C++ protected Keyword

❮ C++ Keywords


Example

Use the protected keyword to make an attribute accessible to a derived class:

// Base class
class Employee {
  protected: // Protected access specifier
    int salary;
};

// Derived class
class Programmer: public Employee {
  public:
    int bonus;
    void setSalary(int s) {
      salary = s;
    }
    int getSalary() {
      return salary;
    }
};

int main() {
  Programmer myObj;
  myObj.setSalary(50000);
  myObj.bonus = 15000;
  cout << "Salary: " << myObj.getSalary() << "\n";
  cout << "Bonus: " << myObj.bonus << "\n";
  return 0;
}

Definition and Usage

The protected keyword is an access specifier that declares attributes and methods as protected, which means that they are only accessible to methods within the class or methods from one of its derived classes.
