[C++知识库]精简版的贪吃蛇教程c++图形库实现最简单不看后悔（一个简单框架可改）

实现需要修改两个玩意第一个下载easyx https://blog.csdn.net/Daisyes/article/details/81333529?ops_request_misc=%257B%2522request%255Fid%2522%253A%2522162642722916780274136998%2522%252C%2522scm%2522%253A%252220140713.130102334…%2522%257D&request_id=162642722916780274136998&biz_id=0&utm_medium=distribute.pc_search_result.none-task-blog-2_alltop_positive~default-1-81333529.first_rank_v2_pc_rank_v29&utm_term=easyx%E4%B8%8B%E8%BD%BD&spm=1018.2226.3001.4187
第二个需要修改编译器内容
