why can't I have any good friends?

My friend statments seem to be written wrong or something. Could someone look at these and see if they are written correctly?

Code:

---

friend ostream & operator << (ostream & o, const money m);
friend istream & operator >> (istream i, money m);

Thanks!

Leave the return values as references, the other things like riis said.

What errors do you get? Where did you put those declarations?

riis, thanks for the syntax. I should get a book that does a better job with classes. Still get the same errors.

cornedbee,

Here is the class declaration:

Code:

---

#ifndef MONEY_H
#define MONEY_H

#include <iostream>

class money
{
        protected:
                long int cents;
        public:
                money ();
                money (const money & m);
                money operator = (money m);
                long int getCents ();
                void setCents (long int l);

                bool operator < (money m);
                bool operator == (money m);
                void operator = (int i);
                money operator + (money m);
                money operator - (money m);
                money operator * (float f);
                money operator * (int i);

                friend ostream operator<< (const ostream &o, const money &m);
                friend istream operator>> (const istream &i, const money &m);

                //friend ostream & operator << (ostream & o, const money m);
                //friend istream & operator >> (istream i, money m);

};

#endif

And here are the friends in the cpp file

Code:

---

friend ostream operator<< (const ostream &o, const money &m);
//ostream & operator << (ostream & o, money m)
{
        o << (m.cents / 100) << '.';
        long int x = (m.cents % 100);
        if (x < 10)
                o << char (48);
        o << x;
        return o;
}

friend istream operator>> (const istream &i, const money &m);
//istream & operator >> (istream i, money m)
{
        float c;
        i >> c;
        m.cents = ((long int) ((c + 0.005) * 100.0));
        return i;
}

Try using friend std::ostream& ..., etc.

parksie, THANK YOU!
I can't believe I didn't have the using statements after iostream. I think I maybe relying on the forum too much. Anyway, thanks all of you for your help!

well as long as ur learning and not just getting HW answers :D
