几个星期以来，我一直对制作一个显示XBOX控制器输入的程序感兴趣，而且我一直有很多问题。我正在使用Code :: Blocks，而XInput.h有SAL注释，我已经读过GNU GCC编译器，不知何故不熟悉。我坚持用Code :: Blcoks编码，所以我决定链接Visual Studio中的包含文件（我已经读过这将解决一些与SAL相关的问题）。现在我有了新的问题。我使用的代码来自https://lcmccauley.wordpress.com/2014/01/05/gamepad-input-tutorial/的教程，由于我也包含了新文件夹，我在第81行的vcruntime.h中遇到了错误。另一个错误是winnt.h，第2444行。我现在完全没有想法。
P.S：请不要因为没有注意到一些明显的解决方案而杀了我。我还是个初学者。谢谢！以下代码：
