The numbers game and the fuel calculator were created simply for demonstration purposes.
The password generator and the IP Address Validator were created to solve real-life problems. The first was to demonstrate how the number of possible permutations for a password changes with
the complexity used to create it. The difference in strength between a simple case-insensitive alpha-only password of a few characters and a full alpha-numeric case-sensitive
password with 10 characters is startling. The second application was created to ensure that an IP Address being entered was in a valid format and did not fall within
any of the reserved address ranges.
I should stress that these are examples of some rather simple applications. For details of more complex applications that I have created for my clients please see my
profile or download a copy of my CV.
Guess whether the next number will be higher or lower than or the same as the number already displayed.
One point for each correct guess. The computer scores a point if you are wrong.
All numbers will be between 0 and 10.
