changing the date into a number

ok so i read the function help on this site and found out how to get the date now all i want is to be able to compare the date to another varible so i would like to be able to change the date into a number...

read each part of the date into an int
so you have

d=21
m=01
y=2001

then cast them to strings and join them up tom become one string
dmy [8] ="21012001"

If you're comparing dates against other dates, it is probably easier to reverse them -

yyyymmdd

20020121

That way you can tell with one comparison if one date is before or after another.

ok so now how do i change hold_time into this format yyyymmdd

Code:

---

#include <time.h>
#include <iostream.h>

int main()
{
        time_t hold_time;
        hold_time=time(NULL);
        cout<<hold_time;
        cout<<time;
        return 0;
}
