjective: Practice file handling Lab Description: Write a python script (with comments) that computes the average score for an unknown number of students in a file. Specifically, your script should: Ask for a filename name (that has scores in it) Open the scores file Verify the scores file opened correctly Read the student's name and their four scores Display the student's name, all of their scores and their average to the screen Writes the students name and the scores' average to a file name "averages.csv" Close both files For example, the following are examples of correct execution (with the text in bold being the input from the user): Input file project4-inputA.txt: Output to the screen: Output file "averages.csv" Мary 76 89 82 100 Joey Please enter the scores filename: project4-inputA.txt # Student name, grade average You entered project4-inputA.txt Opened scores file project4-inputA.txt Mary scores: 76.0 89.0 82.0 100.0 average: 86.75 Joey scores: 91.0 81.0 83.0 95.0 average:…arrow_forward

The program should display the contents of the file on the screen. Each line of screen output should be preceded with a line number, followed by a colon. The line numbering should start at 1. Here is an example: George Rolland 127 Academy Street Brasstown, NC 28706 If the file's contents won't fit on a single screen, the program should display 24 lines of output at a time, and then pause. Each time the program pauses, it should wait for the user to strike a key before the next 24 lines are displayed. Note: Save text below as the file to use and name it forChap12.txt file for this assignment. The line numbers should NOT be reset for each screen.
