Yes. (Actually, a good answer would be "sounds dangerous", because it is.)
When the test part of a
for is omitted it is
as if the value true were put in its place.
for ( initialize ; ; change ) loopBody ;
is the same as:
for ( initialize ; true ; change ) loopBody ;
This is done for compatibility with the language "C" and should not be done in newly written programs. In truth, it should never have been done in "C".
