Question

Write a definition of a class named Point that can be used to store and manipulate the location of a point in the 2D plane. Provide a constructor to initialize the private data with default values. You will need to declare and implement the following member functions: A member function sec that vets the private data after an object of this class is created. A member function distance to find the distance of the point from the origin using the distance formula d = squareroot x^2 + y^2. A member function to swap the X and Y values. Two functions to retrieve the current coordinates of the point (one for X and Y). Write a test program that requests data for several points from the user, creates the points, then calls the member functions.

Explanation / Answer

Answer for Question:

1. Created class called Point with default and parametrized constructors.
2. Created set and distance and getX and getY methods
3. Created main method with two objects.

Code :

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

class Point
{
    // Coordinates x and y
    double x;
    double y;
public:
    // Default Constructor
    Point()
    {
        x = 0.0;
        y = 0.0;
    }
    // Parametrised Constructor
    Point(double x1, double y1)
    {
        x = x1;
        y = y1;
    }
    // Set method will set the x and y
    void set(double x1, double y1)
    {
        x = x1;
        y = y1;
    }
    // distance method will calculate the distance between origin and x,y
    double distance()
    {
        double result = 0.0;
        result = sqrt(x*x + y*y);
        return result;
    }
    // Swap the x and y
    void swap()
    {
        double temp;
        temp = x;
        x = y;
        y = temp;
    }
    // Retrieve methods for x and y
    double getX()
    {
        return x;
    }
    double getY()
    {
        return y;
    }
    // Print the x and y and distance
    void print()
    {
        cout<<"X is :"<<x<<" Y is :"<<y<<" Distance is :"<<distance()<<endl;
    }

};

int main()
{
    Point p1(5.6, 6.7), p2;
    p1.distance();
    p1.print();
    p2.set(7.8,9.45);
    p2.distance();
    p2.print();
    return 1;
}
