Creating a derived class

Creating a derived class

While taking a closer examination of the design of our Employee class, we might soon realize that the design is not flexible enough.  For example, each employee of a company is never just an employee – they all have specific functions and their own different attributes.  For example, a sales person should be the only person that can sell and they may even have an additional attribute like commission percentage.  A programmer, on the other hand, should be the only type of employee that can write code.  All employees, regardless of type may be hired exactly the same.
