Sure it is. In the statements

	c =3D 0;
	c =3D c++;

The increment can occur either before or after the assignment. You get
two different answers based on when it occurs.

	c++ evaluates to 0.=20

If the increment occurs, and then the assignment, 0 (the result of
evaluating c++) will be stored into c, over-writing the incremented
value.
If the assignment occurs first, then c will be assigned 0 and then the
increment will occur yielding 1 in c.

Two different outcomes from two different orders of evaluation.
