Problems calling this function

Ive been trying to learn C++ for over two weeks now hoping to get into win32 api's soon but simple ........ is stumping me. I know all about data types and basic stuff but I just dont seem to get it? idk my code looks alright i though I didnt organize it here thats not what im worryin about I was wondering is this the best way to write this function?

Code:

---

// xwxw.cpp : Defines the entry point for the console application.
//

#include "stdafx.h"
#include <iostream>
void getnumber();

using namespace std;
int number;

int main()
{

        cout<<"Give me the number:";
        cin>> number;
getnumber();
        cin.get();
cin.ignore();


}

void getnumber()
{

        int x = 5;
int b = number;
        while (x < b) {
                cout<< x<<endl;
                x++;
        }
        cin.get();
        cin.ignore();
}

---

I would write it like this...

Code:

---

#include <iostream>

using namespace std;

void GetNumber(int number);

int main(){
   
    int number;
    cout <<"Type a number: ";
    cin >> number;
    GetNumber(number);
   
    return 0;
}
void GetNumber(int number){
              for(int x=5;x<number;x++){
                                    cout << x << endl;
                                    }
}

Using a for loop and not declaring global variables...

is that what you were looking for? :s...
