leading zero on single digit int

Is there a way to include a leading zero on a single digit int using cout without using if statements?

edit: nevermind, if statements are sufficiently easy

In case you still wanted to know, the printf statement can do what you want. You'd have to specify the precision ( I believe it is .#, that is, a period followed by a number). In the case of integers it will force the output to have a specific minimum number of digits and print leading zeros if necessary. I found that info on the following page:

Code:

---

#include <iostream>
#include <iomanip>

using namespace std;

int main(void)
{
  int a = 3;

  cout << setw(2) << setfill('0') << a << endl;
  return 0;
}
