· Exercise # 4A 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 exit or the format of the record is incorrect. No need to display anything else in this regard. Note that you can assume that the dates are entered correctly (no need to validate them).
