Whenever I deal with characters I always write foo[n] = '\0'; it's
three more character to type sure. But it's also documentation of what
I'm doing with the variable foo, it shows that it's a string/char
operation.

Yeah, I agree that it makes things explicit, and I don't mind typing
the extra 3 characters. But I guess to me it boils down to a judgment
call. Does the context already make it clear enough? If so, then
I might go with a bare 0 just because it is less cluttered. To me,
clutter makes things harder to read, so being explicit about things
has to be balanced against that.

Also, I don't think it's necessarily bad to use type coercion. For
instance, is this code unclear?

float f = 0.0;

The 0.0 is of type double and is coerced to a float, but I don't
have any problem at all reading that and understanding what it would
do, even though this would be more explicit:

float f = 0.0F;
