{
public:

Rational(int whole);

int getNumerator();
int getDenominator();

friend void display(ostream& out, const Rational& value);
private:
int numerator;
int denominator;
};

void display(ostream& out, const Rational& value)
{
out << value.getNumerator() << '/"< }

b. value must be not be pass by reference
c. The get functions are not const functions
