单词助手（可联网）

基本功能

1. 可实现对本地词库添加、删除单词功能
2. 可实现查词功能，根据英文查释义，优先从本地词库查询，如果本地词库没有就自动网上查询，并将其添加至本地词库
3. 可实现学习功能，每天50词，可分批次学习，并有根据单词选择释义和根据释义写单词两种学习方式
4. 可实现错误回顾功能，在学习过程中出错的词都保存在文件中，用于下次回顾
5. 可实现服务器多并发

涉及技术

1. C/C++
2. 文件操作
3. socket网络编程
4. linux系统编程

需要工具

1. openssl
2. curl
3. 百度翻译api

注：openssl和curl安装在服务器（阿里云或腾讯云服务器）中，百度翻译api可在百度翻译平台免费申请标准版，好像有词量限制，但也够用了。具体安装步骤网上教程很多，此处不做赘述。服务器详情请参考https://blog.csdn.net/weixin_44690490/article/details/104342427

代码逻辑

添加：定义一个结构体，包含单词和释义两个字符数组，并对其赋值，再将这个结构体写进词库文件尾部
删除：先将词库文件a更名为b，在读取整个词库文件b，查找出需要删除的单词word，再创建一个与词库文件之前名称a相同的文件c，此时c就成为了词库文件，再将word前后的数据写进文件c中，最后删除文件b
学习：先读取文件数据，在随机抽取其中一个词，按照需要的学习方式输入答案，答错就将这个单词保存在vector容器中，无论答错答对今日任务量都减一，在退出程序前将当前完成量以及时间记录在文件中，在下次启动程序时判断日期是否发生变化，是则将文件中的数据清零，否则保持不变。（具体整个学习方式的逻辑很简单，没有解释点）
回顾：在学习中出错的单词都记录在vector容器中，在学习完后可继续进行错误回顾，回答正确就将该单词进行尾删，仍然错误继续存入容器中。如果学习完成后退出了程序，此时就将vector容器中的数据写入文件中，便于下一次回顾。
查找：先读取词库，如果在词库内找不到你想要的单词，此时判断电脑是否联网，已联网就连接并将单词发送给服务器，服务器通过百度翻译api向百度翻译发起请求，百度翻译相应后就将释义返回给服务器，服务器再将其返回给客户端
服务器多并发：创建一个线程p，主线程用于connect连接，p线程用于与客户端的数据通信
