    Default Math calculations

    Hi!

    A friend of mine is trying to write a simulation of an ATM and can't seem to get it right.

    He want's it like so:
    If a user wants $100 and there are no $50 notes left, the machine gives them 5 $20 notes. Or if there are only 2 $50 note left in the machine and you want $150, it should dispence 2 x $50's, 2 $20's and 1 $10.
    Is there a way to account for this scenario?

    I dabbled in Java a few years ago but I tried to do this and have no idea.

    Does anyone know how to achieve this?

    Thanks in advance!

    Have you thought through the steps a program must take to do what you are asking?
    Can you list the steps you have so far and ask any questions about the problems you are having in getting the logic for the program.
    I dabbled in Java a few years ago but I tried to do this and have no idea.
    So far this doesn't have anything to do with java. Its the design of a program to do a task.
    Once you have a design, then think about how to write it in a programming language.
    If you don't understand my answer, don't ignore it, ask a question.
