Member functions
moneypunct::curr_symbolmoneypunct::do_curr_symbol
Defined in header
<locale>
public:
string_type curr_symbol() const;
(1)
string_type curr_symbol() const;
protected:
virtual string_type do_curr_symbol() const;
(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 ").[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"); }
Output:
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
[edit] Defect reports
The following behavior-changing defect reports were applied retroactively to previously published C++ standards.
| DR | Applied to | Behavior as published | Correct behavior |
|---|---|---|---|
| LWG 666 | C++98 | the length of the identifier string was required to be 4 if International is true

not required |
