You can't. You can, however, declare a function returning any of:
A reference to an array
A pointer to an array
A vector
A structure containing an array,
etc.

You could also write a function that takes as a parameter a reference
or pointer to any of the above, and then populates the
referenced/pointed-to object instead of returning the same data.

Another option is to write a function that takes an output iterator as
a parameter. The function could then write to that iterator.

Which of these you should use depends on the actual problem that you're
trying to solve.

As has been pointed out, if you're working with C arrays you need to
be more specific about what you're trying to do in order to get a clear
answer. You don't have to return anything if the array already
exists--just pass it into the function. If the function creates it,
it'll have to allocate it on the heap and return a pointer.
std::vector<int*> would almost always be recommended unless you were
newly trying to learn the language. (After all, this isn't comp.lang.c
;-)
