Based on the following declaration of the Employee class, and that Manager inherits from the Employee class, which of the following are true? class Employee { public: Employee(); Employee (string new_name); Employee (double new_salary); Employee(string new_name, double new_salary); void set_name (string new_name); string get_name() const; private: }; string name; double salary; The Manager class does not inherit the private data members. A Manager object has direct access to the name and salary inherited data members. The Manager class inherits name and salary, but Manager functions cannot change the values of either data member. O The Manager class inherits name and salary, but Manager functions can only change the values of the name data member.
