Well this seems to me to be a silly question to ask and I didn't realize it would be so hard to find an answer to. How can I declare global arrays in a multi-file program so that all the files in the program can access them? I'm using Ms Vc++ and it's not cooperating...I thought it would be a simple matter of sticking a modifier onto the declaration, but that doesnt seem to be working.

In header file
extern int array[];

In code file
int array[ARRAYSIZE];

To elaborate a bit on what cup said:

The array declaration (the code file bit) should go in only one .cc or .cpp (or whatever) file and should be placed outside of any functions (usually at the top of the file).

The extern definition should be available to every .cc (.cpp...) file that needs access to the array. Usually this is done by putting it in a header file that is included into every .cc file.
