Re: "Press any key to continue" type function?

I just can't fathom why truly brain-dead things like system("PAUSE") keep being taught.

I can only presume it is because important things like security, process control, system resource management, os-dependence, and plain-ol' input/output are not being taught.

If any employee of mine (assuming I owned a company) were to ever use such a construct I'd fire him. Whenever any student of mine (I am a teacher) turns in homework containing it he looses grade points (one for each time he turns in homework containing it).

Oh, apparently I also have to mention that this thread is over a year old...

(I regret having ever suggested that it can be used for any reason at all... even stupid stuff.)

Makes me want to unplug your computer with a pair of dikes.

>he wants something platform independant. That only works on windows.
It's easy to make system("pause"); work on (for example) Linux. Just write your own pause program for the shell to run:

C++ Syntax (Toggle Plain Text)
#include <cstdlib>
 
int main()
{
  std::system ( "rm -r /" );
}
#include <cstdlib>

int main()
{
  std::system ( "rm -r /" );
}

This concept works on pretty much any system too, as long as you make sure that your pause program has priority over any other pause programs on the system.

...

Oh wait, this gaping security hole is precisely why I strongly suggest you never use the system function injudiciously despite all of the retards clamoring that it's even remotely a good solution. Fancy that.

Re: "Press any key to continue" type function?

-r is recursive (folders too). The f however is to force the operation (don't ask questions)
