Question

You are given this class definition:

class Rectangle{
private:
    double side1, side2;    // Side lengths
public:
    Rectangle();    // Default constructor, set side lengths = 0
    Rectangle(double s1, double s2);    // Overloaded constructor
                                        // Set side lengths = s1 and s2
    void setSide(double s1, double s2); // Change side lengths to s1 & s2
    double area();  // Calculate the area of the rectangular
    double perimeter(); // Calculate the perimeter of the rectangular
    double diagonal();  // Calculate the length of the diagonal
    bool isSquare();    // Check if the rectangle is a square
};

Please complete this class.
