    You mean the C++ standard. As far as I know, C doesn't have namespaces, so you wouldn't have to worry about using directives, now would you?

    I don't particularily like it either, but I think it's preferable to using namespace std.

    Of course it is preferable. It has the merit of at least not defeating entirely the purpose of a namespace.

    If there would be something to wipe out of ones memory, that something would be using namespace std.

    Like you do: datalist *temp = new datalist();
    Still no-one answered me?

    Can't say as I've ever dynamically allocated space for an object of a templated class, but I expect it would be something like this, assuming type t will be type double.

    datalist<double> *temp = new datalist<double>;
