I am having a hard time understanding how to fix this code I get the error message that both point Point::x & Point::y are inaccessible. How do I fix this?

class Point {

    int x, y;

public:
    Point(int u, int v) : x(u), y(v) {} 
    int getX() { return x; }
    int getY() { return y; }

    void setX(int newX) { x = newX; } 
    void setY(int newY) { y= newY; } 

};
 
int main() {
    Point p(5, 3); 
    std::cout << p.x << ' ' << p.y;//should print out 5 3
    return 0;
}

The problem is that the data members x and y are private by default for a class type defined using the keyword class(as opposed to keyword struct).

To solve the error you can use the getters getX and getY as shown below:

 std::cout << p.getX() << ' ' << p.getY();

Demo.

Another option(less/not recommended) would be to make x and y public or use struct keyword but that would defeat the purpose of having getters and setters(setX and setY).

Class members (as opposed to struct members) are private by default so you can't directly access Point::x and Point::y outside of the definition of Point; however, you have defined getters for those values which are public.
