I recently discovered a pretty good discussion on what “good code” is. The original author, Bill Carlson, specified quite a few good points. Points that according to him make the code good. Before I list the summary of the points, let me just say that if you are interesting in writing quality code, I think you should (you must) read Steve McConnell’s Code Complete. It will open your eyes. It opened mine. 🙂 (See my review in Books I Recommend.)

Attributes of “Good Code:”

• High “signal to noise” ratio.
• Minimal algorithmic complexity.
• Lack of “cuteness”.
• Use of most primitive technology required.
• Appropriate optimization.
• Architectural simplicity.
• Specificity (avoiding over-generalization).
• When vs. How comments. Knowing how to use a class: useful. Knowing when to use a class: priceless.
• Appropriate quality bar.
• 100% reachable code.
• Lack of cut-n-paste.
• Lack of redundency.
• Visual clarity. Is the code easy to read?
