These are the instructions for this particular portion of this program I am suppose to follow, already 1 day late in submitting it to my instructor.
Modify the Inventory Program to use a GUI. The GUI should display all of the items in the inventory and include the item number, the name of the product, the number of units in stock, the price of each unit, and the value of the inventory of that product. In addition, the GUI should display the value of the entire inventory, the additional attribute, and the restocking fee. All dollar values should be displayed as currency (i.e. $D,DDD.CC). There should not be any output in the DOS console.
