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.

See the homework assignment page for your second programming assignment.
Today we will begin looking at how C uses pointers to pass values into and out of functions. In particular, we will look at how C functions pass arrays and structs. These examples are the basis for the new programming assignment.
Read the following chapter about pointers and memory.
Here is a link to today's video lecture.
NOTE: Starting Monday of next week, we will be meeting in a classroom on campus (we will meet in Anderson Bldg, Room 148). When we meet on campus, there will be no Zoom component to the class.
Today we will continue to look carefully at how C uses pointers to arrays and structs.
Here are a few useful explanations of the relationships between arrays, structs, and pointers.
Here are links to the two file comparison (diff) programs I mentioned in class.
