Why don't C++ compilers define operator== and operator!=?
...om copy constructor, comparison operators and destructors because they use raw pointers in their implementation.
When using appropriate smart pointers (like std::shared_ptr), the default copy constructor is usually fine and the obvious implementation of the hypothetical default comparison operator ...

Why does the C++ STL not provide any “tree” containers?
