    char * msg = new char[65546]();
    

    It’s known as value-initialisation, and was introduced in C++03. If you happen to find yourself trapped in a previous decade, then you’ll need to use std::fill() (or memset() if you want to pretend it’s C).

    Note that this won’t work for any value other than zero. I think C++0x will offer a way to do that, but I’m a bit behind the times so I can’t comment on that.

    UPDATE: it seems my ruminations on the past and future of the language aren’t entirely accurate; see the comments for corrections.
