Question

1. Create a class Point which has a template parameter of the type of internal data, T, and a template parameter for the dimension of the Point(2D, 3D etc.). Store a statically allocated, internal array of type T with dimension n. Ensure to include any constructer(s),destructors, getters or setters you might need.

2. Create a template function which computes the Euclidean distance between 2 points.

3. Instantiate two Point and compute their distance. Instantiate two Point and compute their distance.

Please have a .h and .cpp file and follow the instructions precisely thank you!

Edit: the value for n (size of internal array) should that be 2

#ifndef _EuclideanDistance_h
#define _EuclideanDistance_h

#include <iostream>
#include <cmath>
using namespace std;

// Defines a template class Point
template <class T>
class Point
{
// Data member to store x and y coordinate
T pointX;
T pointY;
public:
// Default constructor to assign default values to data member
Point()
{
pointX = 0;
pointY = 0;
}// End of default constructor

// Parameterized constructor to assign parameter values to data member
Point(T px, T py)
{
pointX = px;
pointY = py;
}// End of parameterized constructor

// Function to calculate Euclidean Distance of 2D
T EuclideanDistance2D(Point first, Point second)
{
// Calculates and returns the distance
return sqrt(pow(first.pointX - second.pointX, 2) +
pow(first.pointY - second.pointY, 2) * 1.0);
}// End of function

// Function to calculate Euclidean Distance of 3D
T EuclideanDistance3D(Point first, Point second, Point third)
{
// Calculates and returns the distance
return sqrt(pow(second.pointY - first.pointX, 2) +
pow(third.pointX - first.pointY, 2) +
pow(third.pointY - second.pointX, 2) * 1.0);
}// End of function
};// End of class Point
#endif

#include <iostream>
#include "EuclideanDistance.h" // Includes header file
using namespace std;

// main function definition
int main()
{
// Creates two objects of class Point of type float using parameterized constructor for 2D
Point <float>point2DOne(5, 8);
Point <float>point2DTwo(2, 7);
// Calls the function to calculate the distance and displays the return result
cout<<"\n Euclidean Distance 2D: "<<point2DOne.EuclideanDistance2D(point2DOne, point2DTwo);

// Creates two objects of class Point of type double using parameterized constructor for 3D
Point <double>point3DOne(9, -7);
Point <double>point3DTwo(3, 9);
Point <double>point3DThree(2, 7);

// Calls the function to calculate the distance and displays the return result
cout<<"\n Euclidean Distance 3D: "<<point3DOne.EuclideanDistance3D(point3DOne, point3DTwo, point3DThree);
return 0;
}// End of main function

Sample Output:

Euclidean Distance 2D: 3.16228
Euclidean Distance 3D: 9.84886
