Question

This is a substantial project and could be a candidate for your e-portfolio. For week 4’s assessment we will be creating a "real-world" solution that could be used by a company for inventory control.

You can either have 4 separate projects (each with its own main(), or you can have one project and have the 4 parts done in that main() function.

The requirements of this project are the development of a program that includes an inventory class with data members for stock number, quantity, price, also overloaded data entry and output operators. The data entry operator function should throw an error message if:

An error message, if the stock number is negative or higher than 999

An error message if the quantity is less than 0

An error message if the price is over $100.00

Your programs need to perform the following tasks:

1) Write a main() function that instantiates an array of five Inventory objects, and accepts data for each. Display an appropriate error message for each exception situation. When an exception is detected, replace all data fields with zeroes. At the end of the program, display data fields for all five objects. You should have ONE C++ source file for the main(), and separate Inventory.h and Inventory.cpp files for the Inventory class.

2) Write a main() function that instantiates an array of five Inventory objects and accepts data for each. If an exception is thrown because of an invalid stock number, force the user to reenter the stock number for the Inventory object. If the quantity is invalid, do nothing. If the price is in error, then set the price to 99.99. (Add a setPrice() function to the Inventory class to accomplish this.) At the end of the program, display data fields for all five objects.

3) Write a main() function that instantiates an array of five Inventory objects and accepts data for each. If an exception is thrown because of an invalid stock number, force the stock number to 999; otherwise, do nothing. (Add any needed functions to the Inventory class.) At the end of the program, display data fields for all five objects. .

4) Write a main() function that instantiates an array of five Inventory objects and accepts data for each. If any exception is thrown, stop accepting data. Display as many objects as were entered correctly.

Because this is a portfolio quality project, please fully comment all of your code, including a descriptive header for each code file, and provide design documentation in the form or a MS-Word document or a PowerPoint presentation.
