Question

We can assign ______________________

(a) Value of one reference variable to another

(b) Value of any object to another

(c) Value of any type to any object

(d) Value of non – reference to another reference

The question was asked in a job interview.

Origin of the question is Assigning Objects in section Assigning Object, Pointer to Objects, Passing and Returning Object of Object Oriented Programming

Answer 1

Right answer is (a) Value of one reference variable to another

The best I can explain: Only the reference value can be assigned to another reference value. This is because both deal with the address. There is no type mismatch hence we can assign them.
