Thank you.

Here is a simple example of a point class. Let us know if you have any further questions.

#include <iostream>

using namespace std;

class cartesianCoordinates {

private:
    int x;
    int y;
public:
    // constructor using initializer list 
    cartesianCoordinates(int x, int y) : x(x), y(y) {}


    int getX() const {
        return x;
    }

    void setX(int x) {
        cartesianCoordinates::x = x;
    }

    int getY() const {
        return y;
    }

    void setY(int y) {
        cartesianCoordinates::y = y;
    }

    friend ostream &operator<<(ostream &os, const cartesianCoordinates &coordinates);

};

ostream &operator<<(ostream &os, const cartesianCoordinates &coordinates) {
    os << "(" << coordinates.x << "," << coordinates.y << ")";
    return os;
}


int main() {

    // declaring a point
    cartesianCoordinates aPoint(1, 2);

    // printing a point using overloaded << operator  
    cout << aPoint;

    return 0;
}

(1,2)

Process finished with exit code 0
