template<class MoneyT> /*unspecified*/ get_money( MoneyT& mon,bool intl=false); | (since C++11) | |
When used in an expressionin>> get_money(mon, intl), parses the character input as a monetary value, as specified by thestd::money_get facet of the locale currently imbued inin, and stores the value inmon.
The extraction operation inin>> get_money(mon, intl) behaves as aFormattedInputFunction.

| mon | - | variable where monetary value will be written. Can be eitherlongdouble orstd::basic_string |
| intl | - | expects to find required international currency strings iftrue, expects optional currency symbols otherwise |
An object of unspecified type such that
where the functionf is defined as:

Output:
