dynamic_cast does and prints what?

[heidiK]

Hello everyone

Could anyone please help me with this online interview question?

Object1 and Object2 are the names of two different classes.
The Class Object2 has one Object and the Class Object1 does not have any objects
 
Object2 obj2 = new Object2();
cout << dynamic_cast< Object1>(obj2) << endl; ....... what does this line print?

Many Thanks

dynamic_cast can only be used to cast to pointers or references, so the code will print a nice compilation error. But if you were to cast an object correctly it'd return a pointer (printing the address it points to) or a reference (printing whatever it would print the class it was casted to).

OK thank you maeriden

Another question is: How do you assign const pointer to a non-const pointer. My answer was iii), is that correct?

i)	Reinterpret
ii)	Dynamic_cast
iii)	Const_cast - (YES)
iv)	Static_cast

[maeriden]

Yes.
