TCP套接字编程实现：

开发一个多线程服务器，它能并行服务于多个请求。

提示：

用Java或c/c++语言开发；

通过调用操作系统API接口创建线程；

假定3个客户端，客户端i发送“Hi,God”,服务器回答“What can I do for you, my son i”，客户端收到后显示服务器回答。

分别用TCP和UDP两个协议来测试，端口号自定义

-TCP socket programming: Develop a multi-threaded server, it can serve multiple requests in parallel. Tip: Use Java or c/c++ language development　by calling the operating system API interface to create threads　assume 3 client, the client i send " Hi, God" , the server replied " What can I do for you, my son i"　, displayed after the client receives the server reply. TCP and UDP were used to test the two protocols, port numbers Custom
