Does the arrangement of various files in a project play a large role when you get to programming for the real world?

Still confused...

How would I use multiple cpp files in my project? I've read over "Organizing Code Files in C and C++" here at GameDev, and know how to #include and use headers for class definitions, etc, but I'm still fuzzy about how I would do something like:

1. I have a main.cpp file for a Zork-esque text adventure. When the user selects "new game", I want to move to the first part of the game, which would be inside a house. I don't want to put all the text and functions for the house inside main.cpp, and I don't think that house.h included in main.cpp would be appropriate, (though I'm not 100 percent sure here). I tried just #include (ing) the source "house.cpp" within main.cpp, but the compiler didn't seem to like that.

Thanks again!

      #include <iostream>#include "main.h"#include "house.h"using namespace std;//Function Delcarations are in Main.Hvoid main(){   cout<<"Running a Procedure in Main now"<<endl;   MainProc();   cout<<"Done Running Main Proc"<<endl;   cout<<"Entering the House Procedure Now"<<endl;   House();   cout<<"Returned from the House Procedure"<<endl;}//Function Definitionsvoid MainProc(){   cout<<"This is a Procedure in Main.cpp!!!!"<<endl;}  

                //In the Header File, we include the Function Definition//We can then include this header file in any .CPP file that//needs this Procedure.//Don't forget Inclusion Guards in ALL your Headers#ifndef INC_MAIN_H#define INC_MAIN_Hvoid MainProc( void );#endif //INC_MAIN_H  

                //In House.cpp we could include the Functions for Displaying//What is in your house. Remember that any .CPP file that will//need the procedures here, you will have to include House.H#include "House.H"#include <iostream>using namespace std;//The Function Definition for House() is in House.Hvoid House(){   cout<<"This Procedure is in the House.cpp file!!!!"<<endl;}  

          //Inclusion Guard Again#ifndef INC_HOUSE_H#define INC_HOUSE_H//Fuction Definitionvoid House( void );#endif // INC_HOUSE_H

Hi all,
Forgive more newbie questions, but I have a couple that I hope will make things a bit clearer.

First:
What the heck are inclusion guards? What kind of weapons do they have? Err....nevermind the poor attempt of humor.

//Don't forget Inclusion Guards in ALL your Headers
#ifndef INC_MAIN_H
#define INC_MAIN_H


The other question might seem like a basic question, but why do you need to do the #include main.h in the house.cpp? You don't seem to be calling any functions in the main.cpp from the house.cpp. To me that seems that it is not needed. Or could it be just good practice to do so?

Thanks,
Triston
