63. A copy constructor must receive its argument by reference instead of by value because: (A) Otherwise the constructor will only make a copy of a pointer to an object. (B) The copy of the argument passed by value has function scope. (C) The pointer needs to know the address of the original data, not a temporary copy of it. (D) Otherwise infinite recursion occurs. (E) Otherwise the constructor will never be called.
