* 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.
