I have to design and develop a program to be used to assist a grocery in maintaining their inventory.

I have to design and develop a program to be used to assist a grocery in maintaining their inventory. I have to declare and initialize four array data structure to store product code, description, unit price and amount in stock for food items. Before I do this, I have to do IPO charts for all items in inventory, out of stock items,  total value of stock items, most expensive item in inventory, and total cost of order, then do a flow chart. Can anyone help me with this?
