// -------------------------------------------------------------------------------
// 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.
byronflds (119)
yes I just checked the repository and shoppers.dat is there
maeriden (872)
Is shoppers.dat in the same directory of your executable? How do you run it?
byronflds (119)
yes . im in unix so i did

: g++ coupons_c.cpp -o coupons_c.run

then ./coupons_c.run
maeriden (872)
Well, I'm using a MinGW shell but I can compile and execute just fine using that procedure. I'm lost
