silly question

[jkw119]

I have kind of a silly question...

I am trying to display an Integer as 0001, istead of 1. And when I increment it, I need it to be 0002, 0003, ....0124, etc. Does anyone know how I can do so?

Thanks,

Jeff

Using C++:

#include <iostream>
#include <iomanip>

int main()
{
    int i = 1;
    std::cout << std::setw(4) << std::setfill('0') << i; // prints "0001"
    return 0;
}

Using C:

#include <stdio.h>

int main()
{
    int i = 1;
    printf("%04i",i); // 0001
    return 0;
}
