Does dereferencing a volatile pointer produce a volatile element?

as far as I understand volatile this is just telling
the compiler that the assignment here can not be reordered
thats it - it does not change the propertieis of a[] in any
way if that is what you means with "produce volatile elements"
with other words if you later use say a[4] = c (with c not
being volatile) then the compiler can again reorder / optimize
out things as seen fit.
