    int x =42;

    void g(int y)
    static int x=7;

    It means that the function g() has an int x that is persistent between calls, and in that particular situation, it will only be initialized to 7 once (the first time g() is called), and subsequently it will have whatever value was left in it from the previous call. It's sort of a like a global variable, except it is not 'seen' except inside that particular function.
    The crows maintain that a single crow could destroy the heavens. Doubtless this is so. But it proves nothing against the heavens, for the heavens signify simply: the impossibility of crows.
