Overriding, Shadowing, and Scopes

• Overloading an inherited member function hides that function:

class Employee
{  . . .
   virtual void set_salary(int new_salary);
};
class Manager : public Employee
{  . . .
   virtual void set_salary(int new_salary, int yearly_bonus);
};
Manager m;
m.set_salary(45000); // Error - requires 2 args
