Inheritance

Inheritance allows a class (derived) to acquire members of another class (base). Use the colon syntax with an access specifier: class Derived : public Base.

Access Specifiers in Inheritance

public — public members stay public, protected stay protected.
protected — public and protected become protected in the derived class.
private — public and protected become private in the derived class.

#include <iostream>
using namespace std;

class Vehicle {
public:
  string brand = "Ford";

  void honk() {
    cout << "Beep beep!\n";
  }
};

class Car : public Vehicle {
public:
  string model = "Mustang";
};

int main() {
  Car car;
  car.honk();
  cout << car.brand << " " << car.model << "\n";
  return 0;
}
