namespace fs = std::experimental::filesystem;

int main()
{
fs::path p = fs::current_path();

std::cout << "The current path " << p << " decomposes into:\n"
<< "root name " << p.root_name() << '\n'
<< "root directory " << p.root_directory() << '\n'
<< "relative path " << p.relative_path() << '\n';
}
