C++ 不用wmi 获取所有硬件名称和序列号包括主板，内存，硬盘，显示器

在 C++ 中，可以使用 Windows Management Instrumentation (WMI) 来获取计算机硬件的信息。以下是一个示例代码，可以获取主板、内存、硬盘和显示器的名称和序列号：

#include <iostream>
#include <windows.h>
#include <comdef.h>
#include <Wbemidl.h>

#pragma comment(lib, "wbemuuid.lib")

其中 `Win32_BaseBoard` 是获取主板信息的 WMI 类，`Win32_PhysicalMemory` 是获取内存信息的 WMI 类，`Win32_DiskDrive` 是获取硬盘信息的 WMI 类，`Win32_DesktopMonitor` 是获取显示器信息的 WMI 类。以上代码可以在 Windows 平台上编译运行，并输出对应硬件的名称和序列号。
