What is QualifiedCProgramming?

QualifiedCProgramming (QCP) is a verification tool for C programs using separation logic annotations. You annotate C functions with pre/postconditions and loop invariants, then QCP's symexec CLI generates Rocq Prover verification conditions as Coq files for automated or manual proofs. It handles real-world examples like linked lists, BST/AVL trees, arrays, and LiteOS primitives, outputting proof-auto, proof-manual, and goal files.

Why is it gaining traction?

QCP stands out with precompiled Linux/Windows binaries, Docker for easy setup, and a VSCode extension (QIDE) for real-time assertion checking during editing. Run-example scripts verify dozens of programs instantly, and MCP servers enable AI-assisted proving via Rocq-mcp. Unlike pure theorem provers, it bridges annotated C directly to structured proofs without full code extraction.

Who should use this?

Embedded C developers proving data structure invariants in kernels or RTOS like LiteOS. Formal methods researchers verifying pointer-heavy code such as AVL inserts or array merges. OS hackers needing separation logic for list queues or sort links without switching to Rust/ACL2.

Verdict

Worth trying for C verification experiments—solid Docker/VSCode flow and 50+ examples make onboarding fast despite 10 stars and 1.0% credibility score. Maturity lags (submodule quirks, manual Coq setup), so prototype proofs before production; pair with Rocq-mcp for LLM acceleration.
