Hey guys, this is my first time using object oriented programming and I'm having a little bit of trouble. I'm trying to create a "Store" class that feeds off my "inventory" class which I have already created. I have to make four member functions: 1) add an inventory item 2) search for an inventory item 3) delete and inventory item 4) show quantity, cost of each inventory item 5) modify an inventory item. I have started it but am stuck on how to modify the item. I have attached all of the programs. The prog6.cpp is the driver for my inventory class.
