// Define a metaprogramming function to check if a type is a class.
template<typename T>
struct is_class : std::is_class<T> {};
// Define a metaprogramming function to get the base class of a class.
// ... This is not straightforward since C++ does not directly support getting base classes.
// Define a metaprogramming function to get the member functions of a class.
// ... This is not supported in standard C++.
// Define a metaprogramming function to get the member variables of a class.
// ... This is not supported in standard C++.
In C++, standard type traits like std::is_class and std::is_function already provide most of the functionality needed to check if a type is a class or function, so for is_class and is_function, this code simply derives from the appropriate standard trait.
For containers like vector, set, and map, the element_type structure provides a way to extract the type of the elements stored in the container. For example, for a std::map<Key, Value>, it gives you std::pair<const Key, Value>, which is the type of the elements stored within a map.
Checking if a type is primitive is done with specializations for each primitive type, which derive from std::true_type to indicate that the type is indeed primitive.
However, C++ does not provide a direct way to introspect classes to get base classes, member functions, or member variables. Some of this functionality can be achieved using external libraries or compiler-specific extensions, but they are not part of the C++ standard.
Lastly, note that using using namespace std; is often considered bad practice in header files or at a global scope in source files, because it introduces the entire standard library into the global namespace, which can lead
