This page documents what we do in class. It contains C programs that we will discuss in class, reading assignments from our textbook, simple homework exercises that you can work on for practice and exam preparation (not for credit), links to other sources of information, etc.

The reading assignments and practice problems are listed by the date on which they were assigned. The sample program files are listed by the date on which they were used. When you are viewing a source code page, you can use your browser's "File -> Save As..." menu item to save a copy of the code on your computer. It is a good idea for you to "play" with these example programs; compile them, run them, make simple changes to them and compile and run them again.
