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



syntax error : missing ';' before 'namespace'
syntax error : missing ';' before 'namespace'
stack::pop' : looks like a function definition, but there is no formal parameter list; skipping apparent body
'{' : missing function header (old-style formal list?)
'bool stack::push(int)' : overloaded member function not found in 'stack'

Code:

//number.h

#pragma once

class number
{
public:
        int remainder;
        number* data;

        number* next;

        number(void);
        ~number(void);
       

};

class stack
{
private:
        int count;
        stack* top;
       
public:
        stack() {count = 0; next = NULL;}
        ~stack();
        int is_empty();
        void getnum(int);
        bool pop();
        bool push();
}

//number.cpp
#include "number.h"
#include <iostream>

using namespace::std;


number::number()
{
        remainder = 0;
        next = NULL;
}

number::~number()

}

stack::stack()
{
        count = 0;
        top = NULL;

stack::~stack()

}

bool stack::pop{}
{
        number* dltptr;
        bool success;

        if (count == 0)
        {
                success = false;
        }
        else
        {
                dltptr = top;
                dataout = top->

       
        }
       
}

        bool success;
        int n;
        number* nptr;
       
        if (n == 0)
        {
                success = false;
        }
        else
        {
                nptr = 0;
                nptr->remainder = top;
                top = nptr;
                count++;
                success = true;
        }
        return success;

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.

Code:

---

class stack
{
private:
        int count;
        stack* top;
       
public:
        stack() {count = 0; next = NULL;}
        ~stack();
        int is_empty();
        void getnum(int);
        bool pop();
        bool push();
}; // Missing semicolon?
