Create an exit function that has the system pause in it. Then,
everywhere you wish to exit, call the exit function. Only have to have
it in one place.

Yes, until you have a single exit in your program.
When you have more
possibilities you have to replicate the system("pause")
everywhere.

You can use "atexit" :
atexit()
Prototype: int atexit(void (_USERENTRY * func)(void));
Header File: stdlib.h
ANSI: C and C++
Explanation: Use atexit to have a function called when the program exits.
The parameter it accepts is a function name, without the typical () of a
function call. It must return void and accept no values (hence the use of
void in the prototype of atexit). If atexit is called more than once, the
last function passed to it will be the first one executed. It can be used up
to 32 times.
Example:
#include <iostream.h>
#include <stdlib.h>
//Program calls atexit with FinalFunction
//FinalFunction is executed before program ends
void FinalFunction(void)
{
cout<<"Final function called - Press enter to exit";
cin.get(); // or system("pause")
}
int main()
{
atexit(FinalFunction);
return 0;
}

How about the simplest solution of them all. Simply open a command prompt
yourself, go to your project directory, and execute your console program
from the command line. All those code workarounds are evil. Your "output
window" (console) closes because Dev-C++ simply launches the executable it
just compiled. Windows is responsible for the rest. In Windows, when a
console program has finished executing, its console is closed as well. This
is normal, standard behaviour, and has nothing to do with Dev-C++ (and
Dev-C++ isn't responsible for fixing this either). The solution to this
'problem' is to simply open a command prompt yourself (which you have to
close by yourself as well, will not be automatically closed), and execute
your program in there. Or has the Windows age alienated everyone from
anything having to do with command prompts?

Paul

Well, yes but there is a /K option to the DOS statement "command" that should keep the window open. I've just been, unsuccessfully, trying to figure a way to get it to recognize that option. Most anything can be done if you want it bad enough. Does that mean it's easy -- that it's worth doing -- that we'll ever figure it out :) ms At 09:05 AM 10/3/03, you wrote: >On Fri, Oct 03, 2003 at 03:43:28PM +0200, "P.D. van Zelst" ><pa...@my...> wrote: > > > How about the simplest solution of them all.

Perhaps instead of an exit function this might be simpler
int main()
{
functionToDoStuff();
system("pause");
return 0;
}

I suggested that alternative so that instead of explicitly exiting,
one could return from whereever in functionToDoStuff for the pause.
Though if there are many different functions that can exit, the use
of an exit function for the pause would be better.
However the 'atexit' suggested in another message sounds like
a cleaner solution.

I thought of another solution to the pause with multiple exits
problem using C++:
class PauseAtEnd
{ public:
~PauseAtEnd() { system("pause"); }
} myPause;
You can put it outside of a function or at the start of main().

Alternately, you can use getchar(), a portable, standard, etc. method of
leaving the input around until you press a key.
