Design a program that will read a file of sales records and produce a sales report. Each record in the file contains a customer's ID, name, a sales amount, and a validated GST code.
The GST code is to be applied to the sales amount to determine the sales tax due for that sale, as shown below.
GST Code GST Rate 0 1 2 0% 5% 10% The report is to print a heading "SALES REPORT", and detail lines listing the customer's ID, name, sales amount, sales tax, and total amount due including sales tax.
