# std::money_put

< cpp‎ | locale

Defined in header `<locale>` |  |
template< class CharT, class OutputIt = std::ostreambuf_iterator<CharT> > class money_put; |  |

Class `std::money_put` encapsulates the rules for formatting monetary values as strings. The standard I/O manipulator std::put_money uses the `std::money_put` facet of the I/O stream's locale.

Inheritance diagram

### Type requirements

- `OutputIt` must meet the requirements of LegacyOutputIterator.

### Specializations

Two standalone (locale-independent) full specializations and two partial specializations are provided by the standard library:

Defined in header `<locale>`
std::money_put<char> | creates narrow string representations of monetary values
std::money_put<wchar_t> | creates wide string representations of monetary values
std::money_put<char, OutputIt> | creates narrow string representations of monetary values using custom output iterator
std::money_put<wchar_t, OutputIt> | creates wide string representations of monetary values using custom output iterator

In addition, every locale object constructed in a C++ program implements its own (locale-specific) versions of these specializations.

### Member types

Member type | Definition
`char_type` | `CharT`
`string_type` | `std::basic_string<CharT>`
`iter_type` | `OutputIt`

### Member functions

(constructor) | constructs a new money_put facet (public member function)
(destructor) | destructs a money_put facet (protected member function)
put | invokes `do_put` (public member function)

### Protected member functions

do_put [virtual] | formats a monetary value and writes to output stream (virtual protected member function)

### Member objects

static std::locale::id id | id of the locale (public member object)

### Example

Run this code

    #include <iostream>
    #include <locale>
    #include <iomanip>
    #include <iterator>
    int main()
    {
        // using the IO manipulator
        std::cout.imbue(std::locale("en_US.UTF-8"));
        std::cout << "american locale: "
                   << std::showbase << std::put_money(12345678.9)<< '\n';

        // using the facet directly
        std::cout.imbue(std::locale("de_DE.UTF-8"));
        std::cout << "german locale: " ;
        auto& f = std::use_facet<std::money_put<char>>(std::cout.getloc());
        f.put({std::cout}, false, std::cout, std::cout.fill(), 12345678.9 );
        std::cout << '\n';
    }

Output:

    american locale: $123,456.79
    german locale: 123.456,79 €
