    Default Policy Class

    Can someone help me figure out how to print the number of smoker and number of nonsmoker?

    What does the program output now? Please copy contents of console and paste it here so we can see what it is doing.
    Add some comments to describe what is wrong and show what is desired.

    Please edit your post and wrap your code with code tags:

    [code]
    **YOUR CODE GOES HERE**
    [/code]

    to get highlighting and preserve formatting.
    If you don't understand my answer, don't ignore it, ask a question.

    Default Re: Policy Class

    Where are the comments in the output describing what is wrong with it
    and showing what the output should be?

    For example:
    Item 1: abc
    Results are 1234 <<<<<<< This is wrong, results should be 3456
    More output here


    The posted code does not compile without many errors.
    Please fix the compiler errors and post the correct code that will compile and execute.
    If you don't understand my answer, don't ignore it, ask a question.
