class Shape {
public:
  virtual ~Shape() = default; // virtual destructor

  virtual void draw() const = 0; // pure virtual function
};

class Circle : public Shape {
public:
  void draw() const override {
    // draw circle
  }
};

int main() {
  Shape* pShape = new Circle;
  delete pShape; // calls Circle destructor
  return 0;
}

y declaring a virtual destructor for your abstract classes in C++, you can ensure that objects of derived classes are properly destroyed when they are deleted, avoiding memory leaks and other issues.
