Ok the first { is the problem... when I compile the code it says that main must return a integer....

#include <iostream>
#include <ctime>

using namespace std;

void main( void )
{  /* the problem is this bracket right here */
     int i, j;
     srand( (unsigned)time( NULL ) );
     /* Display 10 numbers */
     for ( i = 0; i < 10; i++)
     {
         j = rand();
         cout << j << endl;
         }
     
     system ( "PAUSE" );
     cin.get();
     return 0;
}

That's a fairly clear error message. Main is supposed to return an integer. Returning an integer when you've declared the return to be void is prolly not the slickest move you'll make today. The bracket has nada to do with it. Try "int main (...blah blah...)". Incidentally, some compilers will accept "void main (....", but that doesn't mean it's right. MSDN, bless their pea-pickin' li'l hearts, published a lot of sample code that did that, rightly or wrongly.

Thanks DaWei... I didn't realize that it was that simple sorry for posting a simple error...

Hey, nothing wrong with simple errors. That's the kind that give us the most gray hairs. The merits of "void main" are a relatively frequent topic of discussion.
