Question

You are to write a program to produce an inventory report for a local company. Your input will be item name, item number, quantity, price per item, safe stock value. The following shows which columns the input will be in:

item name             item number         quantity                  price                      safe stock

20 chars                 5 char                     3 char                      6 chars                 3 chars

Output will be as follows:

item number         item name    quantity   price     price*quantity   %ofStock    flag

You will place a symbol in the flag field if the inventory quantity is less than the safe stock value.

This tells the company that they are getting too low on this item and need to build up the inventory stock.

Output:

1.        Print the report in sorted ordered, sorted on item number.

                  For each item, indicate the total value of the stock and the percentage of this item to the total     stock’s value.

2.       Indicate the percentage of total inventory value to the total value of the highest single item in inventory. Print the item and its information. (Print this at the end of the table. )

3.     Indicate the percentage of total inventory value to the total value of the three least valued items combined. Print the three items and their information, again at the end of the table. ( I just need to see how much of the companies monies are tied up some of the lesser inventory.)

Restrictions:

You must use a link list for the inventory (no array). C++ Language
