No Default Constructor

[cdashdash]

I am getting an error on line 13 of the .cpp saying there is no default constructor. Any help would be appreciated.

Employee.h

#ifndef EMPLOYEE_H
#define EMPLOYEE_H
#include <string>
using namespace std;

class Employee
{
	private:
		string employeeName;
		int employeeNumber;
		string hireDate;

	public:
		Employee (string eName, int eNumber, string hDate)
		{
			employeeName = eName;
			employeeNumber = eNumber;
			hireDate = hDate;
		}

		void setEmployeeName (string eName)
		{
			employeeName = eName;
		}

		void setEmployeeNumber (int eNumber)
		{
			employeeNumber = eNumber;
		}

		void setHireDate (string hDate)
		{
			hireDate = hDate;
		}

		string getEmployeeName()
		{
			return employeeName;
		}

		int getEmployeeNumber()
		{
			return employeeNumber;
		}

		string getHireDate()
		{
			return hireDate;
		}
};

#endif 

ShiftSupervisor.h

		void setSalary(int empSalary)

		{
			bonus = empBonus;

		int getSalary()

			return salary;

};

A "default constructor" is the constructor that takes no arguments.

ShiftSupervisor shiftSupervisor;  // <- this will default construct a ShiftSupervisor
    // because you are not using any arguments when calling the constructor 

However, the only constructor in the ShiftSupervisor class takes five arguments. Therefore there is no default constructor that you can call, which is why you get this error.

Solutions are:

1) Use the constructor you wrote, rather than the default constructor (this means you would create your shiftSupervisor object after you got all the input from the user, and pass all that data to the constructor rather than calling your setters).

or

2) Write a default constructor for your ShiftSupervisor and Employee classes.

Okay. I added default constructors to my headers. Now when I run the program, it prompts for a name and then terminates. Any idea how to fix this?

Here is the updated code...

Employee.h

#ifndef EMPLOYEE_H
#define EMPLOYEE_H
#include <string>
using namespace std;

class Employee
{
	private:
		string employeeName;
		int employeeNumber;
		string hireDate;

	public:
		Employee()
		{
			employeeName = "";
			employeeNumber = 0;
			hireDate = "";
		}

		Employee (string eName, int eNumber, string hDate)
		{
			employeeName = eName;
			employeeNumber = eNumber;
			hireDate = hDate;
		}

		void setEmployeeName (string eName)
		{
			employeeName = eName;
		}

		void setEmployeeNumber (int eNumber)
		{
			employeeNumber = eNumber;
		}

		void setHireDate (string hDate)
		{
			hireDate = hDate;
		}

		string getEmployeeName()
		{
			return employeeName;
		}

		int getEmployeeNumber()
		{
			return employeeNumber;
		}

		string getHireDate()
		{
			return hireDate;
		}
};
