Exercice<br />
On peut montrer :<br />
- {x = n ∧ n > 0} y := 1 {x = n ∧ n > 0 ∧ y = 1}<br />
- {x = n ∧ n > 0 ∧ y = 1}<br />
while not(x = 1) do y := y * x ; x := x - 1 od<br />
{y = n! ∧ n > 0}<br />
et conclure<br />
{x = n ∧ n > 0}<br />
y := 1 ; while not(x = 1) do y := y * x ; x := x - 1 od<br />
{y = n! ∧ n > 0}<br />
