("must" was made bold by me)Originally Posted by C++ Primer, Lippman and others
I have trouble understanding the last phrase. Especially because while studying through this chapter, I've built a class that doesn't implement a default constructor. Maybe that "must" should be read "should". However, I cannot understand why I should (must?) define the default constructor.
Also, on a related note, is there any instance in which it may make sense to create a private copy constructor but still define it? I cannot fanthom for the life of me, a situation in which I will want only my member functions and friends to make copies.
