Information about the First Test

The first test in this course will take place on Friday, February 20. It will cover material from the first four chapters as well as the lab and assignments. You can expect a mixture of different types of problems: definitions, short-answer essays, longer conceptual essays, and programming. Programming questions might, for example, ask you to use an abstract data type to accomplish some task or to write an implementation for an ADT. You should expect at least one question where you are given some code and asked to analyze its run time. You are not responsible for any details of C++ templates and the standard template library, but you should understand the basic concepts (which might be tested in definitions and essay questions).

Important terms and ideas for this test include:
