# std::moneypunct::curr_symbol, do_curr_symbol

From cppreference.com
< cpp‎ | locale‎ | moneypunct

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

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 international currency code followed by a space ("JPY " or "USD ")

### [edit] Return value

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

### [edit] 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");
    }
