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

i'm new c++ programming language , different java. tried use functions header made when use function header , eclipse c++ ide says member declaration not found except constructor while found in header 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   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 have did wrong ?

all of functions missing return type, example

string car::getname() {     return name; }
