im new in c++ and i am creating a version of cat for practicing what i have learned so far. What im doing for managing the command line arguments is converting them to library strings and then using them, but now i have the doubt if it is the correct / most optimal way to do it

    Use std::string_view to sort of get the safety of std::string without copying the contents (just in general make sure the original c string won’t get freed or overwritten, which won’t happen to argv in your case).

    Or just std::string and yolo, the overhead of copying the contents is negligible in your use case.

        If they are just practicing it isn’t a problem, C++17 is already 6 years old and the open source community should get onboard imo

            I’m not talking about professional projects. OP asked about making a pet project in C++.

            Also, a lot of opensource software could jump forward in term of standard required ; I’m not saying that no professional project uses opensource library, just that we should start moving forward if we don’t want to get stuck with old versions
