SOLID principles

Learn the Interface Segregation Principle with practical C examples. See how splitting bloated interfaces into small, focused ones prevents unnecessary dependencies.

Learn the Dependency Inversion Principle with practical C examples. See how depending on abstractions (function pointers) instead of concrete implementations makes code flexible and testable.

Learn the Liskov Substitution Principle with practical C examples. See how interchangeable modules (like storage drivers) should behave consistently through a common interface.

Learn the Open/Closed Principle with practical C examples using function pointers. See how to extend behavior without modifying existing, tested code.

Learn the Single Responsibility Principle with practical C examples. See how splitting a module into focused responsibilities makes code easier to maintain, test, and reuse.
