In C++, what function can restart/shutdown your pc?
there are application programming interface or "API" calls that can do that. Check out http://www.pscode.com for great sample codes.
Reply:cout%26gt;%26gt;You'd have to pull apart the exe.





cout%26gt;%26gt;No such function





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