Le minimum \u00e0 connaitre de cette fonction <\/h2>\n\n\n\n
%i<\/strong> et %d<\/strong>  affiche en d\u00e9cimal<\/p>\n\n\n\n
%o<\/strong> affiche en octal<\/p>\n\n\n\n
%x<\/strong> affiche en hexad\u00e9cimal<\/p>\n\n\n\n
La fonction printf permet aussi ce genre de choses:<\/p>\n\n\n\n
printf(\u00ab\u00a0%02d\u00a0\u00bb, 1);<\/p>\n\n\n\n
donnera <\/p>\n\n\n\n
01<\/p>\n\n\n\n
printf<\/strong>(\u00ab\u00a0%02x\u00a0\u00bb, 15);<\/p>\n\n\n\n
donnera <\/strong><\/p>\n\n\n\n

Exemple d’un affichage d’une cha\u00eene de caract\u00e8re (string) :<\/h2>\n\n\n\n
printf (\u00a0\u00bb Bonjour le monde \\n\u00a0\u00bb);<\/strong><\/p>\n\n\n\n
On passe la cha\u00eene \u00e0 afficher ici Bonjour le monde \\n<\/p>\n\n\n\n
on peut ici noter que \\n  (lire anti slash n)  va nous provoquer l’affichage d’un code de contr\u00f4le  (caract\u00e8re 10) qui va faire passer \u00e0 la ligne suivante.<\/p>\n\n\n\n
Exemple d’un affichage d’une cha\u00eene ou int\u00e8gre une valeur en d\u00e9cimale:<\/h2>\n\n\n\n
printf (\u00a0\u00bb Bonjour le monde en %d \\n\u00a0\u00bb,2025);<\/strong><\/p>\n\n\n\n
