It does get a bit difficult at times. The important thing is to break it up into plenty of functions, I use Dev Bloodshed C++ as my compiler, and it (like I suspect most if not all compilers) has an option to show classes, functions, and global variables. This feature I mostly use for functions, since with a single double click on the function name, it takes me where ever in the code I want to go. Also, liberal use of comments is always a plus, even if the code's function is completely obvious.
Oh, and a fun little tidbit in case you didn't know: in addition to system("pause"); you can use the other system commands available to the command prompt. system("color 0c"); is one I find particularly useful for warning the player if something bad is happening/about to happen (system("color"); will reset it to default). For other color combinations, type "help color" into your command prompt.
Here's my WIP sci-fi game... although at the moment its more of a generic text RPG game engine. I am fairly sure most of my includes are un-needed, but oh well... The apmatrix.h is hooked up to 3 other files I DLed, apmatrix.cpp apvector.cpp apvector.h, all 4 of which have been slightly modified (so I could add in a couple extra functions to apmatrix, namely an eraseRow and eraseCol function. The itemvector header file contains my itemvector class, which is essentially a class based version of the parallel vectors (and matricies) used for the area system. Both the itemvector and the area data stuff do more or less the same things, just different methodologies due to items needing to be rearanged, added, and deleted frequently.
