Why not just try it and find out :) I don't see any reason why you shouldn't
be able to use an array this large. However, whenever I need more memory
than just a few bytes, I use a pointer and allocate the memory from the heap
instead.
In C++ that would mean using the new and delete operators or in C the
functions malloc and free. You should be able to use an array that large if
you prefer to do it this way.
