using % to get 2 digit year

Hi-

I'm trying to use the mod operator to convert a 4 digit year to a 2 digit
one. Here is what I'm doing:

WORD shortYear = 2004%2000;

the result is always 4 instead of the desired 04
I don't even know where to begin with this one. I googled pretty hard, but
didn't find anything informative.

Thanks for any help,
Steve

You probably want

WORD shortYear = longYear%100;

1990%2000 == 1990, but 1990%100 == 90

You got a number, not a string. It is meaningless to say that a number
has or does not have leading zeros. When you convert it to a string or
format it for printing, that's when you can add leading zeros.

4 is the same thing as 04. (It's also the same as 004, 0004, etc.)

If you want to output the value of shortYear with one leading zero (i.e. 4
becomes 04), you'll have to look up how to do that with whatever output
function you're using.

For example:

WORD shortYear = 2004 % 2000;
printf("shortYear = %d = %02d\n", shortYear, shortYear);

prints:

shortYear = 4 = 04

of course. I was trying to use SetDlgItemInt(), a quick format to string
and I am good to go using AddString()

Thanks and sorry for the pretty dumb question.
