Incorrect Answer.
For the relation
par
T
if (x > 5) { y = x - 1;} else {y = x + 1;}
y > 3
to hold, it has to be the case that
at any state satisfying T ("true"), if the program in
question terminates, then the resulting store satisfies "y > 3".
This is not the case. For example, if we consider the initial store in which
the value stored in x equals 2, then the boolean guard "(x > 5)" of the
if-statement evaluates to "false", so the else-branch, "y = x + 1;" of
the if-statement gets executed, assigning to y the current value
stored in x plus one, that is 2 + 1, which is 3.
Thus, the program terminates in a state in which the value of y is not
greater than 3. This violates the claimed relationship above.
