C++: Derived classes, "no matching constructor" error - c++

Question

I've been working on this assignment for a while. Here's the instructions:
You are to design an abstract class called Employee whose members are
as given below (make them protected):
Data members: char *name, long int ID
Two constructors: A Default constructor // intitialize data memebrs to
the default values and a copy constructor
Methods: setPerson (char *n, long int id) //allows user to set
information for each person A function called Print () // should be a
virtual function, that prints the data attributes of the class. and a
destructor
Also define two classes that derived from class Employee, called
Manager and Secretary. Each class should inherit all members from the
base class and has its own data members and member functions as well.
The Manager should have a data member called degree for his/her
undergraduate degree (e.g. diploma, bachelor, master, doctor), the
Secretary should have her contract (can be a Boolean value 1/0 for
permanent/temporary).
All member functions of derived class should be overrided from their
base class.
Write the following main() to test your classes
int main() {
Employee * p = new Manager(“Bruce Lee”, 0234567, “Dr.”);
P.print();
Secretary p2;
p2.setPerson(“Wilma Jones”, 0341256, “permanent”);
delete p;
p = & p2;
p.Print();
return 0;
}
This is everything I've come up with so far, but I'm pretty sure it's riddled with mistakes and that my arguments and variable types are all off.
#include <iostream>
using namespace std;
class Employee{
protected:
char *name;
long int ID;
public:
Employee();
Employee(Employee&);
void setPerson(char * n, long int eID) {
name = n;
ID = eID; };
virtual void Print(){
cout << "Name: " << name << endl;
cout << "ID: " << ID << endl; };
};
class Manager: public Employee {
protected:
char *degree;
public:
void setPerson(char * n, long int eID, char * d){
name = n;
ID = eID;
degree = d;
};
void Print() {
cout << "Name: " << name << endl;
cout << "ID: " << ID << endl;
cout << "Degree: " << degree << endl;
};
};
class Secretary: public Employee {
protected:
bool contract;
public:
void setPerson(char * n, long int eID, string c){
name = n;
ID = eID;
if (c == "permanent") contract = true;
else contract = false;
};
void Print(){
cout << "Name: " << name << endl;
cout << "ID: " << ID << endl;
cout << "Contract: " << contract << endl;
};
};
int main() {
Employee * P = new Manager("Bruce Lee", 0234567, "Dr.");
P.Print();
Secretary P2;
P2.setPerson("Wilma Jones", 0341256, "permanent");
delete P;
P = & P2;
P.Print();
return 0;
}
I'm getting an error on line 62 (the first line of the main code):
No matching constructor for initialization of Manager
I've tried reading similar questions, but they haven't helped me much. I think the most confusing thing is contract being a bool value and the use of char arguments. Any guidance at all is appreciated.

Answer 1

The error you're getting is pretty straight-forward: you don't have any constructor for Manager (or Employee) that takes a string, integer (?), and string as arguments.

Answer 2

You have declared the constructor employee but not defined it.
Look at the class employee, Under publc you have declared
Employee();
Employee(Employee&);
But you have not defined the function. You need
Employee :: Employee()
{
bla bla bla
}
and another one for the other signature.
