easyX是什么
EasyX Graphics Library 是针对 Visual C++ 的免费绘图库，支持 VC6.0 ~VC2019，简单易用，学习成本极低，应用领域广泛。目前已有许多大学将 EasyX 应用在教学当中。
在编译器中所需要包含的头文件 #include <graphics.h>
安装easyX
首先，我们要实现这个项目，需要用到图形库，我们选择用简单easyX的图形库，可以去到官网下载，可点击下面的链接。
点击easyX官网
然后再点击下载
下载完之后，我们点击easyX安装，刚开始直接点下一步，然后进入到以下页面
这个呢，选择自己相应的编辑器，然后选择安装，这里以vs2019为主(用其他编辑器的都一样的，点安装即可)，也可以安装easyX文档，有助于自己学习。
在vs2019中创建一个新的项目
如果有不知道vs2019怎么用的，可以看这篇文章

项目所需要素材
如果想需要素材资源的，可以通过我的资源里面下载
太空人素材资源
解决在vs2019中使用图形库遇到的错误
当我们都准备好之后，编译时却发现了以下的报错
这是因为我们使用的字符集不匹配，所以函数才会出现这样的错误
要解决这个问题很简单，这里就使用设置项目属性的方法来解决这个问题。
然后点击属性
选择多字节字符集，然后点击确定即可
解决函数警告问题
解决方法和上面的一样，打开项目属性
太空人表盘示例
这样我们的太空人表盘就实现了
