    Unhappy simple shopping cart

    Dear Guys,
    im very beginner in programming and I want to make a simple shopping cart as follows and a cant figure it out :

    this program should allow the user to order from small catalogue then calculate the final bill including tax at 20 %. sample program should look like this:

    our catalogue [ product code in brackets]:
    1-water [k1234] 3$
    2-honey [k123] 2$
    3-meat [p123] 1$
    Buy something!

    Enter order number (o to stop): k1234
    Enter Quantity : 5
    Enter order number (o to stop): 5667
    Sorry I don't understand use product code only.
    Enter order number (o to stop): 0
    your order
    5 water @ 3$ = 15 $
    subtotal : 15.00 $ Tax @ 20 % : ..............
