C++. Inheritance relations in OOP. What corresponds to what?

Question

OOP

I am reading "The C++ Programming Language. Lectures and Exercises." — Prata.
It mentions (as far as I could see) five inheritance relationships:

1. is-a - is
   
2. has-a - contains
   
3. uses-a - uses
   
4. is-like-a - similar
   
5. is-implemented-as-a - implemented as
   

As far as I can understand:

• is-a corresponds to public inheritance
  
• has-a matches private inheritance or containment/composition
  
• uses-a matches using friend classes
  
• is-like-a matches protected inheritance
  
• is-implemented-as-a matches multiple inheritance
  

Correct if not. I didn't find anything on the net.

Answer 1

1. is-a - inheritance

class Car : public Vehicle {
 // автомобиль является транспортом
};

2. has-a - relation of type "composition"

class Car {
 Engine v8; // автомобиль имеет (содержит) двигатель
};

3. uses-a - relation of type "aggregation"

class Driver {
 Car* myCar; // водитель использует автомобиль
};

4. is-like-a

class Square : public Figure;
class Rectangle : public Figure;
// квадрат и прямоугольник похожи по свойствам, но это разные фигуры

5. is-implemented-as-a

class Engine { // абстракция
public:
 virtual void start() = 0;
protected:
 float power;
};

class V8 : public Engine { // реализация
 virtual void start() {
  // wroom wroom
 }
};

// Двигатель ДВС реализован как 8-ми цилиндровый двигатель V-конфигурации
