05-11 Lab exercise 2: 3D points class inherited from 2D point class

Question

Suppose we have the following two points in a 3D space:

The distance between point1 and point2 is:

Please create ThreeD class inherited from Point class which is used in previous exercise and then use ThreeD class to calculate the distance between two 3D points.

Hint:

• Add two more public functions to Point class to get the value of X and Y
• ThreeD initialize: 

• class ThreeD:public Point

• The following constructor of ThreeD class reuses the constructor of the Point class and the only way values can be passed to the Point constructor is via the use of a member initialization list.

• ThreeD(double i, double j, double k):Point(i,j){z = k;}

   

Example input:

1 1 1
2 3 4

Example output:

Distance is: 3.74166

This is not correct answer. We require ThreeD class is inherited from Point class which is used in previous exercise
