Thread: Dereferencing begin() for an empty STL vector

Hi:

I would like to know if it is safe to do something like the following:

std::vector<int> arr;
int* arrPtr = &(*arr.begin());

I know that it is a valid thing to do if arr is not empty. I am not so sure about the case when arr is empty.

Any help would be greatly appreciated.

Thanks.

Rahul

Not safe.
