How to use the revision lecture

• The purpose of this lecture (and the slides) is to

emphasise the main topics of this course, and to help you structuring your revision of the module

• ver the Christmas break.
• Hopefully,

when revising the lectures, the courseworks and the lab exercises, you will have many “aha!”-experiences, where things become clear.

• Sure, exam marks exist, but please don’t forget that

the main purpose of studying is to learn.

Lectures and the book

Simply go through all lectures, and through the first 3 chapters of the book.

• It would be great if you could consider all the things

in the book we didn’t cover.

• Obviously, the additional examples won’t show up

in the exam, but they will help you.

• Perhaps for the three case studies (at the ends of the

first three chapters) there is not enough time now — perhaps over the summer you consider one of them, to refresh programming, and learn something about the three themes considered.

The lab sessions

• Programming is, especially in the beginning, mainly

doing.

• So going through all lab exercises is a good exercise.
• Likely you didn’t do all of them.
• If you actually did, now reworking them with your

enhanced understanding will further deepen your understanding.

• Finally, the book and the book’s webpage contain a

wealth of additional exercises. At the end of next week, answers will be provided for all lab exercises.

On the exam in general

• Three question, where you choose and answer two
• f them.
• Spend one hour for each of them — don’t overrun!
• Give yourself enough space.
• Don’t get stuck.

Typical parts of possible exam questions

Specific programming questions:

• 1. Write a function which takes two integer parameters

and returns their minimum.

• 2. Explain how to define a function in general.

General questions

• n

how to do (good) programming:

• 1. Discuss which members of a class should be private

and which public. Give some examples.

• 2. Explain the notion of a “data type”, and give some

examples.

Final remarks on the exam

Be as elaborate as possible (give me a chance to give you some marks(!)). Study the courseworks (and the solutions) well. Good luck! (Even better, if you don’t need it.)

Merry Christmas and a Happy New Year!

The End.
