How do I convert a C++ file to a C file with LetsConvert?

Upload your .cpp file to the converter, choose C as the destination format, and click 'Convert'. The tool will generate a .c file with adjusted syntax—for example, converting C++ class definitions to C structs and replacing dynamic memory allocation with malloc/free. Review the output for any unsupported features and manually adjust as needed.

Why convert from C++ to C instead of using C++ directly?

C is a simpler, more portable language that can be compiled on virtually any platform, including embedded microcontrollers and legacy systems without C++ runtime support. Converting to C also reduces code size and improves compatibility with C-only libraries and coding standards.

How are C++ classes and object-oriented features preserved during conversion?

The converter maps classes to structs and functions to function pointers, emulating method calls by passing the struct pointer as the first argument. Virtual functions become entries in a function pointer table, and simple template functions are instantiated as multiple typed versions. Complex features like exceptions, inheritance, and RTTI cannot be fully automated and require manual restructuring.

Is CPP-TO-C free to use?

Yes, CPP-TO-C on LetsConvert is 100% free with no registration or hidden fees required.

Does this converter work on mobile phones and tablets?

Yes! CPP-TO-C works seamlessly across iPhone, Android, iPad, Mac, Windows, and Linux browsers without installing any app.

Is there any software installation required?
