Thread: c++ classes

I took c++ a long time ago in school, now I am trying to relearn everything again. I think this is a very stupid question but I don't care, here it goes:

Code:

//test.cpp

#include "point.h"

using namespace std;

int main()
{

  Point pt1;

  pt1.set_x(1234);
  pt1.print_x();

}

----------------------------------------------------------------

Code:

//point.h

#ifndef POINT_H
#define POINT_H
#include "point.cpp"

class Point
{

 public:
  void set_x( int new_number );
  void print_x();

 private:
  int x;

};


#endif

------------------------------------------------------------------

Code:

//point.cpp

#include <iostream>

void Point::set_x( int new_number)
{
  x = new_number;
}


void Point::print_x()
{
  cout << "\nThe value for x is : " << x << endl << endl;
}

Ok so that is my code, as you can see three (3) different files.
When I try to compile this is what happenes:

bash-3.00$ g++ test.cpp
In file included from point.h:3,
from test.cpp:1:
point.cpp:3: error: syntax error before `::' token
point.cpp:9: error: syntax error before `::' token
bash-3.00$

What am I doing wrong here. I have tried to do it many different ways, but nothing seems to work. Please, help!!

Thanks,

#include "Point.h"

add that to Point.cpp and remove #include "Point.cpp" from Point.h

You have it backwards

I tried that, but this is the error whenever I compile that way:

Code:

lab35->g++ test.cpp
/tmp/ccWqOfOU.o(.text+0x1d): In function `main':
: undefined reference to `Point::set_x(int)'
/tmp/ccWqOfOU.o(.text+0x2c): In function `main':
: undefined reference to `Point::print_x()'
collect2: ld returned 1 exit status
lab35->

The code itself seems to be right, cause when I put everything in the .h file, it compiles with no problems. It is when I move the functions to their own .cpp file that the prolems arise.

Thanks for the help.

PS: I am on a RH Linux pc, but I get the same errors on slackware and Ubuntu.

Oh cool!!. That is what I was doing wrong. and also I did not had the using namespace std in the file. Thank you both a lot.
