This part will open an ordens file that has been entered on your website and built. It contains information about ordered systems. The serial numbers for the components have already been assigned. The serial number for the complete system has not been assigned and will be generated when you read the orders file.

Create a Class called "Order" to hold a complete order when read.

a$.$ Attributes: Order number, custName

b$.$ syslnfo : type System. Has the information for computer system of this order,

Create a Class called OrderMgr. It will hold the Orders and have various print and support methods.

a$.$ Attributes: vector of type Order named orders to hold the orders as they are read.

b$.$ Methods: printlnvoices $0,$ printSummary $0$

Open Orders.bxt file for input.

Read in each order, allocate and populate a new computer object for each system.

Close the order file and create an output file Invoice.txt$.$

Have the orderMgr print the invoices to the invoice file. The invoice file has the following format:
