1.首先我们打开一个项目，找到资源管理器，并找到如下图右边所示的 解决方案~ 然后右键
右键进入 属性 页面
2.最后在 调试源文件 下可以看到具体路径。
二 按照路径我们进入 include 文件夹 并在里面新建文件夹 bits
进入后再添加头文件 stdc++.h （可以在桌面创建 文本文档 并把头文件的内容复制进去，再改一下文件名，头文件的内容我会放在最后）
三 按照上面的步骤操作后，重启VS进入项目，或许有些人（我就是其一）会发现VS依然显示无法打开<bits/stdc++.h>这个头文件，在经过一番查阅之后，问题出现在对 stdc++.h重命名这步上。在win10里，文件名的后缀默认是隐藏的，所以下面给出具体解决方案（要是一切运行正常的同学就可以跳过这一步了）
1.首先按照之前找到的路径进入 include 将光标移动到我们新建的文件夹 bits 上并单击，上方会出现窗口，然后我们继续点击 查看，进入一下页面
然后勾选 文件拓展名 就可以了，再进入 bits 就可以看到文件的后缀，在重新进行修改为 stdc++.h就可以了，之后重启VS就大功告成了
