Hints for the Introduction to Programming course exam on 15.10.2008

The course exam is on Wednesday 15.10. from 9:00 to 12 (2.5 hours of time to answer) in the Exactum auditorium A111.

Important things, hints, etc.

• You should be able to use statements and expressions in programming. There will be no questions like "what is a while statement like" or "program this and that using a for statement [or while statement etc.]"
• You will not be asked to program anything that requires exact formatting of output (as in the question 6)
• Input must be read using a Scanner. The details of constructing a Scanner aren't important, but you need to know how it's used.
• You should be able to write methods and pass parameters to them. Also, be prepared to explain these concepts.
• Make sure you know how to write methods that are "main program's little helpers" and accessor methods. Overloading should be understood.
• You must know how to program classes and objects, and be able to explain their usage - using the right terms, too. Especially the idea of encapsulation is important!
• You should remember the String methods length(), equals(String) and compareTo(String).
• You should know how to program both linear (sequential) and binary search. The names of these algorithms need to be remembered.
• You should be able to order an array somehow - knowing any particular named way isn't required, though.
• In the exam it is enough to understand and be able to handle arrays of type int, double and String. (But the Advanced Course in Programming expects that you understand more of them, like using your own objects in an array and having an array as an instance variable...)

Other advice:

• Keep in mind what an exam is really about and what it isn't: An answer should convince the inspector - or at least fool him to believe - that the student knows enough. Think of the psychology of the inspector, don't think of your own enthusiasm or anxiety! An exam is like a performance that you give to the inspector.
• It is wise to first answer the questions that you know you can answer. After that, if there's time, you can try the others too...
• To speed up the grading process, each answer is written on a separate paper. That is because each inspector checks all of the answers to a single question.
• It is wise to use descriptive variable names and write clear code! That way the inspector might understand what you mean with a solution, even if it isn't entirely correct. Remember to indent sub-statements and inner blocks!
• You can abbreviate "System.out.println" with "S.o.p". Note that this is assumed to mean println(), not print().
• The exercise tasks are important. Often an exercise question has appeared in the exam as an exact copy, or with only minor modifications. The following types of questions are NOT asked in the examination: 1, (2), (3), 5, 6, 8, (9), (14), (24), 28, 29.
• All of the old exam questions can be found in the old course pages. The old example solutions need to be taken with a grain of salt, though, because the course is constantly evolving. If you are not happy with your grading this year, you may not base your argument on an old example solution ;-)
