C Sample Files
C (.c) source files represent low-level, compiled code used in systems, embedded software, and performance-critical tooling. Use sample C files to test parser behavior, static analysis, and native build pipelines.

Checksum Verification
Use checksums to confirm file integrity after download.
shasum -a 256 your_file_name_here
# Compare output with SHA256 values listed above.
Where is the machine-readable manifest?
Use the manifest when you need stable names, SHA256 values, and URLs for automation.
Use in code — curl, Python, Node, wget
Copy any snippet directly into scripts, test suites, or CI pipelines. All URLs are stable and publicly accessible with no auth required.

Validation Methodology
- Validate syntax-highlight pipelines and file-type detection.
- Test parser robustness for larger source samples.
- Confirm linting/formatting tools handle encoding correctly.
