how to make Inheritance dependence - c++

Question

I'm triying to make this exercise:
There are different types of employees: regular
workers,supervisors,board members which are specific types of
supervisors
Track the number of objects of type regular worker.
Each employee has its name and surname and can introduce himself.
Each employee object has its own worker id which is assigned to him
while it is created
The salary is calculated is specific way depending on the type of the
employee.
Each employee can have its direct supervisor which can be any
supervisor(it means that for example a board member can be a
supervisor of regular worker)
Now i had made all of point, exclude the last point:
class Employees
{
public:
static int workerid;
int salary;
Employees(){
workerid += 1;
}
void introduce(){
cout << "the name is:" << name << "and surname" << surname << endl;
}
};
int Employees::workerid = 0;
class Supervisors :public Employees{
public:
Supervisors(){
salary = 1000;
}
};
class BoardMembers : public Supervisors{
public:
BoardMembers(){
salary = 1200;
}
};
class RegularWorkers :public Employees{
public:
static int number;
Supervisors *supervisor;
RegularWorkers(Supervisors supervisor){
this->supervisor = &supervisor;
number += 1;
salary = 600;
}
};
int RegularWorkers::number = 0;
(i think until the last point is ok), but for the last point I need one id of the supervisor but how to made the supervisor or boardemember assign to the regularworker?
Thank you & best regards

Answer 1

Modify the employee class by adding a Supervisor
Supervisor *supervisor;
And then overload the Employee constructor to accept type Supervisor and set them equal to each other.
Employees(Supervisor *s){
supervisor = s;
workerid += 1;
}
Then you can access the Supervisor's ID by using
supervisor->ID
Also you may want to include name and surname as member variables and initialize those as well in the constructor. To add to the previous constructor it might look like this.
Employees(Supervisor *s, string sName, string sSurname){
name = sName;
surname = sSurname;
supervisor = s;
workerid += 1;
}
