Multi-File Projects
Headers and translation units.
Why Split Files
Real programs do not live in one .c file. Splitting code into multiple files:
- Groups related functions together
- Lets the compiler rebuild only what changed
- Makes code reusable across projects
- Lets a team work without constant conflicts
Understanding how the pieces link is essential.
Translation Units
Each .c file, after the preprocessor expands its #includes, becomes a translation unit.
The compiler turns each translation unit into an object file (.o) independently. It does not know about other files at this stage.
