Solution for Chapter 2 Exercise 5a
a. Draw the hierarchy chart and then plan the logic for a program for the sales manager of
The Couch Potato Furniture Company. The manager needs a program to determine the profit
on any item sold. Input includes the wholesale price and retail price for an item. The output is
the item’s profit, which is the retail price minus the wholesale price. Use three modules. The
main program declares global variables and calls housekeeping, detail, and end-of-job
modules. The housekeeping module prompts for and accepts a wholesale price. The detail
module prompts for and accepts the retail price, computes the profit, and displays the result.
The end-of-job module displays the message “Thanks for using this program”.
