Hi ,
I am a C/C++/Python Developer having 8 yrs of experience. I can convert your C code to C++ code using more efficient c++ standards like c++11/14. I went through your code in GitHub and found that it's implemented using graph theory. Regarding plagiarism, I will rewrite your entire code in C++ and you can check my code using any plagiarism detection tools available on internet and if the any copied content found in my code, I will do this project free of cost , with no questions asked. Regards.
