I am a first year compsci university student and i'm havin trouble with the
following c++ question.
anyway sort of help would be much appreciated
Modify the grocery store program so that it will calculate the profit and keep track of inventory levels for a variable number of grocery items, up to a maximum of 20. For each item the user inputs an item number, a 3 digit integer, the number if items initially on hand, and the number of items sold. Cost and selling prices are stored constant values. Ma and Pa classify items according to customer demand which is calculated as the percentage of items sold per the initial number of items on hand.
demand = items sold/initial on hand x 100
Their classification system is as follows:
0 <= demand < 20 = Poor
20 <= demand < 50 = Low
50 <= demand < 70 = Good
demand >= 70 = Excellent
For each item the program will output the item number, the profit made from sales of that item, the number of that type of item remaining in stock and classify the demand for the item.
After processing details for each item, the program will print out the total profit from all sales, and the average profit per item. Your program should check for valid input.
NOTE: Your program does not need to use sorting or searching!
