A hotel salesperson enters sales in a text file. 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 exist or the format is incorrect.

Write a program that reads a text file as described in Exercise P7.16, and that writes a separate file for each service category, containing the entries for that category. Name the output files Dinner.txt, Conference.txt, and so on.
