here exists a data type Date with member function Increment that increments the current Date object by one. The ++ operator is being overloaded to postincrement an object of type Date. Select the correct implementation:

a. Date Date::operator++( int ) { Date temp = *this; Increment(); return *temp; } b. Date Date::operator++( int ) { Increment(); Date temp = *this; return temp; } c. Date Date::operator++( int ) { Date temp = *this; return this; temp.Increment(); } d. Date Date::operator++( int ) { Date temp = *this; Increment(); return temp; }
