Errors LNK2028 and LNK2019

[sharpie789]

I do not understand why my program won't work because of numerous LNK2028 and LNK2019 errors. I am using Microsoft Visual Studio Express 2012. 3 files make up this program. Any help is greatly appreciated! (I have weird names because I have made many copies....)

Here are my files:

Header take 2.h:

#pragma once
#include <iostream>
#include <string>
using namespace std;

class Heading
{
private:
string company, report;

public:
//Default constructor
Heading(void);
//Constructor
Heading(string company, string report);
//set and display company and report name
void setCompany(string c);
void setReport(string r);
void displayBoxed();
void displayOneLine();
};


heading take 2.cpp:

#include "header take 2.h"

//Default constructor
Heading::Heading(void)
company = report = " ";

//Constructor
Heading::Heading(string company, string report)
{
company = "ABC Industries";
report = "Report";
}
//Heading:setCompany
void Heading::setCompany(string c)
{
company = c;
}
//Heading::setReport
void Heading::setReport(string r)
{
report = r;
}
//Heading::displayBoxed
void Heading::displayBoxed()
{
cout << company << endl;
cout << report << endl;
}
//Heading::displayOneLine
void Heading::displayOneLine()
cout << company << report << endl;


Source1. cpp [main]:
#include <iostream>
using namespace std;

#include "header take 2.h"

int main()
{
string company;
string report;

cout << "Please enter the company name: ";
cin >> company;

cout << "Please enter the report name: ";
cin >> report;

Heading hdg;

hdg.setCompany(company);
hdg.setReport(report);
hdg.displayBoxed();
hdg.displayOneLine();

return 0;
}
