Given an initialised variable fileName, write a series of instructions that produces a file with the name indicated by fileName and a single line stating "This Is File:" followed by the file's name. Verify that the data written to the file has been purged from its buffer and that all system resources utilised by these statements have been freed. (Don't worry about exceptions; presume they're handled elsewhere.)

- Write a set of instructions that, given an initialised variable fileName, creates a file with the name given by fileName and a single line that says "This Is File:" followed by the file's name. Check that the data saved to the file has been removed from the buffer and that all system resources used by these lines have been released. (Don't worry about cases; just assume they're taken care of somewhere else.)Given an initialised variable fileName, write a sequence of statements that creates a file with the name specified by fileName and a single line containing "This Is File: " followed by the file's name. Verify that the data written to the file has been purged from its buffer and that all system resources consumed by these statements have been released. (Do not worry about any potential exceptions here; assume that they are handled elsewhere.)Given an initialized variable fileName, write a sequence of statements that create a file whose name is given by the variable and whose content is a single line consisting of "This Is File: " followed by the name of the file. Make sure that the data written to the file has been flushed from its buffer and that any system resources used during the course of running these statements have been released. (Do not concern yourself with any possible exceptions here-- assume they are handled elsewhere.)
- You are given a String variable named file. It contains the name of a one-line file. Write a sequence of statements that make an exact copy of the file and give it the same name but with the string ".cpy" attached to the filename. Make sure that the data written to the file has been flushed from its buffer and that any system resources used during the course of running these statements have been released.(Do not concern yourself with any possible exceptions here-- assume they are handled elsewhere.)Consider the following code segment: done = False while not done : try : filename = input("Enter the file name: ") inFile = open (filename, "r") except IOError : print ("Error: File not found.") It is supposed to keep on prompting the user for file names until the user provides the name of a file that can be opened successfully. What line of code should be placed in the blank to achieve this goal? Select one: done = inFile done = True done = not inFile done = FalseAll I need is the main.cpp file Programming Specifications: Task: Two files have been provided (wordcounter.h and wordcount.cpp). You must open a text file, read in each word until end of file, add each word to the WordCount library and print the report. Your program must request a filename of a text file that contains words to count. You must check to see if it is a valid file and issue an error message if not and request a new file name until a valid one is entered. You must have at least one function that either passes in a parameter and at least one function that returns a value. You can have a single routine that does both. You must declare the class object properly, use AddWord() to add the word to the catalog and use PrintSummary() to produce the output. Design Considerations: The file will contain only words (no punctuation or special characters) less than or equal to 13 letters. There will be no limit to the number of words. You must open the file and read each…
- Write a sequence of statements to create a file with fileName's name and a line saying "This Is File:" followed by the file's name. Check the file's buffer and system resources consumed by these statements. (Ignore exceptions.)Instructions Add a command to this chapter’s case study program that allows the user to view the contents of a file in the current working directory. When the command is selected, the program should display a list of filenames and a prompt for the name of the file to be viewed. Be sure to include error recovery in the program. If the user enters a filename that does not exist they should be prompted to enter a filename that does exist. An example of the program input and output is shown below: /root/sandbox 1 List the current directory 2 Move up 3 Move down 4 Number of files in the directory 5 Size of the directory in bytes 6 Search for a file name 7 View the contents of a file 8 Quit the program Enter a number: 7 Files in /root/sandbox: filesys.py example.txt Enter a file name from these names: example.txt THIS IS CONTENT OF AN EXAMPLE FILE. /root/sandbox 1 List the current directory 2 Move up 3 Move down 4 Number of files in the directory 5 Size of the directory in bytes 6…Write a series of statements that produces a file with the name supplied by fileName and a single line stating "This Is File:" followed by the file's name. Check that the file's buffer is empty and that all system resources used by these statements have been freed. (Assume any exceptions are handled elsewhere.)
- I need help with this C programming assignment: The program prompts the user to type in a text file name (without the directory structure), then it repeatedly reads integer values from the file until the end of the file is reached. Every time an integer is read from the file, the program prints it to the screen for debugging purposes. Once the file is fully read, the program closes it, prints the number of values read to the screen, then opens a new file called "output.txt." The program then prints three lines to this file; the sum, average, and product of the values read. If the user enters an invalid file name or the file cannot be opened for any reason, the program must print an error message. For instance, suppose the contents of your input file "input.txt" are as follows: 1 2 3 The run of the program on console output would look like this: Enter file name: input.txt Values in input: 1 2 3 Read 3 value(s) from file …then, the contents of your output file (named "output.txt") would…Explain in your own words: a.) Why do we need file in programming? b.) What is a potential error that can occur when a file is opened for reading?In c++ what is a file? Why is it necessary to "open" and "close" a file? What happens when we do that?
