Ok, so I have been tinkering a bit in CPP. I was wanting to do a cash register type system because its kinda simple yet a good challenge for me.
I am thinking about good ol iostream for echoing all of the choices, and switch statements or elseifs for taking user input and moving to the right next category... for example: 1-food, 2-products... when 2 is hit, switch or elseif takes to like products(); which throws a system cls and brings another menu.
it is all making sense to me except for the holding data. what I don't know how to do, is if the cash register picks a particular item in a categorie... hold that item to the subtotal, somehow cache it for a total list later, and then continue with punching in items... how would one go about doing this. The subtotal wouldn't be hard, i think just add whatever the items price is to the already set subtotal, but listing selected items seems harder while still punching them in. ???
