Wood-screw Inventory File version

The wood-screw inventory: revisited
Goals

To write a program that uses file handling functions.

Problem description

Take your wood-screw inventory program and modify it to work with files. The internals can remain exactly the same, but input must come from a file, and output must also go to a file. The names of these files are to be specified on the command line when you run the program. e.g.

% a.out inputfile outputfile

Deliverables:

your source code, suitably commented and with good layout

the output produced by the program with the following input sequence (note the use of a special value as a sentinel -- see page 69 of the textbook). The first number is the size of screw, and the second is the change in the inventory amount.

6 1000
8 1500
10 1200

12 100

Notes and hints

make sure you check the command line variables for the correct number of arguments

make sure you check for correct opening of the input file

make sure to close the input file when you are done with it

use fscanf for the input file

use fprintf for the output file
