File for each service category Dinner.txt John Doe; Dinner; 45.69;04/19/2020 Jane Smith;Dinner;50.00;04/19/2021 Conference.txt Sean Kim; Conference; 1000.00; 05/03/2021 Mike Jones;Conference;750.00;05/01/2021 Note: Don't hardcode service categories i.e. the program should support dynamic number of categories.
