setlocale()函数测试当前语言的两个程序
http://www.cnblogs.com/cnyao/archive/2010/05/06/1729220.html
setlocale()函数是用来配置地域信息的,原本以为这个也是windows函数,结果居然是C++的标准函数,其头文件为<clocale>,按照一般的原则,所有原本C的函数被移植到C++标准库中时,是按照去掉后面的.h,前面加上c这样的原则。举例:<stdio.h>变成<cstdio>,所以我猜<clocale>也是这样,但是没有继续去确认。(从示例2上看,猜想是正确的)
测试程序1:
#include <stdio.h>
#include <clocale>
using namespace std;
void
sr_set_locale (void)
{
setlocale (LC_ALL, "");
setlocale (LC_CTYPE, "");
printf ("LOCALE is %s\n",setlocale(LC_ALL,NULL));
}
int main()
{
sr_set_locale();
return 0;
}
根据你系统地域设置的不同,你得到的结果也不同,我这里运行得到的结果为:
LOCALE is Chinese_People's Republic of China.936
测试程序2:
/* setlocale example */
#include <stdio.h>
#include <time.h>
#include <locale.h>
int main ()
{
time_t rawtime;
struct tm * timeinfo;
char buffer [80];
struct lconv * lc;
time ( &rawtime );
timeinfo = localtime ( &rawtime );
int twice=0;
do {
printf ("Locale is: %s\n", setlocale(LC_ALL,NULL) );
strftime (buffer,80,"%c",timeinfo);
printf ("Date is: %s\n",buffer);
lc = localeconv ();
printf ("Currency symbol is: %s\n-\n",lc->currency_symbol);
setlocale (LC_ALL,"");
} while (!twice++);
return 0;
}
输出结果为:
Locale is: C Date is: 05/06/10 20:51:14 Currency symbol is: - Locale is: Chinese_People's Republic of China.936 Date is: 2010-5-6 20:51:14 Currency symbol is: ¥ -
