- Click the convert button.
- The resulting C++ code from the conversion will be displayed in the output box.
Examples
The following are examples of code conversion from C to C++ using this converter. Note that you may not always get the same code since it is generated by an AI language model which is not 100% deterministic and gets updated from time to time.
Example 1 - Is String Palindrome
Program that checks if a string is a palindrome or not.
C
C++
Example 2 - Even or Odd
A well commented function to check if a number if odd or even.

C++
Key differences between C and C++
| Characteristic | C | C++ |
|---|---|---|
| Syntax | C has a simpler syntax compared to C++. | C++ has a more complex syntax compared to C, with additional features such as classes and templates. |
| Paradigm | C is a procedural programming language. | C++ is a multi-paradigm programming language that supports procedural, object-oriented, and generic programming. |
| Typing | C is a statically typed language. | C++ is a statically typed language with support for dynamic typing through the use of templates and the 'auto' keyword. |
| Performance | C is known for its high performance and efficiency. | C++ is also known for its high performance and efficiency, with the added benefit of object-oriented programming features. |
| Libraries and frameworks | C has a smaller standard library compared to C++. | C++ has a larger standard library compared to C, with additional support for object-oriented programming. |
| Community and support | C has a large and active community with many resources available for learning and support. | C++ also has a large and active community with many resources available for learning and support. |
| Learning curve | C has a moderate learning curve, with a focus on low-level programming concepts. | C++ has a steep learning curve, with a focus on both low-level programming concepts and object-oriented programming. |
Frequently Asked Questions
How do I convert C to C++?
Paste your C code into the input box, confirm the languages are set to C and C++, and click Convert. CodeConvert AI analyzes your C code and generates equivalent C++ code in seconds, preserving the original logic and structure.
What are the main differences between C and C++?
C 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 C construct to its closest C++ equivalent. See the comparison table below for the key differences between C and C++.
Is the converted C++ code accurate?
The AI produces high-quality C++ code that preserves the behavior of your original C code and follows C++ conventions. It handles common patterns, data structures, and idioms for both C and C++. For large or performance-critical code, review and test the C++ output before using it in production.
Can I convert an entire C project to C++?
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 C++. Signing in for free raises the input limit to 25,000 characters per conversion for larger files.
Can I convert C++ back to C?
Yes. CodeConvert AI converts in both directions, so you can convert C++ to C just as easily using our C++ to C converter. Try the C++ to C Converter
Is the C to C++ 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 C++ without an account for up to 5 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.
