Demystify Your C++ Code with emmtrix C++ to C Compiler Online

December 12, 2023

We are pleased to announce a fantastic resource for developers and coders: emmtrix C++ to C Compiler (eCPP2C) online powered by Compiler Explorer at!

Compiler Explorer lets you run different compilers and shows you all intermediate results of the compilation process. Whether you’re an experienced developer or just starting out, it provides an invaluable platform for learning and honing your coding skills. You can enter your own code, choose between different programming languages (C, C++), and tweak compiler settings to see the effects in real time. We have integrated our tool eCPP2C into the framework so that you can convert C++ code to C code and also use Clang and gcc to view the internal representations (IR) of both languages. The way eCPP2C is implemented, the IR of the C++ and C program is almost identical with only minor differences that can be explored with the Compiler Explorer. See how different settings change the performance and efficiency of your code.
