NAME

std::moneypunct<CharT,International>::curr_symbol,do_curr_symbol - std::moneypunct<CharT,International>::curr_symbol,do_curr_symbol

Synopsis

Defined in header <locale>
public: (1)
string_type curr_symbol() const;
protected: (2)
virtual string_type do_curr_symbol() const;

1) Public member function, calls the member function do_curr_symbol of the most derived class.
2) Returns the string used as the currency identifier by this locale. If International (the second template parameter of std::moneypunct) is false, the identifier is usually a single (wide) character, such as "￥" or "$". If International is true, the identifier is usually a four-character string holding the three-character ISO_4217 currency code followed by a space ("JPY " or "USD ")

Return value

The object of type string_type holding the currency symbol or code.

Example

// Run this code

  #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");
  }

  ja_JP.utf8 currency symbol is JPY or ￥ for short
