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++?
Basically, what is the code to turn off a windows xp computer in c++?

On windows you can use the ExitWindows function described here:

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

You can do this in Windows, by calling the ExitWindowsEx
function.
Use the following, assuming you have the privileges):
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).
It's part of the Win32 API rather than standard C++ but that's because C++ provides no way to do this directly.
You can shutdown by utilizing the system() function.
for Windows
system("shutdown -s");
for Linux
system("poweroff");
or
system("init 0");
