Accessing variables in nested classes - c++

Question

I've nested a class for use within another class and need to try accessing individual parts of it but can't. How would I go about doing this?
class Point
{
public:
Point() { float x = 0, y = 0; }
void Input(int &count); //input values
Rectangle myRec;
private:
float x, y;
};
class Rectangle
{
public:
Rectangle(); //side1 - horizontal, side2 - vertical
void SetPoint(const Point point1, const Point point2, const Point point3, const Point point4) { LLPoint = point1; LRPoint = point2; URPoint = point3; ULPoint = point4; }
float CalcSides(Point LL, Point LR, Point UL, Point UR);
private:
Point LLPoint, LRPoint, ULPoint, URPoint;
float side1, side2, length, width, area, perimeter; //side1 - horizontal, side2 - vertical
};
float Rectangle::CalcSides(Point LL, Point LR, Point UL, Point UR)
{
side1 = (LR.x - LL.x);
}
How can I access the x and y values for the points I've created in the Rectangle class?

Answer 1

If you really want to do this, then you can make the classes friends.
class Rectangle;
class Point
{
friend class Rectangle;
public:
Point() { x = 0; y = 0; }
void Input(int &count); //input values
private:
float x, y;
};
More likely though, you simply want to add accessors to the Point class as it is fairly useless as is.
class Point
{
public:
Point() { x = 0; y = 0; }
void Input(int &count); //input values
float getX() const { return x; }
float getY() const { return y; }
private:
float x, y;
};
Or, if Point is really going to be so simple and not need to maintain any invariants at all, just expose x and y as public members.
Also, you probably don't want to have Point contain a Rectangle but rather refer to one either through a pointer or a reference, if it refers to one at all. After all, a Point can be useful without reference to a Rectangle (e.g. - maybe it's used for Triangles too).
