Hehe, actually it is not homework.
Somebody gave me a test. And I failed on this problem. This problem
puzzled me
because there is function pointer involved.
Class Format(){};
class intFormat :public Format{};
class DoutbtFormat :public Format{}

How to design these classes so that
// The program:
main()
{
    double pi = acos(-1);
    cout << "easy as " << fmt(pi, 5, 2) << " ..." << endl;
    cout << "easy as " << fmt(pi, -10) << " ... " << endl;

}

Below you will find the declaration and the definition of the class

be
    added.
    The class is implemented as a template class. Your task is to
rewrite it
    for two types (int and double) without templates using
inheritance.
