void create_file(const fs::path& p) { std::ofstream o{p}; }
int main()
{
    const fs::path dir{"tmp_dir"};
    fs::create_directory(dir);
    create_file(dir / "one");
    create_file(dir / "two");
    create_file(dir / "three");
    for (const auto& file : fs::directory_iterator(dir))
    {
        // 显式转换
        std::cout << get_stem(file.path()) << '\n';
        // 隐式转换
        std::cout << get_stem(file) << '\n';
    }
    fs::remove_all(dir);
}
