No, u can't access "the first element".
reinterpret_cast won't change the pointer value, the result of reinterpret_cast "points to" the same object to which the argument of reinterpret_cast pointed to.
Indirection through such a pointer yields an lvalue denoting the object to which pointer points to and this influences lvalue-to-rvalue conversion applied to (or assignment through) this lvalue in a funny way.
