The compiler-generated copy constructor and assignment
operator are defined to do memberwise copying, not bit
copies. The compiler may implement these more efficiently
as it chooses, but it can do that for user-defined ones
as well.

You should avoid writing your own assignment and copy
constructors when you possibly can, and use the default
ones. If some member requires special copy handling,
then it should be of a type which encapsulates this.
Then adding new members doesn't require making any
changes to the copying code.
