how to display 1 as 01?

[Erich Pul]

hi!

i have an integer with a value of, say, 2 and want it to look like 02
or, for a date class, 0002 (like e.g. 02-02-2006)

please help!

Hi ,

use
printf("%02d", num)
or
printf("%04d",num);

#include <ostream>
#include <iomanip>

int a = 2;
int b = 10;

std::cout << std::setw(2) << std::setfill('0') << a;
std::cout << std::setw(2) << std::setfill('0') << b;
