Re: [Dev-C++] Getting the wrong output

[jalkadir gosonic ca]

Yes, I just notice that, so this are the changes I have made:

--- Money.hpp
friend std::ostream& std::operator<<( std::ostream&, const jme::Money& );
friend std::istream& std::operator>>( std::istream&, jme::Money& );


--- Money.cpp
std::operator<<( std::ostream& os, const jme::Money& obj ) {
    os << obj.getAmount();
    return os;
}
std::istream&
std::operator>>( std::istream& is, jme::Money& obj ) {
    is >> obj.amount;
    return is;
}
--------------
But this is giving me linker errors sayng:


=========  ERROR ===========
In file included from money.cpp:2:
money.hpp:67: error: `std::ostream& std::operator<<(std::ostream&, const
jme::Money&)' should have been declared inside `std'
money.hpp:68: error: `std::istream& std::operator>>(std::istream&,
jme::Money&)' should have been declared inside `std'


What am I doing wrong!!?

Again thanks for you help.
