Question

How do I return a point object aggregated in a another class? I’m trying to return a point object that’s a private member of the quad class. I have written the function and it compiles, but I don’t know the correct syntax to call that function.

Point Quad::getA()
{
    return Point a;
}


 void Quad::check()
 {
    cout << this->getA();  //will not work
 }

Answer 1

This will work:

class Quad {
  Point a;
  Point getA();
  void check();
};

Point Quad::getA()
{
    return a;
    // or: return Point(); 
    // to return a new point
}

void Quad::check()
{
    cout << getA(); // requires << be overloaded
    // perhaps this is what you want:
    // cout << getA().x;

}
