how to break out of a FOR loop

[goju]

In my Visual C++ program, I click a button with the
mouse and a routine is executed. There is a FOR loop
in this routine which takes 30 seconds or longer to
complete. I would like to have the ability to exit
from this FOR loop before its normal completion by
hitting a key on the keyboard- preferably the "A"
key for abort.

include the <conio.h> head file and add the following statement into the for loop:

if (_kbhit() && (_getch() == 'A')) break;
