用c++写一段判断windows系统版本的程序

### 回答1：

#include <stdio.h>
int main(){
char version[10];
printf("请输入您的Windows系统版本号：");
scanf("%s",version);
if(strcmp(version,"Windows 10")==0){
printf("您的Windows系统版本为Windows 10");
}
else if (strcmp(version,"Windows 8")==0){
printf("您的Windows系统版本为Windows 8");
}
else if (strcmp(version,"Windows 7")==0){
printf("您的Windows系统版本为Windows 7");
}
else{
printf("抱歉，您的Windows系统版本暂时无法识别");
}
return 0;
}

以下是用C语言编写的判断Windows系统版本的程序：

#include <stdio.h>
#include <Windows.h>

int main()
{
    // 获取操作系统版本信息
    OSVERSIONINFO osInfo;
    ZeroMemory(&osInfo, sizeof(OSVERSIONINFO));
    osInfo.dwOSVersionInfoSize = sizeof(OSVERSIONINFO);
    GetVersionEx(&osInfo);

    // 判断操作系统版本
    if (osInfo.dwMajorVersion == 10 && osInfo.dwMinorVersion == 0)
    {
        if (osInfo.wProductType == VER_NT_WORKSTATION)
            printf("Windows 10");
        else
            printf("Windows Server 2016");
    }
    else if (osInfo.dwMajorVersion == 6 && osInfo.dwMinorVersion == 3)
    {
        if (osInfo.wProductType == VER_NT_WORKSTATION)
            printf("Windows 8.1");
        else
            printf("Windows Server 2012 R2");
    }
    else if (osInfo.dwMajorVersion == 6 && osInfo.dwMinorVersion == 2)
    {
        if (osInfo.wProductType == VER_NT_WORKSTATION)
            printf("Windows 8");
        else
            printf("Windows Server 2012");
    }
    else if (osInfo.dwMajorVersion == 6 && osInfo.dwMinorVersion == 1)
    {
        if (osInfo.wProductType == VER_NT_WORKSTATION)
            printf("Windows 7");
        else
            printf("Windows Server 2008 R2");
    }
    else if (osInfo.dwMajorVersion == 6 && osInfo.dwMinorVersion == 0)
    {
        if (osInfo.wProductType == VER_NT_WORKSTATION)
            printf("Windows Vista");
        else
            printf("Windows Server 2008");
    }
    else if (osInfo.dwMajorVersion == 5 && osInfo.dwMinorVersion == 2)
    {
        if (GetSystemMetrics(SM_SERVERR2))
            printf("Windows Server 2003 R2");
        else if (osInfo.wSuiteMask & VER_SUITE_WH_SERVER)
            printf("Windows Home Server");
        else if (osInfo.wProductType == VER_NT_WORKSTATION && GetSystemMetrics(SM_TABLETPC))
            printf("Windows XP Tablet PC Edition");
        else
            printf("Windows Server 2003");
    }
    else if (osInfo.dwMajorVersion == 5 && osInfo.dwMinorVersion == 1)
        printf("Windows XP");
    else if (osInfo.dwMajorVersion == 5 && osInfo.dwMinorVersion == 0)
        printf("Windows 2000");
    else
        printf("Unknown");

    return 0;
}

该程序使用`GetVersionEx`函数获取操作系统版本信息，并通过判断版本号和产品类型来确定具体的Windows系统版本。在输出结果时，每个版本对应着相应的消息进行打印。

下面是一个使用C语言编写的示例程序，用于判断Windows系统的版本。

#include <windows.h>
#include <stdio.h>

int main()
{
    // 获取操作系统版本信息
    OSVERSIONINFOW osVersion;
    osVersion.dwOSVersionInfoSize = sizeof(OSVERSIONINFOW);
    if (GetVersionExW(&osVersion))
    {
        // 判断Windows系统版本
        if (osVersion.dwMajorVersion == 5 && osVersion.dwMinorVersion == 0)
        {
            printf("Windows 2000\n");
        }
        else if (osVersion.dwMajorVersion == 5 && osVersion.dwMinorVersion == 1)
        {
            printf("Windows XP\n");
        }
        else if (osVersion.dwMajorVersion == 5 && osVersion.dwMinorVersion == 2)
        {
            printf("Windows Server 2003\n");
        }
        else if (osVersion.dwMajorVersion == 6 && osVersion.dwMinorVersion == 0)
        {
            printf("Windows Vista\n");
        }
        else if (osVersion.dwMajorVersion == 6 && osVersion.dwMinorVersion == 1)
        {
            printf("Windows 7\n");
        }
        else if (osVersion.dwMajorVersion == 6 && osVersion.dwMinorVersion == 2)
        {
            printf("Windows 8\n");
        }
        else if (osVersion.dwMajorVersion == 6 && osVersion.dwMinorVersion == 3)
        {
            printf("Windows 8.1\n");
        }
        else if (osVersion.dwMajorVersion == 10 && osVersion.dwMinorVersion == 0)
        {
            printf("Windows 10\n");
        }
        else
        {
            printf("Unknown Windows Version\n");
        }
    }
    else
    {
        printf("Failed to get OS version\n");
    }

    return 0;
}

该程序使用了Windows提供的API函数`GetVersionExW`获取操作系统版本信息，然后根据版本号进行判断，输出相应的提示信息。
