Is it possible to exit a C++ loop based on keyboard input without actually having to input something each iteration?
For instance
while(checkkeyboardinput != 'q')
{
do work
}
I feel that this is very easy, but google isn't helping me, and I can't remember how to do this. Thanks for the help.
EDIT: I'm using VS2008
Try _kbhit(). As far as I know it checks if there is any keyboard input waiting in the buffer.

_kbhit
Checks the console for keyboard input.
int _kbhit( void );
Return Value
_kbhit returns a nonzero value if a key has been pressed. Otherwise, it returns 0.
Remarks
The _kbhit function checks the console for a recent keystroke. If the function returns a nonzero value, a keystroke is waiting in the buffer. The program can then call _getch or _getche to get the keystroke.
If you are using ncurses, you can, very easily, with getch(). However, there is not standard way to do what you want.
You neglected to mention what OS you're running. Getting keyboard input is OS dependent (even library dependent -- eg. how to do it with GTK is obviously GTK specific.)
Well, GTK runs on multiple OS'es, so... but you get the idea. You need to specify a bit more about the environment your working in to get a reasonable answer.
