Questions

1. What are the side effects of macros?
2. What is a class/function template? What is a template class/function?
3. What is a template parameter list? What is a template argument list? Once we have a class template, we can instantiate it either explicitly or implicitly. In what kind of scenario is explicit instantiation necessary?
4. What does polymorphism mean in C++? What is the difference between function overloading and function overriding?
5. What are type traits? How do we implement a type trait?
6. In the ch4_5_class_template_implicit_inst_B.cpp file, we said implicit instantiation generates the X<int> class, and then creates the xi object and generates the X<int>::f() function, but not X<int>::g(). How can you verify that X<int>::g() is not generated?
7. Using template metaprogramming, solve the problem of f(x,n) = x^n, where n is a const and x is a variable...
