C++ Inheritance


In C++, it is possible to inherit attributes and methods from one class to another. We group the "inheritance concept" into two categories:

  • derived class (child) - the class that inherits from another class
  • base class (parent) - the class being inherited from

To inherit from a class, use the : symbol.

In the example below, the Car class (child) inherits the attributes and methods from the Vehicle class (parent):


// Base class
class Vehicle {
    string brand = "Ford";
    void honk() {
      cout << "Tuut, tuut! \n" ;

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

int main() {
  Car myCar;
  cout << myCar.brand + " " + myCar.model;
  return 0;

Why And When To Use "Inheritance"?

- It is useful for code reusability: reuse attributes and methods of an existing class when you create a new class.
