Question

PLEASE write the code in C++. employee.h, employee.cpp, and hw09q1.cpp is given. Do not modify employee.h and answer the questions in cpp files. Array is used, not linked list. It would be nice if you could comment on the code so I can understand how you wrote it

employee.h file

#include <string>
using namespace std;

class Employee {
private:
   string name;
   int ID, roomNumber;
   string supervisorName;

public:
   Employee();       // constructor

   void setName(string name_input);
   void setID(int id_input);
   void setRoomNumber(int roomNumber_input);
   void setSupervisorName(string supervisorName_input);
   void displayEmployee();
   string getName();
   int getID();
   int getRoomNumber();
   string getSupervisorName();
};

employee.cpp file

#include "employee.h"
#include <iostream>
#include <string.h>

using namespace std;

// Q1 Employee (2 points)
// Employee() constructor assigns the following default values to class data members
// name: John Doe
// ID: 0
// roomNumber: 101
// supervisorName: Jane Doe
Employee::Employee()
{
   name = "John Doe";
   ID = 0;
   roomNumber = 101;
   supervisorName = "Jane Doe";
  
}

// Q2 (18 points)
// 2 points for each function

// Define all the class member functions.
// While defining member functions, note that these functions will be called using
// a 'Employee' object which will represent one employee.
// Eg- Employee e[10]; creates 10 Employee objects
//       e[2].setRoomNumber(202); will set 3rd employee's room number to 202.

// setName assigns 'name_input' to class data member 'name'
void Employee::setName(string name_input) {
   Employeee

}

// setID assigns id_input to class data member 'ID'
void Employee::setID(int id_input) {
   // enter code here
  
}

// setRoomNumber assigns roomNumber_input to class data member 'roomNumber'
void Employee::setRoomNumber(int roomNumber_input) {
   // enter code here

}

// setSupervisor assigns supervisorName_input to class data member 'supervisorName'
void Employee::setSupervisorName(string supervisorName_input) {
   // enter code here
  
}

// displayEmployee displays the name, ID, room number and supervisor of the employee
// See expected output in question file.
void Employee::displayEmployee() {
   // enter code here
  
}

// getName returns the class data member 'name'.
string Employee::getName() {
   // enter code here
  
}

// getID returns the class data member 'ID'.

   // enter code here

// NOTE: you need to get a substring from user after printing a prompt. (Check the output in the pdf)
// HINT: You may refer to the document of string::find.
// 2. After step 1, you should find the employee whose name is the longest. You may use 'nameLength' and 'index' variable.
// 3. After step 2, copy the details of the employee to 'employeeWithLengthyName' object created using 'new'
// and display the employee's details using 'employeeWithLengthyName' object.
// NOTE: You necessarily have to use the 'employeeWithLengthyName' object to store the employee details in it and delete it after displaying.
// You should not display employee details using 'e[]' object.
// 4. Finally delete the 'employeeWithLengthyName' object.

Answer 1

Here is the answer for your question in C++ Programming Language.

Kindly upvote if you find the answer helpful.

NOTE : I have used dev-c++ to execute the code. Hence I had to include employee.cpp file instead of employee.h file in hw09q1.cpp file i.e., #include "employee.cpp". If including employee.h file works for you,please include that only.
