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:op' : looks like a function definition, but there is no formal parameter list; skipping apparent body
'{' : missing function header (old-style formal list?)
'bool stack:ush(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 stack::push(int rem)
{
	bool success;
	int n;
	number* nptr;
	
	if (n == 0)
	{
		success = false;
	}
	else
	{
		nptr = 0;
		nptr->remainder = top;
		top = nptr;
		count++;
		success = true;
	}
	return success;
}

program.cpp

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

void binary(int);

stack intstack;

int main()
{
	int numb;

	binary (numb);

	
}

void binary (int numb)
{
int n;
int nu;				

n = nu % 2;			
	
//push n on stack			


if (nu == 0)			
{
	return ;
}
else 
{
	return binary(nu / 2);	 
}
}

>>syntax error : missing ';' before 'namespace'

Code:

using namespace::std;  should be
using namespace std;

>>stack:pop' : looks like a function definition, but there is no formal parameter list; skipping apparent body
'{' : missing function header (old-style formal list?)

Code:

//bool stack:pop{}
bool stack::pop()
{
    number* dltptr
   .....

>>bool stack:push(int)' : overloaded member function not found in 'stack'

Code:

// number.h
bool push();

//number.cpp
bool stack::push(int rem)
{
...
unmatching parameter

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?
