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?
Step by step
Solved in 2 steps
- You are given a filename. Read the names in the file and output only the initials. For example, if the filename is "data.txt", and the file content in "data.txt" is Dumond, Kristin Larson, Lois the output should be: KD LLUse loop to solve this python program and use Error handling:IOError (File not found)Write a program that writes 100 integers created randomly into a file. Integers are separatedby a space in the file. Read the data back from the file and display the sorted data. Yourprogram should prompt the user to enter a file- name. If the file already exists, do not overrideit.
- 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?you should create a program that takes a file name as an argument, and prints the hex dump of it. help to solve by javaFile names: color_square.py, chessboard.py, test_squares.py Positions on a chess board are identified by a letter and a number. The letter identifies the column; the number identifies the row. See the image below. You will provide the functions that allow us to determine: if a chessboard square is either black or white, given its coordinates. If the row/column is valid or not for the standard chessboard For example, if we pass in “d” for the column and 4 for the row, your function that determines color should return the string: “BLACK”. If we pass in "k" for the column to your function that validates columns, that function should return the boolean False. Requirements: Your function for validating the column should be able to accept upper or lowercase strings as parameters. Your functions for validating the row should be able to accept integers or strings as parameters. Your function that determines black-or-white may assume that the input has been validated prior to us calling…
- <<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 fileYou develop a Python application for your school.You need to read and write data to a text file. If the file does not exist, it must be created. If the file has content, the content must be removed.Which code should you use? Group of answer choices C. open(“local_data”, “w+”) D. open(“local_data”, “w”) A. open(“local_data”, “r”) B. open(“local_data”, “r+”Answer All the questions. Make sure your answers are short and precise. You can use (Q1.txt or Ed) files to check your answers for Q1. 1. The phone numbers collected from questionnaire is a mess. Design a regular expression to filter out those numbers that are stored in the standard format "+00-0-0000-0000" from the file called "Q1.txt" and redirect the results to the "cleaned.txt". +61392144979 +61 3 9214 4778 +61-3-9214-4980 +66(2)51574430 +61-3-9285-7706 Note: Only +61-3-9214-4980 and +61-3-9285-7706 are the valid results.
- In C++ (don't copy paste the same answer that is already on this site, post unique code) Structures A menu-driven program gives the user the option to find statistics about different baseball players. The program reads from a file and stores the data for ten baseball players, including player’s team, name of player, number of homeruns, batting average, and runs batted in. (You can make up your data, or get it online ) Write a program that declares a struct to store the data for a player. Declare an array of 10 components to store the data for 10 baseball players. The program prints out a menu (in a loop, so this can be done again and again) giving the user a choice to: print out all users and statistics print out the statistics for a specific player print out all data for a specific team update the data for a particular player (change one of the statistics) DO ALL WORK IN FUNCTIONS. USE A FUNCTION TO READ THE DATA, A FUNCTION TO PRINT THE MENU, and FUNCTIONS FOR EACH OF THE MENU…Create a new file (in Dev C++) . In Lab 2, you created a menu for a simple calculator program. In Lab 6, you added some functionality based on the user selection. In Lab 7, you added some functionality for a main program loop and input validation. In this lab, you will create some general purpose functions to offload some of the tasks in main(). Write functions for: displaying "hello" message displaying menu displaying "goodbye" message displaying "invalid selection" message (for invalid menu selection) displaying "invalid input" message (for divide-by-zero input validation) Prototypes should be written for each function Function definitions can be in any order, after main() Call the functions as needed in main(), replacing the original code The program should: call function to display a "hello" message before presenting the menu call function to display the menu prompt user for selection accept either uppercase or lowercase for selection call function to display error message if…Please write the code in c
