Step 1 of 8

Inheritance

A class can inherit from another, getting all its members, then add or change behaviour:

class Weapon {
public:
    int damage = 10;
    void describe() const { std::cout << damage << "\n"; }
};

class Rifle : public Weapon {    // a Rifle IS-A Weapon
public:
    int magazine = 30;
};

Rifle r;
r.damage = 36;      // inherited
r.describe();       // inherited

Your turn: make Sniper inherit from Weapon and set the base part through the base constructor.

Next: virtual and override
