I think it depends on the type of data your are talking about.\
I have in one program for instance a global instance of a class representing
the map in my game.
There will only every be one instance of this class, and the WHOLE program
is build around it so it makes sence to be global. However use of global
variables should be carefuly considard. Usally the pros. outweigh the cons.

Doesn't help most of the times, but creates a nuisance instead. It's a bad
practice to do this. Things like this can be used only for a single
program, certainly not for a large project.

Don't think this is a good idea. What Damian has said would get you a
better program. If the array is too large, consider using malloc.
