Copy copy: revisited Main Constructor Copy Constructorh f(): global functionx=h

What happens if we don’t use it? Compiler creates one for you in the case of simple structures The default primitive behaviour: a bit-copy. C++ compiler will still automatically create a copy-constructor if you don’t make one The process the compiler goes through to synthesize a copy- constructor is called member-wise initialization.

Issues with pointers 50x A B {B=A;} Initial object Duplicate object

Deep vs Shallow copy Copy constructor is called only for initializations For assignment ? Operator overload ??
