When no copy constructor is defined, the compiler supplies its own copy comstructor.

that is correct but take into consideration that the copy constructor only performs shallow copy of variables, meaning that if you use pointers or references to another objects, you will get 2 objects which points to the same addresses. and ince one object is deleted, if the references are properly cleaned, the other object will point to garbage values and you don't want that tl/dr: implement your own copy constructors

yes it is useful as it allows you to do certain things which would require a constr but better define your own
