Thread: Get .cpp and .h files to communicate...

I'm trying to figure out how to get my .cpp file to #include other .cpp and .h files. Here is a little test I setup:

main.cpp:

Code:

#include "stdafx.h"
#include "test.cpp"

int main()
{
    tester temp("Thins is the string");

	cout<<temp.GetString();
	
	getche();

    return 0;
}

test.cpp:

Code:

#include "test.h"

string tester::GetString()
{
	return teststring;
};

tester::tester(string newstring)
{
	teststring = newstring;
};

test.h:

Code:

#include <iostream>
#include <conio.h>

#ifndef _TEST_H
#define _TEST_H

using namespace std;

class tester
{
public:
	tester(string);
	string GetString();
private:
	string teststring;
};

#endif

I'm getting a couple of errors saying stuff like:
'#include "test.h"': skipped when looking for precompiled header use
binary '<<' : no operator found which takes a right-hand operand of type 'std::string'...

Thanks.
