Question
Need help with this C++ Code:
#ifndef POINT3DWEIGHED_H_
#define POINT3DWEIGHED_H_
// TODO include iostream declarations but not definitions
#include "Point3D.h"
template<class T, class W>
class Point3DWeighed : public Point3D<T>
{
public:
// TODO Declare default constructor
// TODO Declare constructor from x, y, z, w
// TODO Declare copy constructor
// TODO Declare destructor
W getWeight() const;
void getPoint(T& x1, T& y1, T& z1, W& weight1) const;
// TODO Declare matching setWeight
// TODO Declare matching setPoint
// virtual T distanceToOrigin() const override; from Point3D
// TODO Declare friend operator+
protected:
W weight;
// TODO Declare protected functions below.
// TODO add
// TODO equals
// TODO less
// TODO print
// TODO read
// TODO Use keywords virtual, const, and override appropriately
};
#include "Point3DWeighed-impl.h"
#endif /* POINT3DWEIGHED_H_ */
#pragma once
Here's the Point3D.h which might be needed for above code.
Point 3D.h
#ifndef POINT3D_H_
#define POINT3D_H_
#include <iosfwd> // include iostream declarations but not definitions
#include "Point2D.h"
template<class T>
class Point3D : public Point2D<T>
{
public:
Point3D();
Point3D(T x, T y, T z);
Point3D(const Point3D& point);
virtual ~Point3D() override;
T getZ() const;
void getPoint(T& x1, T& y1, T& z1) const;
void setZ(const T z);
void setPoint(const T x1, const T y1, const T z1);
virtual T distanceToOrigin() const override;
template <class U>
friend Point3D<U> operator+(const Point3D<U>& p1, const Point3D<U>& p2);
protected:
T z;
virtual T multiply(const Point<T>& p1) const override;
virtual void add(const Point<T>& p1) override;
virtual bool equals(const Point<T>& p1) const override;
virtual bool less(const Point<T>& p1) const override;

virtual void read(std::istream& is) override;
};
