Once you've learned to program, one of the first difficulties you might encounter is developing large programs and dealing with the dreaded "spaghetti code". Programs with functions that comprise hundreds of lines of code, where you need to review parts multiple times just to figure out what you were working on. Or, you might wonder if there is a neater, more intuitive way to write parts of your program -- to make it easy to understand and to develop more complex programs quickly. Maybe you want your code to be able to do certain things, but you aren't sure how to do so without re-writing a lot of your base code. Do you know how to properly test your code? Have you ever made a change and unintentionally broken your program? In this class, I'll go over the basics of keeping your code neat, re-usable, and flexible. Topics include code formatting and documentation (boring, right?), helper methods, code testing, and programming patterns used in professional software engineering environments -- tools that are used in all kinds of circumstances from individual programmers to large software development teams. My goal is to be able to instruct new and experienced programmers alike. The techniques I plan to teach can be done in any object-oriented language.
