CHALLENGE: 

When a user registers they need a secure password which has specific requirements (see task). Ensure the password that is entered by the user is 'secure'. Enable this feature within the registration process

SUGGESTED SOLUTION / CODE: 

Note: See if you can do better (and you should be able to). The solutions provided are basic, and allow for discussion on possible alternative methods and solutions.

Design Tools

Designing something or writing out some pseudocode before you actually write code is always a good idea! Get in to the habit of doing so! You can draw your flowchart here and screenshot it.

Try it yourself

Testing Table

You may want to read a little about Testing first. A teacher may go through some examples with you. Feel free to fill in the test table here, and screenshot it in to your powerpoint. Testing is absolutely essential once you have created a program!
