What are the advantages of boost::noncopyable

Question

To prevent copying a class, you can very easily declare a private copy constructor / assignment operators. But you can also inherit boost::noncopyable.

Answer 1

It makes the intent explicit and clear, otherwise one has to see the definition of the class,and search for the declaration related to copy-semantic, and then look for the access-specifier in which it is declared, in order to determine whether the class is noncopyable or not. Other way to discover it by writing code that requires copy-semantic enabled and see the compilation error.
