method implementation is as such

return type - classname::function

The private variables in the class are the ones your going to set from the parameters

so ill let you figure out where it goes but you will be using the code

1
2
 
name = employee_name
salary = initial_salary


that is very similar to one in another function

that is just for the employee class.

It is up to you to write the manager class methods.

Is all of that suppose to go above main?
I am getting a lot of errors I don't know where to put the functions or how to declare them...

no, the header files are separate *.h files.

If you are using Visual studio, they are neatly arranged in the explorer.

I have only used visual studio so far, so I do not know how other IDE's look and handle files.

your main.cpp will look something like

1

#include <iostream>

using namespace std;

#include "manager.h"


int main()
{  
   Manager harry("Hacker, Harry", 45000.00, "general");

   double new_salary = harry.get_salary() + 3000;
   harry.set_salary(new_salary);
   harry.print();

   cin.get();

   return 0;
}


ccc_empl.h and manager.h will be separate files.

you should look into getting a book on c++. I hear c++ primer is good I have 'C++ programming - program design including data structures'

#include<iostream>

#include "manager.h"

Manager::Manager(string name, double salary, string dept)
:Employee(name, salary), department(dept)
{
}

string Manager::get_department() const
{
	return department;
}

string Manager::set_department(string dept)
{
	Manager::department = dept;
}

void Manager:: print() const
{
	cout << Employee::get_name() << endl;
	cout << Manager::get_department() << endl;
	cout << Employee::get_salary() << endl;

Manager::Manager(string name, double salary, string dept)
:Employee(name, salary), department(dept)
{
}


should be

1

5
 
Manager::Manager(string name, double salary, string dept)
:Employee(name, salary)
{
department = dept;
}



1

void Manager:: print() const
{
	cout << get_name() << endl;
	cout << department << endl;
	cout << get_salary() << endl;
}



you don't need to resolve the scope for the class you are already in.
1
2
3
4
 
string Manager::set_department(string dept)
{
	department = dept;
}


and like i said before it should be manager.h
