How does it exactly work? What's the deal with > those curly brackets? Here's how you default-initialise every element of an array: int array[5] = {}; This works with every type.

I then create a reference to the first element: int array[1] = {}; int &i = *array; -- Frederick Gotham --- [ comp.std.c++ is moderated.
