I tried to follow the example given in both answers and it might be worth noting that it appears as though std::filesystem::directory_entry has been changed to not have an overload of the << operator. Instead of std::cout << p << std::endl; I had to use the following to be able to compile and get it working:

#include 
#include 
#include 
namespace fs = std::filesystem;

int main() {
    std::string path = "/path/to/directory";
    for(const auto& p : fs::directory_iterator(path))
        std::cout << p.path() << std::endl;
}

trying to pass p on its own to std::cout << resulted in a missing overload error.
