From cppreference.com
< cpp‎ | locale‎ | moneypunct

Defined in header `<locale>` |  |
public: char_type thousands_sep() const; | (1) |
protected: virtual char_type do_thousands_sep() const; | (2) |

1) Public member function, calls the member function `do_thousands_sep` of the most derived class.
2) Returns the character to be used as the separator between digit groups when parsing or formatting the integral parts of monetary values.

### [edit] Return value

The object of type `char_type` to use as the thousands separator. In common U.S. locales, this is ’,’ or L’,’.

### [edit] Example

Run this code

    #include <locale>
    #include <iostream>
    #include <iomanip>
    #include <iterator>
    struct space_out : std::moneypunct<char> {
        pattern do_pos_format()      const { return { {value, none, none, none} };}
        int do_frac_digits()         const { return 0; }
        char_type do_thousands_sep() const { return ' ';}
        string_type do_grouping()    const { return "\002";}
    };
    int main()
    {
        std::cout.imbue(std::locale("en_US.UTF-8"));
        std::cout << "american locale: " << std::showbase
                  << std::put_money(12345678.0)<< '\n';

        std::cout.imbue(std::locale(std::cout.getloc(), new space_out));
        std::cout << "locale with modified moneypunct: "
                  << std::put_money(12345678.0)<< '\n';
    }

Output:

    american locale: $123,456.78
    locale with modified moneypunct: 12 34 56 78
