Comment-driven code generation
The prompt
/* Ask the user for their name and say "Hello" */
Expected result
A working code snippet that prompts for a name and prints a greeting — generated purely from a comment describing the intent.
Why it works
Demonstrates comment-driven code generation: a plain comment describing intent is often enough on its own, without an explicit "write code that does X" instruction — useful as an inline pattern inside an actual codebase or IDE autocomplete.
