Expert's answer
#include <iostream>

using namespace std;

class Shape
char unused;

int x, y;

string name;

void SetPosition(int x, int y)
this->x = x;
this->y = y;

/* Using 'protected' inheritance specifier.
Public and protected members of the parent class become protected.
Private members stay private */
class Rectangle : protected Shape
void SetName(string name)
/* The child class has access
to the public fields of the parent class */
this->name = name;

void Move(int delta_x, int delta_y)
/* We have also access to the protected fields of the parent class */
this->x += delta_x;
this->y += delta_y;

//this->unused = '$'; //this is wrong

void main()
Rectangle rect;

/* The line below causes compilation error
because SetPosition is a protected method */
//rect.SetPosition(2, 4);
rect.Move(8, -3);
