1) 公开成员函数，调用最终导出类的成员函数
do_curr_symbol 。2) 返回此本地环境用作通货标识符的字符串。若
International （ std::moneypunct 的第二模板形参）为 false ，则此标识符通常为单个（宽）字符，例如 "￥" 或 "$" 。若 International 为 true ，则标识符通常为保有三个 ISO 4217 通货代码，后随空格的四字符字符串（ "JPY " 或 "USD " ）。返回值
保有通货符号或代码的 string_type 类型对象。
示例
运行此代码
#include <iostream> #include <locale> void show_ccy(const char* locname) { std::locale loc(locname); std::cout << locname << " currency symbol is " << std::use_facet<std::moneypunct<char, true>>(loc).curr_symbol() << "or " << std::use_facet<std::moneypunct<char>>(loc).curr_symbol() << " for short\n"; } int main() { show_ccy("en_US.utf8"); show_ccy("ja_JP.utf8"); show_ccy("sv_SE.utf8"); show_ccy("ru_RU.utf8"); show_ccy("vi_VN.utf8"); }
输出：
en_US.utf8 currency symbol is USD or $ for short ja_JP.utf8 currency symbol is JPY or ￥ for short sv_SE.utf8 currency symbol is SEK or kr for short ru_RU.utf8 currency symbol is RUB or руб for short vi_VN.utf8 currency symbol is VND or ₫ for short
