class Department {
//define data members
  private;
     string name; //name of department
   
     FacultyMember fac []; //define array containing all faculty members of a department
     Staff staff []; //define array containing all staffs of a department
   
     //methods
  public:
     Department();//Default constructor
     
     Department (string name);/Paramerterized constructor
     
     void setFaculty( FacultyMember f [ ] );
   
   void setStaff ( Staff staff [ ] );
   
   };

2.     Interface of Faculty_member class

 

class FacultyMember {

   double salary;
 
   //Methods
 public:
   FacultyMember(); //default constructor
   
   FacultyMember (string name,string cnic, string qualification, double salary);//parameterized constructor
 
};

 

3.     Interface of Staff class

class Staff {
 
   //define data members
  private:
     string name;
     
     string cnic;
     
     int hoursWorked;
     
     double hourlyRate;
   
     //Methods
  public:
     Staff (); //default constructor
       
     Staff (string name,string cnic, int hoursWorked, double hourlyRate);//parameterized constructor
     
};
