Given the following class, what is syntactically wrong with the implementation of the display function?
Class Rational
{
Public:
Rational);
Rationalint numer, int denom);
Rationalint whole);
Int getNumerator);
Int getDenominator);
Friend void displayostream& out, const Rational& value);
Private:

Given the following class, what is syntactically wrong with the implementation of the display function?
Class Rational
{

Rationalint numer, int denom);
Rationalint whole);
Int getNumerator);
Int getDenominator);
Friend void displayostream& out, const Rational& value);
Private:
Int numerator;
Int denominator;
};
Void displayostream& out, const Rational& value)
{
Out << value.getNumerator) << '/"<<value.getDenominator);
}
A) nothing
B) value must be not be pass by reference
C) The get functions are not const functions
D) out should be pass by value

Quizplus · Accepted Answer

The get functions should be declared as const functions since they do not modify the object's state. Therefore, the correct implementation of the class would be:
```
class Rational
{
public:
    Rational();
    Rational(int numer, int denom);
    Rational(int whole);
    int getNumerator() const;
    int getDenominator() const;
    friend void display(ostream& out, const Rational& value);
private:
    int numerator;
    int denominator;
};

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