Homework

This week your task will be to modify the code from monday's session to work on n-dimensional data points.

   Clusterer-2D

Feel free to fork the repl.it and include a new class "PointND". The Class PointND should should be structured as shown in the following header file:

#ifndef PointN_H
#define PointN_H
#include <vector>
using namespace std;

class PointND {
    public:
        PointND(int dimensions); // constructor for zero point of n-dimensions

        PointND(vector<float> newND); // constructor for a point which copies the coordinates from an n-dimensional vector

        PointND operator+(PointND& p2);

        PointND operator/(float f);
       
        float getDim(int idx_dimension); // get the component of the indexed dimension, (this was getX() and getY() before)

        int size() // return how many dimension our current point has!
        {
            return _pointND.size();
        }
       
        void print();

        float getDistance(PointND&); // extend the euclidean distance to n dimensions

    private:
        vector<float> _pointND;
};
#endif

   Implement a PointND.cpp file that behaves like our class Point2D on n-dimensional points
   Test that class with a 3D distance measurement, and on success
   Modify our clusterer to work with the new PointND class!

Have fun and if you're stuck, write a mail or post a message in the forum!
