The first line becomes last, the second line becomes the one before the last one and so on. Note: your program should have two arguments, the input file name and the output file name.

- Write a C program, called reverse, using standard I/O functions, to take a file as inputthen copies it to another file in reverse order.

- 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.)Explain in your own words: a.) What is a file’s read position? Where is the read position when a file is first opened for reading? b.) Why should a program close a file when it’s finished using it?You have been tasked to write a C++ program that will go through the first step of encrypting an input file and writing the encrypted contents to an output file.For each letter read in from the input file, add 3 letters to the value of the input letter. If the input letter is an A then the encrypted letter would be a D. If the input letter from the input file is an X then the encrypted letter would be an A. All spaces, digits, punctuation, and special characters do not need to be encrypted at this level. Simply write the space, punctuation, or special character to the output file as is. If a letter is uppercase in the input file, it should remain as an uppercase character in the output file. If a letter is lowercase in the input file, it should remain as a lowercase character in the output file.Since this program runs each month, the input file will be of various lengths; therefore, the program will read until end of file.The input file is found in the current directory and is…

If the number of arguments in the command line are more than or less than two, then the program should terminate with an appropriate error message. Otherwise, it should open the first file and copy its contents into the second file, in effect overwriting its contents, if any.
