    $end = 20;
    
    //generating 10 number
    print("random integers between $start and $end...\n");
    for($i=1; $i<=10; $i++)
    {
        print(random_int($start, $end)." ");
    }
    print("\n");
    
    $start = -100;
    $end = 0;    

    //generating 10 number
    print("random integers between $start and $end...\n");
    for($i=1; $i<=10; $i++)
    {
