Name: Zhiyuan Ning USC ID:1808644153 Email:zhiyuann@usc.edu Description: I cite and look up the code from Beej's Guide. Because some of the function does not support in C langauage, I use the C++ language to program this assignment. I also cite and look up the code from: https://www.cnblogs.com/leezheng/p/8030011.html All of the functions and server works well. To seperate the database and calcserver, I initialize two sockets to transfer. The output corresponds to the .pdf demo.
