Need this urgent please. Thank you.

computeSalary() : This function returns the total salary of the operator based on the hours. The rate is RM17.00 hourly and given the equation as: total = hour * 17 The member methods of class Executive: Executive (name:string, ID:int): Overloaded constructor. This constructor initializes the superclass's member attributes by calling the constructor of superclass Employee. It will then displays text "Executive name_of_executive created!". Given the main () of C++ code below. | #include <iostream> using namespace std; int main () { double hour; Operator op1 ("Ahmad", 10075); Operator op2 ( "Mary", 10179); Executive exel ("David", 9337); cout << "Enter total hours for operator " << opl.getName () << ": "; cin >> hour; opl.setHour (hour); cout << "Total salary for operator op1.computeSalary () << endl; " < opl.getName () << " is RM " << cout << "Total number of employee created = " < Employee::getCount () << endl; return 0:

(b) The class diagram below shows the relation of three classes of a program. The class Employee is a superclass of two derived classes, Operator and Executive. Employee - countEmp: int -name: string ID: int + Employee (name:string, ID:int) +getName () : string +getID ():int +getCount ): int Operator Executive -hour: double +Executive (name:string, ID:int) +Operator (name:string, ID:int) +setHour (hour:double):void +getHour (): double +computeSalary():double The member methods of class Employee: Operator (name:string, ID:int) : Overloaded constructor. This constructor initializes the member attributes and increases the static variable countEmp by 1. getName () : This function returns the value of member attribute name. getID (): This function returns the value of member attribute ID. getCount () : This function returns the value of member attribute countEmp. The member methods of class Operator: Circle (name:string, ID:int) : Overloaded constructor. This constructor initializes the superclass's member attributes by calling the constructor of superclass Employee. It will then displays text "Operator name_of_operator created!". setHour (hour:double) : This function sets the value of member attribute hour. getHour () : This function returns the value of member attribute hour.
