Short description

Create a polished CLI app (e.g., student record system or inventory manager) with structs, file persistence, dynamic memory, input validation, a Makefile, and README. Handle errors and free all allocations.

Steps

1. Design features and data model.
2. Implement modules and persistence.
3. Add validation and cleanup.
4. Document build/run steps and test flows.

Final project scope

1. App idea + features list
2. Modular .h/.c design
3. Struct-based records
4. Dynamic array or linked list
5. File save/load
6. Menu-driven CLI
7. Input validation + error handling
8. Makefile + README
9. Memory clean on exit
