You cannot assume this. It will usually happen because you're
accessing clean memory, but it's entirely possible that you'll end up
with a value referenced to some previously-used memory. This is
particularly true when using local variables since they're stored on
the stack.

Can I assume declared but uninitialized variable to have the value

was used to
make those assumptions. I'm wondering whether it's the same for
Objective-C
/ C.
Thanks,
