Efficient way of increasing array size by one element?

Hello,

Is there an elegant way to increase an array size without losing its data, or resorting to temporary storage?

I have this array that can vary in length from ~10 elements to ~1000000 elements. I don't really know the upper limit on its size. Currently, when I need to increase its size to add extra data, I have to copy its contents to a temporary array, deallocate the first one, reallocate it with a bigger size, and recopy the data, along with the new data. I was thinking that there must be a better way to do this, but I really don't know how. Any help would be greatly appreciated,

Thanks!

Alexis

With so many excellent discussions available at the touch of the forum search button, I won't attempt a complete answer. If you search a little further, you may conclude that the usual situation is to increase by a larger number of elements, to avoid excessive reallocation, and of course to arrange so that one copy of the data is sufficient rather than two.
