ok... hi all :) ive bean kindof relient on Kilowatt. "sorry kilowatt" now my question... i want to random a number betwean 1-10. i looked up rand()... automatically i thought that you could just put the number that you want to be randomized in the ().... like for example rand(10)... that didnt work. there is srand also... why wont the rand(10) work... and, how do i work rand()? Thanks all! ~SilverShalkin :rose:

#include "stdafx.h"
#include <stdlib.h>
#include <time.h>int _tmain(int argc, _TCHAR* argv[])
{
srand((unsigned)time(NULL));
for(int i=0;i<10;i++)
printf("%d\n",rand()%10);
return 0;
