背单词工具(C++)
功能分析
- 生词本管理：
- 创建生词本文件：在构造函数中创建了“生词本.txt”“背词历史.log”“历史记录.txt”三个文件。
- 添加单词：用户可以输入单词、词性和解释，将其添加到生词本中。
- 查询所有单词：展示生词本中所有的单词、词性和翻译。
- 精确查词：用户可以选择按照单词、词性或中文解释进行查词，并显示查询结果。
- 删除单词：根据用户输入删除生词本中的特定单词。
- 背词功能：
- 背生词：从生词本中读取单词进行背诵，背诵完成后将生词从生词本中删除，并将相关信息添加到背词历史中。
- 历史记录查询：
- 根据时间查历史记录：用户输入年月日，查询该日期的背词历史记录，并将其保存到历史记录文件中。
- 查询历史背词：展示历史记录文件中的内容。
- 其他功能：
- 更新日志：输出新增功能的说明。
- 总的服务界面：提供菜单界面，用户根据序号选择相应的服务。
