如何知道何时找到子文件夹目录的末尾？c++

#include <iostream>
#include <filesystem>

void traverseDirectory(const std::filesystem::path& path) {
    for (const auto& entry : std::filesystem::directory_iterator(path)) {
        if (entry.is_directory()) {
            std::cout << "Directory: " << entry.path().string() << std::endl;
            traverseDirectory(entry.path()); // 递归遍历子文件夹
        } else {
            std::cout << "File: " << entry.path().string() << std::endl;
        }
    }
}

int main() {
    std::filesystem::path directoryPath = "your_directory_path";
    traverseDirectory(directoryPath);
    return 0;
}
