Hello,
expert in Fortran and C++ programming. I can convert your attached Fortran code to C++. Please have a look at my history here on Freelancer and you will see that I've worked on various Fortran projects (I have more than 15 years of Fortran programming experience and a background in Engineering).
Please let me know what C++ compiler do you want me to use and on what Operating System. Also, give me more details about the UI you want implemented.
Thanks,
Paul
