Thread: Invalid storage class for a function.

My problem is probably a simple fix but I am having trouble figuring it out. I made a program and when I try to use the main driver to instantiate everything it says invalid storage class for a function. All of my code is in 4 separate files i'm just trying to get it to run now.

Code:

#include "stdafx.h"
#include <iostream>
#include <iomanip>
#include <fstream>
#include <string>
#include <conio.h>
#include "CashRegister.h"




int _tmain(int argc, _TCHAR* argv[])
{
    
    
    CashRegister register;
    register.run();
    _getch();
    
    
    return 0;
}
