When you say "auto-generate" I think of random numbers, but it looks like you're talking about incrementing numbers. Can you be a little more specific on exactly what you want?

Take a look at srand and rand.

Absolutely, I don't think that I understand what you said all.

Due to my understand It's my answer:

You can use a large number begin with 1
ex: id = 1000;
And after that you can general other number so that it's less than id
ex: id2 = rand()%id;
And finally you can sum both of them
ex: result = id + id2;

thx i know ald

/* RAND.C: This program seeds the random-number generator
* with the GetTickCount, then displays 10 random integers.
 */

#include <stdlib.h>
#include <stdio.h>
#include <winbase.h>

void main( void )
{
   int i;
   /* Seed the random-number generator with GetTickCount so that
      the numbers will be different every time we run.
       */
   srand(
       GetTickCount() 
         );
   /* Display 10 numbers. */
   for(
         i = 0;   i < 10;i++ 
        )
   printf(
         "%6d\n", rand() 
        );
   }

I have no idea what language you're speaking.

[skypin]

you can also to customize generate number :

int 
GetRandomNumber(int nLowNumber, int nHighNumber)
{
  const int IMax = dwLowNumber;
  const int IMin = dwHighNumber;
  
return (IMin + rand() % (IMax - IMin));
}

// Example Usage : generate number between ( 12 ... 102)
// int randnum = GetRandomNumber ( 12, 102 ) ;
