In practice, I expect that most C programmers probably

C Standard may not entitle them to that assumption, but they
assume it anyway.  Part of this is the Java influence no

That's an interesting point, I suspect it is indeed the
case that more C programmers will assume that C matches Java
semantics (indeed in a sense Java derived its semantics
from C practice).
