CTEC3902 Rigorous Systems – De Montfort University

Section A – Theoretical Part

a) ¬P ∧ (fin P) ∧ skip3

b) skip2∧A = 2∧(A gets – A)

c) (skip ∧ fin(A=0)) ; (B=1 ∧ skip)

d) (P ∧ empty) ; skip ; skip2

e) A=1 ∧ (A gets A + 2) ∧ halt(A=7)

f) (len(2)∧”[]” (A=2) );(B=2∧B gets B – 1∧halt(B=0) )

g) len(4)∧(Q ;(skip⇒¬Q)*)
