Learn the KISS principle with practical C examples. See how simple, straightforward code is easier to understand, debug, and maintain than clever or over-engineered solutions.

Learn the YAGNI principle with practical C examples. See how building only what you need today avoids wasted effort, code bloat, and unnecessary complexity.
