<b>Derived Classes with Depth</b>

• Constructor(s), copy constructor,

assignment operator and destructor of

derived class called ?

<span class='text_page_counter'>(4)</span><div class='page_container' data-page=4></div>
<span class='text_page_counter'>(5)</span><div class='page_container' data-page=5>

Copy Constructor(1)

• A derived class has its own copy constructor.

• Derived class copy constructor is distinct from the

copy constructor of the base class.

• If we don't define a copy constructor for the
derived class, the compiler inserts one that

</div>
<span class='text_page_counter'>(6)</span><div class='page_container' data-page=6>

Virtual Operators

• Declaration syntax:

</div>
<span class='text_page_counter'>(7)</span><div class='page_container' data-page=7>
