Il est possible d'utiliser l'op閞ateur de soustraction pour calculer la
diff閞ence de deux pointeurs. Cela n'a de sens que si les deux pointeurs
rep鑢ent des 閘閙ents d'un m阭e tableau.
<P>
Soient p1 et p2 deux pointeurs du m阭e type tels que p1 rep鑢e le i<SUP><I>eme</I></SUP>
閘閙ent d'un tableau, et p2 rep鑢e le j<SUP><I>eme</I></SUP> 閘閙ent du m阭e tableau,
p2 - p1 <B>est une valeur de type <code>ptrdiff_t</code></B> qui est 間ale
