C 標(biāo)準(zhǔn)庫(kù) - <locale.h>
C 庫(kù)函數(shù) struct lconv *localeconv(void) 設(shè)置或讀取地域化信息。它會(huì)返回一個(gè) lconv 結(jié)構(gòu)類(lèi)型的對(duì)象。
下面是 localeconv() 函數(shù)的聲明。
struct lconv *localeconv(void)
NA
該函數(shù)返回一個(gè)指向當(dāng)前區(qū)域 struct lconv 的指針，它的結(jié)構(gòu)如下：
typedef struct {
char *decimal_point;
char *thousands_sep;
char *grouping;
char *int_curr_symbol;
char *currency_symbol;
char *mon_decimal_point;
char *mon_thousands_sep;
char *mon_grouping;
char *positive_sign;
char *negative_sign;
char int_frac_digits;
char frac_digits;
char p_cs_precedes;
char p_sep_by_space;
char n_cs_precedes;
char n_sep_by_space;
char p_sign_posn;
char n_sign_posn;
} lconv下面的示例演示了 localeconv() 函數(shù)的用法。
#include <locale.h>
#include <stdio.h>
int main ()
{
struct lconv * lc;
setlocale(LC_MONETARY, "it_IT");
lc = localeconv();
printf("當(dāng)?shù)刎泿欧?hào): %s\n",lc->currency_symbol);
printf("國(guó)際貨幣符號(hào): %s\n",lc->int_curr_symbol);
setlocale(LC_MONETARY, "en_US");
lc = localeconv();
printf("當(dāng)?shù)刎泿欧?hào): %s\n",lc->currency_symbol);
printf("國(guó)際貨幣符號(hào): %s\n",lc->int_curr_symbol);
setlocale(LC_MONETARY, "en_GB");
lc = localeconv();
printf ("當(dāng)?shù)刎泿欧?hào): %s\n",lc->currency_symbol);
printf ("國(guó)際貨幣符號(hào): %s\n",lc->int_curr_symbol);
printf("小數(shù)點(diǎn) = %s\n", lc->decimal_point);
return 0;
}讓我們編譯并運(yùn)行上面的程序，這將產(chǎn)生以下結(jié)果：
當(dāng)?shù)刎泿欧?hào): EUR 國(guó)際貨幣符號(hào): EUR 當(dāng)?shù)刎泿欧?hào): $ 國(guó)際貨幣符號(hào): USD 當(dāng)?shù)刎泿欧?hào): ￡ 國(guó)際貨幣符號(hào): GBP 小數(shù)點(diǎn) = .
