Use this Skill to translate imperative C/C++ code into a functional Lean 4 model for deep, interactive theorem proving. It addresses scenarios where SMT solvers fail and generates machine-checked proofs for critical algorithms.

You should use Lean 4 for formal verification when SMT solvers fail, time out, or when the proof itself is the primary artifact for publication. Lean 4 provides a higher degree of assurance through interactive theorem proving for complex mathematical properties.

Yes, you can verify safety-critical C code by translating it into a Lean 4 functional model. This approach ensures mathematical integrity and generates machine-checked proofs suitable for certification when automated checks are insufficient.

Yes, you need an understanding of functional programming paradigms and Lean's proof calculus to effectively translate C to Lean 4. The translation process maps imperative logic into a functional model requiring interactive proof construction.

The translation of C to Lean 4 is not fully automated; it requires interactive theorem proving and understanding of Lean's proof calculus. It is designed for deep verification scenarios where automated tools like Dafny are insufficient, rather than simple syntax conversion.
