    need help with classes, stacks

    program isn't working....I have been working on it and reading. Am I even close?
    The program has two classes, one for the data, one for the stack. The program is supposed to get a number from the user and convert the number to binary, octal and hex. With binary push each remainder on the stack and then pop them off traversed. I am just trying to get it to work with binary right now

    sorry I don't have time to look at your stack implementation right now, but here is the problem with the namespace

    #include "number.h" //class
    #include <iostream> //headers
    using namespace::std;

    should be,

    #include <iostream> //headers
    using namespace std;
    #include "number.h" //class

    I believe that should fix it.

    some entropy with that sink? entropysink.com
