Inventory Application Program
This project involves designing and creating a C++ program which will utilize the InventoryItem class, which is described in Section 13.10 (pages 771-775) and Section 13.12 (pages 777-780) of the Gaddis textbook. (The InventoryItem.h source code for this class is provided on Moodle.)
The program should create an array of 100 InventoryItem objects and support the following interactive commands:
a Add parts: increase the units value for an existing inventory
h print Help
i Input inventory data from a
p Print inventory list.
n create a New inventory
o Output inventory data to a
q quit (end the program).
r Remove parts: reduce the units value for an existing inventory
Data File Format
The “input” / “output” commands read / write data which is in a “pipe-delimited” text file. The format of each line of text, in the data file, is described below:
|
File Format |
|
inventory item number | description | cost | units |
|
Explanation of Data Fields |
|
|
Field name |
Explanation |
|
inventory item number |
For the output file, this number can be the same as the array index. For the input file, the contents of this field will be ignored, because the input data will be appended to the end of the “populated” portion of the InventoryItem array. |
|
description |
Description of the inventory item |
|
cost |
Cost per unit for the inventory item |
|
units |
Number of units present for the inventory item (must be greater than or equal to zero and less than or equal to 30). |
Sample Test Data
Four sample input files are provided: electrical.txt, fasteners.txt, miscellaneous.txt and plumbing.txt. The data files which your program creates must obey the same file format as these sample files.The program should work correctly with these files, as well as general files of similar format.
