新手遇到找不到文件这个问题求求解答

0

我是刚刚接触c语言的人,复制了一段代码·,想玩一下贪吃蛇但是,显示找不到这个文件D:\CodeBlocks\project\1-3\1-3\main.c|4|fatal error: graphics.h: No such file or directory|
,用的是codeblocks这个软件,求求解答,拯救一个新手吧

你需要安装 EasyX。

在 codeblocks 下配置 easyx 有些麻烦,可以参考:https://codebus.cn/bestans/easyx-for-mingw

在 vs 下配置 easyx 比较简单,直接下载安装即可。初学者推荐使用 vc2010。从这里下载: https://appzip.cn/vc2010 ,里面有个详细的图文安装步骤。
