fall through v. (n. fallthrough, var. fall-through) 1. To exit a loop by exhaustion, i.e., by having fulfilled its exit condition rather than via a break or exception condition that exits from the middle of it. This usage appears to be really old, dating from the 1940s and 1950s. 2. To fail a test that would have passed control to a subroutine or some other distant portion of code. 3. In C, 'fall-through' occurs when the flow of execution in a switch statement reaches a case label other than by jumping there from the switch header, passing a point where one would normally expect to find a break. A trivial example: |

switch (color)
{
case GREEN:
do_green ( );
break;
case PINK:
do_pink ( );
/ * FALL THROUGH * /
case RED:
do_red ( );
break;

The effect of the above code is to do_green() when color is GREEN, do_red() when color is RED, do_blue() on any other color other than PINK, and (and this is the important part) do_pink() and then do_red() when color is PINK. Fall-through is considered harmful by some, though there are contexts (such as the coding of state machines) in which it is |
