Write a Point class that represents a 2-d point in a plane. Write member functions to a. Set and show the value of a point b. Find the distance between two points c. Check whether two points are equal or not

SOURCE CODE:

#include <iostream>

#include <cmath>

using namespace std;

class Point {

private:

    double x, y;

public:

    // Constructor

    Point(double x = 0, double y = 0) : x(x), y(y) {}

    // Set the value of the point

    void setPoint(double x, double y) {

        this->x = x;

        this->y = y;

    }

    // Show the value of the point

    void showPoint() const {

        cout << "Point(" << x << ", " << y << ")" << std::endl;

    }

    // Find the distance between two points

    double distanceTo(const Point &other) const {

        return sqrt(std::pow(x - other.x, 2) + std::pow(y - other.y, 2));

    }

    // Check whether two points are equal or not

    bool equals(const Point &other) const {

        return x == other.x && y == other.y;

    }

};

int main() {

    Point p1(1, 2);

    Point p2(4, 6);

    p1.showPoint();

    p2.showPoint();

    cout << "Distance between points: " << p1.distanceTo(p2) << std::endl;

    cout << "Points are equal: " << (p1.equals(p2) ? "Yes" : "No") << std::endl;

    return 0;

}

OUTPUT:

Point(1, 2)

Point(4, 6)

Distance between points: 5

Points are equal: No
