Abstract:In today's increasingly serious information security problems, we have designed a LAN chat room system based on C++ for the purpose of safely solving the internal communication and communication problems within the enterprise. This article focuses on how to implement secure and convenient instant messaging problems that support multiple users under the LAN. Based on the traditional software engineering design method, combined with the basics of program design and network data transmission technology, the C/S architecture design is used to implement a local area network chat room system suitable for small and medium-sized networks. The system is easy to operate and has stable operation. Performance and good extensibility, users respond well through actual testing.
