You can quickly get the args into a vector like this:

auto args = std::vector<std::string_view>(argv, argv + argc);

Checking equality etc directly instead of using strcmp stuff is better. There are libraries available for handling command line args too.

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.
