How to change c plus plus code into c

Question

How to change c plus plus code into c,is there any method or software

Answer 1

There's a software/tool by the name Comeau's C++ compiler. It generates an unmaintainable C code.

If you want to port it over to C and continue to develop it in C language, you will have to do it manually. If that's not the case, you can always continue to progress in C++ and convert the code to C when necessary.
