between pointers and value type.
dynamic_cast:Dynamic_cast is used with pointers and
reference.It's purpose is - it provid valid object
conversion of requested class.
static_cast:Static_cast provides conversion from pointer to
related class not only from derived to base class.

passing a const object to a function.
