Printing a specific number of digits

Hi all:

Is it possible for an int to print a specific number of digits every time?

For example:

int x = 1;
cout <<x <<endl; //should print 001

x = 999;
cout <<x <<endl; //should print 999

Thanks.

You could just add it:

Code:

---

int x = 9;
cout << "00" << x << endl;//009

---

To work with all kinds of numbers:

Code:

---

if ( x < 10 )
{

    cout << "00";
}

else if ( x < 100 )
{

    cout << "0";
}

cout << x << endl;

---

Ah, that works. Good thinking.

I'm going to use that for now. However, I do recall a more elegant way of doing it (by formatting the number before printing, perhaps?). Just for my personal knowledge, does anyone know how this can be done?

Thanks.

Code:

---

#include <iostream>
#include <iomanip>
using namespace std;

int main()
{
  for ( int i = 1; i < 1000; i *= 10 )
  {
      cout << setfill('0') << setw(3) << i << '\n';
  }
}

/* my output
001
010
100
*/

Awesome. Thanks bud.
