socket编程-socket programming

1、自己编写的遵循SGIP1.1的短信网关模拟程序。仅供测试、学习。 2、该程序只实现了SGIP1.1协议的一部分。-1, I have written to follow the message gateway SGIP1.1 simulation program. For testing, learning. 2, the program only to realize the SGIP1.1 part of the agreement.

该程序模拟知乎，作为网上问答系统，用户能注册，登录，提问，回答，点赞，关注，取关，查找问题，等一系列操作,一个服务器端可以同时连接多个客户端，能够同步各个客户端操作结果。程序分为客户端和服务器端，用户gui采用mfc编写，通信方式为socket方式，开发环境为win7 vs2015，编译器v140.(The program simulates know almost as online quiz system, users can register, login, questions, answers, thumbs up, focus on, take off, find the problem, and a series of operations, a server can be connected to multiple clients simultaneously, it is possible to synchronize each client operating results. Program is divided into client and server side, the user using mfc gui written communication for the socket, the development environment for win7 vs2015, compiler v140.)
