如何使用编程语言（如C++）实现创建一个新的目录并生成一个文本文件的操作，然后删除文件夹

在C++中，你可以使用`std::filesystem`库来进行文件和目录操作。这个库在C++17及以上版本中可用。以下是基本步骤：

1. **创建新目录**:

   #include <filesystem>
   
   namespace fs = std::filesystem;
   
   void createDirectory(const std::string& directoryPath) {
       if (!fs::exists(directoryPath)) {
           fs::create_directory(directoryPath);
           std::cout << "Directory created at " << directoryPath << std::endl;
       } else {
           std::cout << "Directory already exists at " << directoryPath << std::endl;
       }
   }

2. **生成文本文件**:

   void writeToFile(const std::string& filePath, const std::string& content) {
       std::ofstream file(filePath);
       if (file.is_open()) {
           file << content;
           file.close();
           std::cout << "File written to " << filePath << std::endl;
       } else {
           std::cerr << "Failed to open file for writing." << std::endl;
       }
   }

3. **删除文件夹**:

   void deleteDirectory(const std::string& directoryPath) {
       if (fs::is_directory(directoryPath)) {
           if (fs::remove_all(directoryPath)) {
               std::cout << "Directory deleted at " << directoryPath << std::endl;
           } else {
               std::cerr << "Failed to delete directory." << std::endl;
           }
       } else {
           std::cerr << "Provided path is not a directory." << std::endl;
       }
   }

记得在实际使用时处理可能出现的异常。
