C - We introduced a general rule for the operation of reading from a pointer: {x => v} y = *x; {x => v && y = v} (We write "&&" where a different logical "and" operator appears in the slides.) The rule requires some important side conditions.


Assuming that x, y, and v are distinct program variables, which of the following expressions for v would lead to a wrong conclusion by the rule as given, without side conditions? (Such a case must necessarily be violating the side conditions!)

·       x

·       y

·       x+1

·       y+1
