Thread: Including code from another .cpp file

How would I go about including code from another .cpp file into the one I'm working on?

Example: An RPG file called game.cpp has all the actual coding to control your character and the levels. A separate file called enemies.cpp has the information with all the monsters in the game. Another file called battle.cpp has the coding for the battle stage when you encounter the monster.

I want to include the other .cpp files almost like functions to be more orderly and to make things easier to edit. The simple #include enemis.cpp wouldn't work, would it, because there would be two main() functions?

Help is greatly appreciated.

Your enemies.cpp and battle.cpp shouldn't have a main() in them. They could contain defenitions to functions or classes pertaining to enemies and battle respectively. The forward declarations to those functions and classes are best put in a header file such as enemis.h and battle.h. You can then include those header file in your game.cpp to be able to use the functions and classes defined in the cpp files.

Edit: I made a program with just an int main() in it and include <class3.h> (my include file).

I took the H file directly from a program I had already compiled, and the compiler is saying there is "no such file or directory". I use MSVisualC++ Toolkit 2003. What's the problem?

Is the header in your working directory? or did you include the full path of where to find it in your #include?

It should be

Code:

#include "class3.h"

Only if he copied it to the working directory of his current project

Yeah, it's in the directory. Thanks, I'll try it now.
