- Which of the following opens the employ.txt file and allows the computer to write new data to the end of the files existing data? a. outFile = I0.File.AddText("employ.txt") b. outFile = I0.File.AppendText("employ.txt") c. outFile = I0.File.InsertText("employ.txt") d. outFile = I0.File.WriteText("employ.txt")Create a program named FileComparison that compares two files. First, use a text editor such as Notepad to save your favorite movie quote. Next, copy the file contents, and paste them into a word-processing program such as Word. Then, write the file-comparison application that displays the sizes of the two files as well as the ratio of their sizes to each other. To discover a files size, you can create a System. 10. Filelnfo object using statements such as the following, where FILE_NAME is a string that contains the name of the file, and size has been declared as an integer: FileInfo fileInfo = new FileInfo(FILE_NAME); size = fileInfo.Length;A student wants to write into a file called myfile, without deleting its existing content.

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 a message (void) display menu and return user selection (int) prompt user for a number and return the number (int) adding (void) subtracting (void) multiplying (void) dividing (void) checking if number is 0 (bool) Prototypes must be written for each function. Definitions for each function may be in any order, after main(). Call functions as needed. Remember that functions can call other functions. If you see the same code repeating in different places, there is a good chance that a function could be used to simplify things. By now, you've gone…
- Write a script named copyFile.py. This script should prompt the user for the names of two text files. The contents of the first file should be input and written to the second file. An example of the program input is shown below: Enter the input file name: copyFrom.txt Enter the output file name: copyTo.txt Output: After running the program, a file named copyTo.txt will be outputted that contains the text from the copyFrom.txt file.C++ Add a search command that asks the user for a string and finds the first line that contains that string. The search starts at the first line currently displayed and stops at the end of the file. If the string is found, the line that contains it is displayed at the top. In case the user enters a string X that does not occur in the file, the program should print the error message: ERROR: string "X" was not found. Attached is the first lines of the .txt filePython Question: Which statement correctly opens an existing file if you want to add lines to it?
