Files Class Activity Write a program to write your first name (hard coded) to the screen and possibly to a file whose name is passed into the program from the command line. It can be written in upper or lower case or mixed case as the default. Usage: writer [-f filename] If the -f option is included with a filename, then create a file with that name or overwrite a previously existing file and write your name in on the first line. If the -f option is not included, then only write your name to the screen followed by a newline. Use a copy of the original getopt to parse the command line. Be sure to test whether a file open succeeds or not and close any file you open when done.
