Common questions

Frequently Asked Questions

How do I convert OCaml to C?

Paste your OCaml code into the input box, confirm the languages are set to OCaml and C, and click Convert. CodeConvert AI analyzes your OCaml code and generates equivalent C code in seconds, preserving the original logic and structure.

What are the main differences between OCaml and C?

OCaml and C differ in syntax, type system, standard libraries, and common idioms, so copying code line for line usually will not compile. The converter maps each OCaml construct to its closest C equivalent. See the comparison table below for the key differences between OCaml and C.

Is the converted C code accurate?

The AI produces high-quality C code that preserves the behavior of your original OCaml code and follows C conventions. It handles common patterns, data structures, and idioms for both OCaml and C. For large or performance-critical code, review and test the C output before using it in production.

Can I convert an entire OCaml project to C?

You can convert OCaml files one at a time by pasting each file's code. For a full migration, convert each file and then review how classes, dependencies, and project structure map from OCaml to C. Signing in for free raises the input limit to 25,000 characters per conversion for larger files.

Can I convert C back to OCaml?
