In the last article, we looked at the std:is_base_of<T1, T2> type trait. One question that a reader asked since that article appeared is “How does is_base_of<> differ from the dynamic_cast<> operator?” Good question! In today’s post let me try to address the key differences between the two. I am not going to cover the dynamic_cast<> […]

For the official description, see this. std::is_base_of<A, B>::value takes two arguments, both classes (or structs), and returns true if A is a base class of B and false otherwise. Trivially, std::<A, A>::value is true. Let us look at an example […]
