    char *setlocale(int type, const char *locale);

   #include <locale.h>
   int main ()
     { 
        struct lconv * st;
        st=localeconv();	
        printf ("Locale is: %s\n", setlocale(LC_ALL,NULL) );
        printf ("Currency symbol is: %s\n-\n",st->currency_symbol,
               setlocale (LC_ALL,"French") );
