(Solved): 1. Add or modify the following operations to the classes named: void setName(string theName); ...

1. Add or modify the following operations to the classes named:

void setName(string theName);      // change the name of the employee
void setPayRate(float thePayRate); // change the hourly or salary pay rates
float pay(float hoursWorked) const; // calculate the total income
void print() const              // print the employee information including all attributes such as name, salaried, payrate, etc.. 

2. Define a new class for Supervisor. A supervisor is a manager who responds to employees in a specific department. It should

• Have a field to store the department name (as a string).
• Have a bonus payment on top of the basic salary.
• Always be salaried (i.e., pay for a single pay period is fixed, no matter how many hours worked).
• Have a constructor that takes initial values for all fields.
