说明：  实际上是两个project--wj&cpp3,wj是服务端程序，cpp3是客户端程序 编译前先在代码内相应位置写服务器地址，在客户端写发送的数据 编译生成两个执行文件wj.exe和cpp3.exe 先运行wj.exe等待连接，然后运行cpp3 -addre
(project is actually two-- wjcpp3, wj service software, cpp3 client program is compiled prior to the code to write the corresponding location server address, the client was to send the data compiler generated two and implementation document wj.exe cpp3.exe first running for wj.exe Link, and then run cpp3-addre)
