Lecture 8: writing a simple C program - Richard Buckland

We write a simple c program together during the lecture: "countdown" how many seconds are left until the first assignment is due? We (or rather Richard) make many mistakes.

Using top down design, functions, function prototypes, integer arithmetic, input/output.

we discuss program style, clarity, simplicity and complexity.

how to start to solve a problem. what to do when you get stuck. more on top down approach. # includes magic numbers variable names. why not to write amusing error messages. prjintf().
