Inbal Levi :: Let's talk about C++'s Abstraction Layers

Presented at Core C 2023 conference. Abstraction Layers are one of the strongest tools we're using for software development. Even though being taught during the first semester of a Computer Science undergraduate and is widely used throughout the everyday workflow of software development, a lot of logic bugs occur by wrong usage of this concept. During this talk, we will define and explore the C abstractions layers, through both the mental model as reflected in papers, as well as through past mistakes and bugs. We will introduce some ground rules to encourage more correct usage of this concept, by extrapolating from examples from the latest C 23 and C 26 standards' features. Finally, we will review a proposal for addressing ISO C WG21 committee work. ===== Inbal Levi is a Lead Software Engineer at MPGC Services Ltd (Millennium) with a passion for high performance, readability, and software design.
