Inheritance

// Base class

public:
    void sound() { cout << "..."; };
    // more methods
};

// Derived class 01
class Lion : public Mammal {

    void sound() { cout << "Grarrgraaagrgr\n"; };
    // more 🦁 methods
};

// Derived class 02
class Human : public Mammal {
public:
    void sound() { cout << "Let's code!\n"; };
    // more 👦 methods
};

// Derived class 03
class Sheep : public Mammal {
