The error message is correct. Maybe you want to make the data members protected. — drescherjm, Jun 21 '21 at 18:59
Derived classes can only see `protected` and `public` members, not `private` from the base class. — Cory Kramer, Jun 21 '21 at 18:59
You may want `const string& n` instead of `string& n` for the first argument of `HourlyEmp::HourlyEmp`. — MikeCAT, Jun 21 '21 at 19:00
As the error clearly says, the variable `Employee::taxRate` is private hence it cannot be accessed outside Employee class. You are trying to access it from the inherited class SalariedEmp which will not work. In order to do that you need to define it as `protected` — Beshambher Chaukhwan, Jun 21 '21 at 19:04
but now i am getting an other error. [Error] no matching function for call to 'SalariedEmp::SalariedEmp(const char [4], double, double)' — azhar, Jun 21 '21 at 19:16
@azhar if you have a new question, please [post a new question](https://stackoverflow.com/questions/ask). — Drew Dormann, Jun 21 '21 at 19:25
