PLease Help with Class Implementation

hey guys,

I'm stuck with my final project and I would like a little help
This project is based on class implementation so here's the class that the teacher gave us

Code:

#ifndef ENGINEER_H
#define ENGINEER_H

//engineer class definition
#include<fstream>
#include<string>

using namespace std;

class Engineer
{
	private:
	string fName, lName, degree, hireDate;
	double salary;

	public:
	//constructor
	Engineer( string = "", string = "", string = "", string = "", double = 0.0 );

	//accessor functions
	string FName();
	string LName();
	string Degree();
	string HireDate();
	double Salary();

	//modifier functions
	void setFName( string );
	void setLName( string );
	void setDegree( string );
	void setHireDate( string );
	void setSalary( double );
	
	//input functions
	void getFName( istream& );
	void getLName( istream& );
	void getDegree( istream& );
	void getHireDate( istream& );
	void getSalary( istream& );
	
	//output functions
	void putFName( ostream& );
	void putLName( ostream& );
	void putDegree( ostream& );
	void putHireDate( ostream& );
	void putSalary( ostream& );
};

#endif

How could I start my implementation file What I need to do is ask the user for the first name, last, degree, hired date, and salary!
Could you guys just give me some advice thank you

Havn't you learnt about outputs yet?!?

Code:

cout << "First Name" << endl;
cin >> firstname;
cout << "Last Name" << endl;
cin >> lastname;
cout << "Degree" << endl;
cin >> degree;
cout << "Hired Date" << endl;
cin >> hireddate;
cout << "Salary" << endl;
cin >> salary;

of course I have I'm just stock creating the implementation file which contains all the class definitions but thanks anyway

Number one... we don't do homework here. So unless you're going to be more specific than "How do I start this", no one's going to be willing to help you. You also might want to read the sticky in the forum dealing with the homework policy.

Don't reply "Of course I have" to stuart's reply because you didn't give us any reason to believe you knew standard input... after all, you did ask how to get data from the user.

What you want to do is create a .cpp file, include this library, and just start your method definitions. Take it one at a time.

I'm sorry I didn't mean to offend anyone this is just frustrated because I can't figure it out.
Have a good day guys.

I will not write the code for you, but basicly, to use a function within a class like
SlyMaelstrom said in your ,cpp class inpelent file, you would do somthing like this

Code:

#include "dummyClass.h"   // use the class header file

constructor ( // goes here );

void dummyClass::setSalary ( double )
{
  // all code regarding this function goes here
}

in main, call the functions of the class, remember to add the class header file to main, and act on the code in the functiions. It really is that simple, you may want to read a little more into it, I have given you the basic idea - pete

if a constructor is define like this in the class
Engineer( string = "", string = "", string = "", string = "", double = 0.0 );
How could I initialize all the data members if they are already inizialize? for example in this program

Code:

unitvector::unitvector(): x(1), y(1), or(0)
{
}

if I want to initialize the elements in private could I do this

Code:

Engineer::Engineer(): fName(""), lName(""), degree(""), hireDate(""), salary(0.0)
{
}

I think you can still change the string. Just copy the string from users' input into the private members using the input functions in the class. Same thing with outputting. It's not that hard though. Good luck

thank you I'm going to try

{
}

That would be a default constructor. But to declare that one would be an error because there is already another constructor in your class that takes 5 parameters all of them with default values and that one could be called without parameters too.

I'm doing something like this

Code:

Engineer r();

	cout <<"Enter First name" << endl;
	cin >> firstname;
	r.getFName(cin);

It is giving me a compile error
the class implementation look like this

Code:

void Engineer::getFName( istream &input)
{
	input >> fName;
}

The second line does not applycout cin >> firstname;

cout <<"Enter First name" << endl;
r.getFName(cin);

why don't you use strcpy() to copy the string into the fName, instead using the istream.
