Lors de l'ex閏ution d'un programme C il y a trois zones de m閙oire
diff閞entes, correspondant aux trois dur閑s de vies possibles&nbsp;:
<DL COMPACT>
<DT><SMALL>-</SMALL>
<DD>la zone contenant les variables statiques&nbsp;;
<DT><SMALL>-</SMALL>
<DD>la zone contenant les variables automatiques
(cette zone est g閞閑 en pile puisqu'en C, toute fonction peut 阾re
r閏ursive)&nbsp;;
<DT><SMALL>-</SMALL>
<DD>la zone contenant les variables dynamiques
(cette zone est g閚閞alement appel閑 <I>le tas</I>).
</DL>
<P>
Un tel d閏oupage se rencontre couramment dans les langages de programmation.
G閚閞alement cependant, il n'est pas n閏essaire au programmeur de 
d閏larer la classe dans laquelle il d閟ire mettre une variable, cette
classe 閠ant choisie de mani鑢e autoritaire par le langage.
<P>
Les concepteurs du langage C ont voulu offrir plus de souplesse aux
programmeurs.
En effet, nous venons de voir que l'on pouvait mettre dans la classe des
variables statiques une variable qui 閠ait locale
