These functions include: The automatic versions of the constructor and destructor don't do anything, but they will be there if you do not build them.

(The constructor you get is the "default constructor" -- no parameters -- and this is automatically built if you don't define any constructor besides the cop constructor).

This is sufficient for many cases, but not for ALL cases.

Example: This fraction object has a numerator of 3 and a denominator of 4.

I highly recommend the book “Elements of Programming” by Stepanov and Mc Jones.

Also look for presentations of Sean Parent on this topic.

to a function parameter means that the function will not make a copy.

Here it means the same thing: when the function returns a value, it will be the actual object we return, not a copy (normally, returning a value does make a copy).

This is the situation in which a shallow copy is not sufficient.

For instance, if the original object is storing the address 1024 in entry List, the copy will also get the 1024, and therefore the copy will be pointing to the original dynamic data!
