Doheny's Pool Supply needs a program that will needs a program that will prepare invoices for chemicals ordered by its customers. The user will input the customerA's name and the chemicals ordered (item numbers and quantities). Then the program will locate the item numbers in a data file to determine the chemical names and prices and print an invoice. This invoice should contain the customerA's name and, for each chemical ordered, the quantity, item number, chemical name, chemical price, and total price. The chemicals ordered should be listed on the invoice in ascending item number order and the total amount due should be given at the bottom. You will assume that the items numbers, names, and prices (the price list) are contained in a sequential file called "pricelist be, with records of the form as follows chemNumber (Integer), chemName (String). chemPrice (Float)
