That's what the standard says it has to be. But since "if the initial
evaluation of the condition is false" can be tested before getting to the
while test, it is trivial to deal with this, and usually, deal with it
more elegantly than having some magic exit value from a while where the
body is never executed.
But like Lawrence, I'm not at all sure that is what Budi actually wants.
