Class

Object Oriented Programming System (OOPs) is a programming model built on the perception of “objects” that contains data and methods. The major purpose of Object Oriented Programming is to increase the maintainability and flexibility of programs. Object Oriented Programming gets together data and its behavior (methods) in a single location (object) which makes it easier to understand.

Question

H.W: Modify class Point to represent points in 3D instead of 2D.

#include <iostream>
using namespace std;
// class declaration section
class Point
{
private:
double x;
double y;
public:
Point (double idx = 0.0, double idy = 0.0)
// constructor
x = idx;
y = idy;
void show ()
{
cout << "The x coordinate is: " << x << ", The y coordinate is: " << y
<< endl;
};
int main ()
{
Point *ptrPoint;
// declares Point pointer
Point point1 (4, 6);
// creates Point object
Point point2 (8, 9);
// creates Point object
cout << "The coordinates of Point1 is: ";
ptrPoint = &point1;
ptrPoint->show ();
cout << "The coordinates of Point2 is: ";
ptrPoint = &point2;
ptrPoint->show ();
return 0;
Microsoft Visual Studio Debug Console
The coordinates of Point1 is: The x coordinate is: 4, The y coordinate is: 6
The coordinates of Point2 is: The x coordinate is: 8, The y coordinate is: 9
