fall through (programming)(The American misspelling "fall thru" isalso common)
1. To exit a loop by exhaustion, i.e. by having fulfilled itsexit condition rather than via a break or exception conditionthat 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 asubroutine or some other distant portion of code.
3. In C, "fall-through" occurs when the flow of execution in aswitch statement reaches a "case" label other than byjumping there from the switch header, passing a point whereone would normally expect to find a "break". A trivialexample:
switch (colour)case GREEN: do_green
The effect of the above code is to "do_green()" when colour is"GREEN", "do_red()" when colour is "RED", "do_blue()" on anyother colour other than "PINK", and (and this is the importantpart) "do_pink()" __and then__ "do_red()" when colour is "PINK".Fall-through is considered harmful by some, though there arecontexts (such as the coding of state machines) in which it isnatural; it is generally considered good practice to include acomment highlighting the fall-through where one would normallyexpect a break.
