\ud83d\udccc En C ANSI, les tailles exactes d\u00e9pendent de la machine et du compilateur<\/strong>, mais il existe des tailles minimales garanties<\/strong>.<\/p>\n<\/blockquote>\n\n\n\n

\ud83e\uddee Macros utiles (<limits.h><\/code>)<\/h2>\n\n\n\n

Tu peux conna\u00eetre les valeurs limites exactes<\/strong> via ces macros :<\/p>\n\n\n\n

#include <limits.h>

printf(\"INT_MAX = %d\\n\", INT_MAX);
printf(\"INT_MIN = %d\\n\", INT_MIN);
printf(\"UINT_MAX = %u\\n\", UINT_MAX);
printf(\"LONG_MAX = %ld\\n\", LONG_MAX);
printf(\"CHAR_BIT = %d\\n\", CHAR_BIT); \/\/ nombre de bits dans un char
