This free online converter translates C++ source code into Lisp in three simple steps.
- Step 1
Add your C++ code
Type, paste, or upload the C++ code you want to translate.
- Step 2
Convert the code
Click Convert to translate the source code into Lisp.
- Step 3
Review the result
Review, copy, or download the resulting Lisp code from the output editor.

Example 2
Even or Odd
A well commented function to check if a number if odd or even.
C++ code
Lisp code
Language comparison
Key differences between C++ and Lisp
| Characteristic | C++ | Lisp |
|---|---|---|
| Syntax | C++ has a syntax that is similar to C, with some additional features such as classes and templates. | Lisp has a unique syntax that uses lots of parentheses and prefix notation. |
| Paradigm | C++ supports multiple paradigms, including object-oriented, procedural, and generic programming. | Lisp is a functional programming language that supports procedural and object-oriented programming as well. |
| Typing | C++ is a statically typed language, which means that variable types are checked at compile time. | Lisp is a dynamically typed language, which means that variable types are checked at runtime. |
| Performance | C++ is known for its high performance and is often used for systems programming and game development. | Lisp is not known for its performance and is often used for symbolic processing and artificial intelligence. |
| Libraries and frameworks | C++ has a large number of libraries and frameworks available, including Boost, Qt, and OpenCV. | Lisp has a smaller number of libraries and frameworks available, but there are still many useful ones such as Common Lisp Object System (CLOS) and Quicklisp. |
| Community and support | C++ has a large and active community with many resources available for learning and support. | Lisp has a smaller community than C++, but there are still many resources available for learning and support, including online forums and user groups. |
| Learning curve | C++ has a steep learning curve due to its complex syntax and many features. | Lisp has a moderate learning curve due to its unique syntax and functional programming concepts. |
Common questions
Frequently Asked Questions
How do I convert C++ to Lisp?
Paste your C++ code into the input box, confirm the languages are set to C++ and Lisp, and click Convert. CodeConvert AI analyzes your C++ code and generates equivalent Lisp code in seconds, preserving the original logic and structure.
What are the main differences between C++ and Lisp?
C++ and Lisp differ in syntax, type system, standard libraries, and common idioms, so copying code line for line usually will not compile. The converter maps each C++ construct to its closest Lisp equivalent. See the comparison table below for the key differences between C++ and Lisp.
Is the converted Lisp code accurate?
The AI produces high-quality Lisp code that preserves the behavior of your original C++ code and follows Lisp conventions. It handles common patterns, data structures, and idioms for both C++ and Lisp. For large or performance-critical code, review and test the Lisp output before using it in production.
Can I convert an entire C++ project to Lisp?
You can convert C++ 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 C++ to Lisp. Signing in for free raises the input limit to 25,000 characters per conversion for larger files.
Can I convert Lisp back to C++?
Yes. CodeConvert AI converts in both directions, so you can convert Lisp to C++ just as easily using our Lisp to C++ converter. Try the Lisp to C++ Converter
Is the C++ to Lisp converter free, and do I need to install anything?
Yes, it is free and runs in your browser with nothing to install and no IDE extension required. You can convert C++ to Lisp without an account for up to 2 conversions per day. Sign in for free for higher limits.
What are the benefits of signing in?
Signing in unlocks CodeConvert AI's Pro converter with more powerful AI models, a built-in chat assistant, code execution, saved conversion history, and personal notes. Every free account includes 5 credits and supports up to 25,000 characters of input per conversion, with no credit card required.
