i have an important homework for my computer class...
we need to create a cash register... much like with the mcdonalds... where when the cashier would input the order... the price appears and then when the order is finished... it would sum up all the prices and would also give the amount of change...
Cash Register is a smaller version of the machines used by the cashiers in various food chains. In this
application, the user (the cashier) must be able to select the item/s ordered and indicate the quantity of each
item ordered. After each entry, the application has to be able to generate/update the receipt. When all
orders have been taken, the cashier will have to enter the amount of cash given. The application will
compute for taxes and change, and update and display the complete receipt.
here's a sample of a print screen...

here's my code... im stuck after this... was stucked in the addition of the prices of the ordered items... i dont know what to do next XD
