Stock Stack I

Widget Inventory Stock Stack - Static Implementation

FOR THIS ASSIGNMENT, WORK WITH THE STACK INSIDE AN ARRAY. (Stock Stack 2.0 will use a linked implementation.)

The Widget Store receives shipments of widgets at various costs. The store's policy is to charge a 20% markup and to sell widgets received later before widgets that were received earlier. This is a LIFO (last-in-first-out) policy.

Write a program that keeps track of the widgets in inventory using a stack. It will read input records of two types. Sales records and receipt records. A sales record represents a sale of a quantity of widgets and consists of the following fields: an 's', date of sale, time of day (a.m. or p.m.), and quantity. A receipt record represents a receipt of a quantity of widgets at a particular cost, and consists of: an 'r', date, time of day (a.m. or p.m.), quantity, and cost per item.

When a receipt record is read, print a message, e.g.:

After a sales record is read, print a message stating the number sold and the price for each widget. For example, if 200 widgets wre sold and there were 50 widgets from a shipment with a cost of $1.25, 100 at $1.10, and 50 at $1.00, the following would print (remember the 20% markup):
