Hello everyone,

I am C++ beginner and I have a basic questions regarding classes

Referring to the code below, I am trying to access x and y from the coordinate class in method abc after having run the place method.

I hope this is clear

Here is my code:

```
class coordinate
{
friend class closedcurve;
public:
coordinate() {}
coordinate(double xin,double yin) {x=xin;y=yin;}
double x;
double y;
double getx() { return x; }
double gety() { return y; }
friend void place(double a);
};
class circle
{
public:
circle(double a);
~circle();
double area();
double circumference();
coordinate place(double a);
};
coordinate square::place(double a)
{
... some code
return coordinate(xa,xb);
}
void square::abc(double b)
{
place(b);
how do i access x and y from the coordinate class in here??
}
```
