// COP 3014C Fundamentals of Programming
// Assignment ID: PROG6a
// Due Date: 10/20/12 at 11 pm
// File name: coupons_c.cpp
//
// Author: bfields Byron Fields
//
// Purpose: You are shopping at your favorite store. You select one item
// of merchandise marked at its regular price. At the checkout,
// you are asked whether you have a coupon. If you do not, you
// will be charged the regular price. If you have a coupon, the
// cashier will determine whether it is a cash-off coupon, or
// a percent-off coupon. A cash-off coupon will reduce the regular
// price by a fixed cash amount; a percent-off coupon will reduce
// the price by a percentage of the regular price.
//
// Author: bfields Byron Fields
//
// NOTE: This is the FIRST STEP in the evolution of this program.
// ONE SHOPPER / keyboard INPUT / console OUTPUT

Make sure you actually have a 'shoppers.dat' file in the directory your working in.
Oct 20, 2012 at 10:03pm
yes I just checked the repository and shoppers.dat is there
Oct 20, 2012 at 10:32pm
Is shoppers.dat in the same directory of your executable? How do you run it?
Oct 20, 2012 at 10:51pm
yes . im in unix so i did
: g++ coupons_c.cpp -o coupons_c.run
then ./coupons_c.run
