clean code

Learn the DRY principle with practical C examples. See how eliminating code duplication with functions and macros makes code easier to maintain and less error-prone.

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.

Learn the Composition Over Inheritance principle with practical C examples. See how embedding structs and assembling behavior creates more flexible and maintainable code than deep hierarchies.

Learn Separation of Concerns with practical C examples. See how dividing code into distinct sections — each handling one concern — makes software modular, testable, and maintainable.

Learn the Law of Demeter (Principle of Least Knowledge) in C with examples. Reduce coupling by only talking to immediate friends, not reaching through struct chains.

Learn encapsulation and information hiding in C with examples. Use opaque pointers, static functions, and header/source separation to protect internal details.

Learn defensive programming in C with practical examples. Validate inputs, prevent buffer overflows, use assertions, and handle errors gracefully.

Learn the 5 most common error handling patterns in C: return codes, output parameters, goto cleanup, error callbacks, and error structs. With practical examples.
