是否有C ++功能关闭计算机？

Is there a C++ function to turn off the computer? And since I doubt there is one (in the standard library, at least), what's the windows function that I can call from C++?

是否有C ++功能关闭计算机?既然我怀疑有一个(至少在标准库中),我可以用C ++调用什么是windows函数?

On windows you can use the ExitWindows function described here:

在Windows上,您可以使用此处描述的ExitWindows函数:

and here's a link to example code that does this:

Use the following, assuming you have the privileges):

假设您拥有以下权限,请使用以下命令:

ExitWindowsEx (EWX_POWEROFF | EWX_FORCEIFHUNG,
    SHTDN_REASON_MINOR_OTHER);

This will cause power off while giving applications a chance to shut down (if they take too long, they'll be terminated anyway).

这将导致电源关闭,同时给应用程序关闭的机会(如果它们花费太长时间,它们将被终止)。

It's part of the Win32 API rather than standard C++ but that's because C++ provides no way to do this directly.

它是Win32 API的一部分,而不是标准的C ++,但这是因为C ++无法直接执行此操作。

#3

You can shutdown by utilizing the system() function.

您可以使用system()函数关闭。

for Windows

system("shutdown -s");

for Linux

system("poweroff");

system("init 0");

#4

You can do this in Windows, by calling the ExitWindowsEx function.

您可以通过调用ExitWindowsEx函数在Windows中执行此操作。

#5

yes! for Windows XP:

是!对于Windows XP:

#include <stdio.h>
#include <stdlib.h>

int main()
{
   char ch;

   printf("Do you want to shutdown your computer now (y/n)\n");
   scanf("%c", &ch);

   if (ch == 'y' || ch == 'Y')
       system("C:\\WINDOWS\\System32\\shutdown -s");
       return 0;
}

For Windows 7

对于Windows 7

system("C:\\WINDOWS\\System32\\shutdown /s");

For Linux

system("shutdown -P now");
