Question

Must be C++ programming
   The MyPoint class was created to model a point in a two-dimensional space. The MyPoint class has the properties x and y that represent x- and y-coordinates, two get functions for x and y, and the function for returning the distance between two points. Create a class named ThreeDPoint to model a point in a three-dimensional space. Let ThreeDPoint be derived from MyPoint with the following additional features:
A data field named z that represents the z-coordinate.
A no-arg constructor that constructs a point with coordinates(0,0,0).
A constructor that constructs a point with three specified coordinates.
A constant get function that returns the z value.
A constant distance(const ThreeDPoint&) function to return the distance between this point and the other point in the three-dimensional space.
    Implement the classes. Write a test program that creates two points (0,0,0) and (10,30,25.5) and displays the distance between them.

Here is the answer for your question in C++ Programming Language.

CODE :

#include<iostream> #include<cmath> #include<iomanip> using namespace std; //MyPoint Class class MyPoint{    public:        //Class member variables        double x;        double y;        //Default constructor that sets point(0,0)        MyPoint(){            x = 0;            y = 0;        }        //Parameterised constructor that creates a point with specified co-ordinates        MyPoint(double X,double Y){            x = X;            y = Y;        }        //Returns x        double getX(){   return x; }        //Returns y        double getY(){ return y;   }        //Returns ditance between two points        double distance(const MyPoint& p1) const{            return sqrt(((p1.x - x)*(p1.x - x)) + ((p1.y - y)*(p1.y - y)));        } }; class ThreeDPoint : public MyPoint{    //Class variable    double z;    public:        //Default constructor that sets point(0,0,0)        ThreeDPoint(){        z = 0;                  }        //Parameterised constructor that creates a point with specified co-ordinates        ThreeDPoint(double X, double Y, double Z) : MyPoint(X,Y){            z = Z;        }        //Returns z        double getZ() const{ return z; }        //Returns ditance between two points        double distance(const ThreeDPoint& p1) const{                      return sqrt(((p1.x - x)*(p1.x - x)) + ((p1.y - y)*(p1.y - y)) + ((p1.z - z)*(p1.z - z)));        }        }; int main(){       //Creates two points p1 and p2    ThreeDPoint p1;    ThreeDPoint p2(10,30,25.5);       //Display output    cout << "First point (" << p1.getX() << ", " << p1.getY() << ", " << p1.getZ() << ") is created." << endl;    cout << "Second point (" << p2.getX() << ", " << p2.getY() << ", " << p2.getZ() << ") is created." << endl;       cout << "Distance between the two points : " << fixed << setprecision(2) << p1.distance(p2) << endl;    return 0; }
