Method 1: Private copy constructor and copy assignment operator
class Car {
public:
Car(): owner() {}
void setOwner(Person *o) { owner = o; }
Person *getOwner() const { return owner; }
void info() const;
private:
Car(const Car&);
Car& operator=(const Car&);
Person *owner;
};
Method 2: Deleted copy constructor and copy assignment operator
class Car {
public:
Car(const Car&) = delete;
void operator=(const Car&) = delete;
Car(): owner() {}
void setOwner(Person *o) { owner = o; }
Person *getOwner() const { return owner; }
