    queue of int arrays

    I know I can do this:

    Code:
    queue<int*>
    But then I have to allocate and deallocate each member. I also know I can:

    Code:
    queue< queue<int> >
    But I don't like that because I don't need a queue of queues. All I need is a queue of arrays:

    Code:
    queue<int[4]>
    But int[4] is not a real datatype. Or have I missed something?

    What about
    queue < vector < int > >
    then?
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    Sure, but the "low level" guy in me just says that shouldn't be necessary. I was hoping there was a way to use fixed size arrays in a template, but if there isn't, I won't loose any sleep.

    maybe something like this?

    Code:
    struct myt {
        int data[4];
    };
    
    queue<myt> myq;
    Stick close to your desks and never program a thing,
    And you all may sit in the standards commitee!

    Shucks, I guess that is pretty obvious, thanks.

    There is still std::array.
