Solved: Exercises 69 each contain a while loop annotated with a preand a post-condition
Chapter 5, Problem 9(choose chapter or problem)
Exercises 6–9 each contain a while loop annotated with a preand a post-condition and also a loop invariant. In each case, use the loop invariant theorem to prove the correctness of the loop with respect to the pre- and post-conditions.[Pre-condition: a = A and A is a positive integer.]while (a > 0)1. a := a ? 2end while[Post-condition: a = 0 if A is even and a = ?1 if A is odd.]loop invariant: I (n) is “Both a and A are even integers or both are odd integers and a ? ?1.”Unfortunately, we don't have that question answered yet.
