Question

(b) Address of object that is used for conversion

(c) Address of object that is mentioned in the syntax

(d) Doesn’t return any address

I had been asked this question during an interview for a job.

My question comes from Downcasting topic in division Default Arguments vs Overloading, Upcasting and Downcasting of Object Oriented Programming

Answer 1

The correct answer is (a) Address of object which is converted

For explanation: The address of the object which is converted is returned by the dynamic_cast operator. This is done to safely convert the subtype to supertype. This ensures the proper assignment and conversion from one type to another.
