Struct-Free Dynamic Arrays in C: A Minimal Pointer-Based Approach

This C programming technique demonstrates how to implement generic dynamic arrays without struct overhead by using a two-pointer strategy to track length and data separately. By calculating capacity on demand using power-of-two thresholds instead of storing it explicitly, the approach minimizes memory overhead while maintaining type-generic functionality. This pattern exemplifies advanced C optimization suitable for systems programming where memory efficiency and implementation simplicity are paramount.
