C++ Inheritance Access
Access Specifiers
You learned from the Access Specifiers chapter that there are three specifiers available in C++. Until now, we have only used public
(members of a class are accessible from outside the class) and private
(members can only be accessed within the class). The third specifier, protected
, is similar to private
, but it can also be accessed in the inherited class:
Example
// 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;
}
