How to use header functions in source file in C++? - c++

Question

I'm new to C++ programming language and it is different from Java. I tried to use functions from a header I made but when I use a function from the header , Eclipse C++ IDE says that member declaration is not found except for the constructor while it is found in the header as public.
Car.h file (header) :
#include <string>
using namespace std;
class Car {
private :
string name;
string model;
int year;
int width;
int height;
int depth;
public :
Car ();
Car (string n, string m, int y, int w, int h, int d);
void setName(string n);
void setModel (string m);
void setYear (int y);
void setSize (int w, int h, int d);
string getName ();
string getModel();
int getYear();
int getWidth();
int getHeight();
int getDepth();
};
Car.cpp file (source)
#include <iostream>
#include <string>
#include "Car.h"
using namespace std;
Car::Car(string n, string m, int y, int w, int h, int d) { //works properly
name = n;
model = m;
year = y;
width = w;
height = h;
depth = d;
}
Car::getName() { // IDE says member declaration not found
return name;
}
Car::getModel() { // IDE says member declaration not found
return model;
}
Car::getYear() { // IDE says member declaration not found
return year;
}
Car::getWidth() { // IDE says member declaration not found
return width;
}
Car::getHeight () { // IDE says member declaration not found
return height;
}
What I have did wrong ?

Answer 1

All of your functions are missing the return type, for example
string Car::getName() {
return name;
}

Answer 2

The reason why Car works is because it is a Constructor and does not need a type declaration.
All the rest of your functions do.
int Car::getYear() { // IDE says member declaration not found
return year;
}

Answer 3

Do this :-
#include <iostream>
#include <string>
#include "Car.h"
using namespace std;
Car::Car(string n, string m, int y, int w, int h, int d) { //works properly
name = n;
model = m;
year = y;
width = w;
height = h;
depth = d;
}
string Car::getName() { // IDE says member declaration not found
return name;
}
string Car::getModel() { // IDE says member declaration not found
return model;
}
int Car::getYear() { // IDE says member declaration not found
return year;
}
int Car::getWidth() { // IDE says member declaration not found
return width;
}
int Car::getHeight () { // IDE says member declaration not found
return height;
}
