why can't I have any good friends?

[NOMADMAN]

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

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?

[NOMADMAN]

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:

#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

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:stream& ..., etc.

[NOMADMAN]

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!
