H and cpp files - trying to build a file

Am I missing something in the h file? How can I get this to build?

My h file

Code:

#include "test30.cpp"
#include <iostream>

My cpp file

Code:

#include <iostream>
#include "test30.h"
using namespace std;

namespace first
{
  int x = 5;
  int y = 10;
}

namespace second
{
  double x = 3.1416;
  double y = 2.7183;
}

int main () {
  using first::x;
  using second::y;
  cout << x << endl;
  cout << y << endl;
  cout << first::y << endl;
  cout << second::x << endl;
  return 0;
}

I get the error:
test30.cpp(2): fatal error C1014: too many include files : depth = 1024

I bet someone on here can answer this in less than 10 seconds.

Why is the header file including the source file?

EDIT: You wrote that line of code. I'm asking what motivated you to do so.

Yes, we can tell you are new. And it's obvious you want to fix the problems. I'm trying to get you to learn something here.

You haven't answered my question.

File inclusion inserts the text of one source into another. What do you think happens when file A includes file B and file B includes file A? If the preprocessor or your IDE's dependency generator were not smart enough to spot it, a recursively infinitely growing file; that is what.

It does not matter how new you are to something, most newbs start by copying something that works, and you will not have seen this any where.

If that is your entire header file, it is entirely pointless, since if you remove the cpp inclusion (never include a cpp file BTW), you are left with <iostream> which your CPP file already includes. Nothing in your .cpp file needs anything that is not already in your cpp file or in iostream, so what is it for?

If when you write 'sensible' code it does not compile, post the code and the compile log and we can help.

Code:

#include <iostream>
using namespace std;

int firstX() {
  return 5;
};

int firstY() {
  return 10;
};

double secondX() {
  return 3.1416;
};

double secondY() {
  return 2.7183;
};



int main () {
  cout << firstX() << endl;
  cout << firstY() << endl;
  cout << firstY() << endl;
  cout << secondX() << endl;
  cin.get();
  return 0;
}

I believe this is what you're trying to do?
It should be just 1 file, if you're trying to do this ^.
The only thing you need to include is iostream
