CS161 – Spring 2007
Exam 3 Study Topics
On the day of the exam, be sure to bring your notes
and your book. The written part of the
exam will be worth 75 points and will be closed notes, closed book and closed
neighbor. The on-line part of the exam
will be open book and open notes (your own only, of course) but still
absolutely closed neighbor! Please note
that although the official “online” portion of the test will only be 25 points,
a large portion of the points in the written section involve writing code
statements and segments. You need to
know your syntax.
Your exam might include the following types of
questions:
- Multiple Choice
- Fill in the Blank
- True/False
- Matching
- Definitions
- Identify the problems
in a piece of code
- Describe the output of
a piece of code
- Write code segments
Important topics to review:
- Although the test
questions will not be specifically aimed at these topics, you will still
need to know about the following in order to write and interpret the
programs on the test:
- Different data types
- Input/Output
- How to evaluate and
write arithmetic expressions (operator precedence, etc.)
- Arithmetic operators
- How to write and
evaluate Boolean expressions (meaning, precedence)
- Conditionals (if,
if/else, nested ifs, switch statements)
- Loops (while,
do/while, for)
- Classes and
methods –instance data,
parameters, return values, etc.
- Arrays
- How to declare &
instantiate arrays
- How to put values into
arrays
- How to get values out
of arrays
- Using arrays in
conjunction with loops
- Passing arrays as
arguments to functions
- Sorting and Searching
- Be familiar with the
terms and concepts
- Be able to trace
through sorting code and understand what’s happening
- Be familiar with the
algorithms that we’ve discussed in class (selection, bubble, insertion
sorts).
- Be sure that you
understand the content of the programs that we’ve written in class, labs
and homework assignments.
Study Tips:
The best source of practice is the problems in your
book. Remember that the answers to
the Quick-Check questions are in the back of the book.
Form study groups if possible. Practice doing the problems from the back of
the chapters individually, then compare your answers.
Practice writing and interpreting code segments.
