GetVersion

Windows 提供了GetVersionEx 函数来返回当前操作系统的版本信息

#include "stdafx.h"
#include "windows.h"
#include "iostream.h"
int main(int argc, char* argv[])
{
    OSVERSIONINFO os={sizeof(os)};
    GetVersionEx(&os);
    cout<<os.dwBuildNumber<<endl;
    cout<<os.dwMajorVersion<<endl;
    cout<<os.dwMinorVersion<<endl;
    cout<<os.dwOSVersionInfoSize<<endl;
    cout<<os.dwPlatformId<<endl;
    cout<<os.szCSDVersion<<endl;
    return 0;
}
