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.

Each line contains the following, separated by semicolons: • The name of the client, the service sold (such as Dinner, Conference, Lodging, and so on), • The amount of the sale, and the date of that event. • Write a program that reads such a file and displays the total amount for each service category. Display an error if the file does not exit or the format of the record is incorrect. No need to display anything else in this regard.
