Hello all!

I am having trouble writing this code where I am supposed to take integers and output them as strings. When i try a number like 67 it outputs it correctly like sixty seven. However, when i try 467 it only outputs four hundred sixty. Suggestions appreciated!

```
#include <iostream>
#include <string>
using namespace std;
string n2w1to999(int digit);
string n2w1to9(int digit);
int main ()
{
int number;
int newnumber;
string words;
cout << "Input:" ;
cin >> number ;
cout << "Output:";
if (number == 0)
{
words = "zero" ;
cout << words << endl ;
}
if (number > 999999999)
{
words = "Error" ;
cout << words << endl;
}
else
{
if (number > 999999 && number <= 999999999 )
{
newnumber = number/1000000 ;
words = n2w1to999(newnumber);
cout << words << "million " ;
number = number - newnumber*1000000 ;
}
if (number > 999 && number <= 999999 )
{
newnumber = number/1000 ;
words = n2w1to999(newnumber);
cout << words << "thousand " ;
number = number - newnumber*1000 ;
}
if (number > 9 && number <= 999)
{
words = n2w1to999( number);
cout << words << endl ;
}
if (number > 0 && number <= 9)
{
words = n2w1to9(number) ;
cout << words << endl;
}
}
}
string n2w1to9(int digit)
