Design a program and write program that will read a file of sales records and produce a sales report. Each record in the file contains a customer's number and name, a sales amount and a tax code. The tax code is to be applied to the sales amount to determine the sales tax due for that sale, as follows:

Question

Tax code
Sales tax

0
Tax exempt

1
3%

2

The report is to print a heading 'SALES REPORT', and detail lines listing the customer number, name, sales amount, sales tax and the total amount owing.
