Answer 1

there are application programming interface or "API" calls that can do that. Check out http://www.pscode.com for great sample codes.

Answer 2

hi,

There is a function called exec to execute external file from a C or C++ program. (Refer help document Turbo C/C++ Editor)
There is a windows command called shutdown to restart/shutdown the computer.
To know the details
type shutdown in your command prompt..

Restart -- exec("shutdown.exe","-r -t 100")
Shutdown -- exec("shutdown.exe","-s -t 100")

-t switch is optional specifies the time after which the computer will restart/shutdown

Answer 3

Assuming that you're running windows, he probably just called the ExitWindowsEx function included in windows.h

I'd be weary of running executables that a friend sends you unless you are compiling it yourself. This is how viruses can be spread. A rootkit only needs a restart to be implanted and they can come in small file sizes.

Answer 4

cout>>You'd have to pull apart the exe.

cout>>No such function

The prgm may shutdown your computer but there is no one function that will allow it.
