using namepace std;
using std::string;
std::string instead of string
etc.

Решение

// Temp.h
#pragma once

#include <string>

class Temp
{
public:
Temp();

void doSomething(std::string blah);
};

I hate to post something so subtle, but this has me completely stumped on what I am doing wrong:
When I compile, it’s not liking Class Simulator at all. I get the error

syntax error : identifier 'Simulator'

at every instance of Simulator I use inside the DOCO header file. It also does this for my Pellet struct. The code was working completely fine until I started adding functions that work with the Simulator class inside DOCO.h.
The Simulator class uses the DOCO struct and the DOCO struct is using class Simulator. Is that a problem? Maybe I used included my headers wrong?

Here is a link to the error I get if it helps: http://msdn.microsoft.com/en-us/library/yha416c7.aspx

#include <iostream>
