Comment:

May be it`s a stupid question, but how can I use extern on 2d arrays?
When I declare in header
extern int array[][]
and then define in cpp file
int array[ROW_SIZE][COLUMN_SIZE]
it give me an error:
Error 1 error C2087: 'array' : missing subscript
Error 10 error C2087: 'array' : missing subscript
Error 21 error C2087: 'array' : missing subscript
Error 28 error C2369: 'array' : redefinition; different subscripts
Please help

I don't see anything wrong with Razor's suggestion. It should work. Of course, you need to have the constants ROW_SIZE and COLUMN_SIZE defined at the point where you have your declaration. Could that be the problem?
