Typedef
A readability tool that aliases long type declarations
Core Idea
Typedef does not invent a brand-new type so much as it gives an existing declaration a clearer name. In C, where declarations can become long quickly, that makes structs, function pointers, and repeated signatures far easier to read.
The point is readability, not a different memory model. That is why typedef often appears next to structs and enums: it helps the reader focus on meaning instead of syntax noise.
Why It Matters Here
Mathbong uses typedef as a practical tool for lowering the reading burden of C declarations. It helps beginners see the data model first instead of getting stuck on raw syntax.
