Building a Driver Interface in C — A Complete Example
Build a complete driver interface in C combining Strategy, Factory, and DIP patterns. One interface, multiple hardware implementations, fully testable.
Liskov Substitution Principle (LSP) in C
Learn the Liskov Substitution Principle with practical C examples. See how interchangeable modules (like storage drivers) should behave consistently through a common interface.
Open/Closed Principle (OCP) in C
Learn the Open/Closed Principle with practical C examples using function pointers. See how to extend behavior without modifying existing, tested code.
Single Responsibility Principle (SRP) in C
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.
Software Quality Attributes Every Developer Should Know
Learn the key software quality attributes: maintainability, reliability, testability, readability, reusability, modularity, and more. Each term explained with simple C examples.
