After I figured out how to do random and eliminated the access violation
when trying to do time functions, here's a little more random version
for getting different numbers for different runs.


program listing
---------------
#include <stdio.h>
#include <stdlib.h>
#include <winbase.h>
main()
{
int myvalue;

static SYSTEMTIME SystemTime;

GetSystemTime(&SystemTime);

srand(SystemTime.wMilliseconds); /* use millisecond timer as seed for
srand *

myvalue = rand();

srand(myvalue); /* more randomness */

myvalue = ((float)rand()/RAND_MAX)*100.0; /* scale from 0 to 100 */

printf("%d\n",myvalue);
myvalue = ((float)rand()/RAND_MAX)*100.0; /* scale from 0 to 100 */

printf("%d\n",myvalue);
}

Seems to work fine for me.
