Where are the answers to the exercises?

There are none. In the real world no one is going to pass you an answer booklet, or check your work for you. Ensuring your code does as you intended is an essential skill to learn. Some readers ask for the answers because they are concerned that they might not have done the right thing. But testing the right thing in this case is just testing understanding of the question; a pretty pointless exercise. Additionally there is not always a wrong or right way to approach the Bonus Marks. They are intended as suggestions to help people check their understanding, or to explore other ideas and thoughts.

If you want to do a Bonus Mark question but are unsure what it means, feel free to send me an e-mail and I will try to clarify it! Otherwise don’t fret over the answer. Giving it a try is the important part, not getting it right!
