The assignment expression statement 
    a = 0;
implies that there is an object named (a)
and that after the assignment 
that (a) will have a value of (0).

The assignment expression (a = 0) 
does *not* imply that prior to the assignment
that there is a region of storage with a value of (0)
waiting to be loaded and moved into (a).
