The facet std::moneypunct encapsulates monetary value format preferences. Stream I/O manipulators std::get_money and std::put_money use std::moneypunct through std::money_get and std::money_put for parsing monetary value input and formatting monetary value output.

Example

Run this code
#include <iostream>
#include <locale>
int main()
{
    std::locale jp("ja_JP.UTF-8");
    std::cout << "japanese currency symbol is "
              << std::use_facet<std::moneypunct<char, true>>(jp).curr_symbol()
              << "or "
              << std::use_facet<std::moneypunct<char>>(jp).curr_symbol()
              << " for short\n";
}

Output: 

japanese currency symbol is JPY or ￥ for short
