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

srand( (unsigned)time( NULL ) );

for( i = 0; i < 10;i++ )
printf( " %6d\n", rand() );
