Trouble with overloading Insertion Operator

Hey. I'm coding an abstract data type for a rational number. I have been attempting to code the operator overload for insertion, but when doing so i recieve errors telling me that the objects members are private (and thus, cannot be accessed) despite it being a friend function. If someone may have any ideas about what may be wrong here, I would of course appreciate it :)

##FUNCTION DEFINITION FOR OVERLOAD##

Code:

---

ostream& operator <<(ofstream& outs, const rational& temp){
        if (!temp.positive)
        outs << "-";
        outs << temp.ratNum[0] << "/" << temp.ratNum[1];
        return outs;
}

---

##HEADER FILE W/ CLASS DEFINITION##

Code:

---

#include <iostream>
#include <fstream>

using namespace std;
const int size = 2;
class rational{

        friend rational operator+(const rational&, const rational&);
        friend rational operator-(const rational&, const rational&);
        friend rational operator*(const rational&, const rational&);
        friend rational operator/(const rational&, const rational&);
        void friend subtractRational(rational&, rational&, rational&);
        void friend addRational(rational&, rational&, rational&);
        void friend multRational(rational, rational, rational&);
        void friend divRational(rational, rational, rational&);
        void friend lcd (rational&, rational&);
        void friend gcf(rational&);
        friend ostream& operator<<(ostream&, const rational&);
        friend istream& operator>>(istream&, const rational&);

public:
        void output();
        rational operator =(const rational&);
        rational(int);
        rational(void);                                        // void constructor
        rational(int, int);        // constructor for creating rational number
        ~rational();                                // destructor
        rational(const rational&);

private:
        int *ratNum;
        bool positive;
};

The signature says:

Code:

---

friend istream& operator>>(istream&, const rational&);

---

Surely you want to modify the object you are inputting to?

Another problem with operator<<:

Code:

---

//friend declaration:
friend ostream& operator<<(ostream&, const rational&);

//implementation
ostream& operator <<(ofstream& outs, const rational& temp) {...}

---

Naturally that function isn't a friend of rational.

I also hope ratNum, which is an array of two integers (?), is not going to be dynamically allocated?

edit: thanks a lot :) was able to make a lot of progress due to the things you pointed out. Please forgive my lack of complete understanding of this subject - I am enrolled in a course where we will be studying these things in the future, but I am looking ahead at future material due to eagerness.
