Answer to Question #4522 in C++ for sya

Question

Create a structure named Purchase. Each Purchase contains an invoice number, amount of sale, and amount of sales tax. Create a main() function that declares a Purchase variable and prompts the user for purchase details. When you prompt for an invoice number, do not let the user proceed until a number between 1000 and 8000 has been entered. When you prompt for a sales amount, do not proceed until the user has entered non-negative value. Compute the sales tax as 5 percent of the purchase price. After a valid Purchase variable has been created, display the variable’s invoice number, sale amount and sales tax.
