Question

Which exception is thrown if the typecasting is not done properly?

(a) bad_type_cast

(b) bad_any_cast

(c) type_mismatched

(d) bad_cast_mismatched

This question was posed to me in unit test.

My enquiry is from STL Container Any topic in section Class Hierarchies, Library & Containers of C++

Answer 1

Correct choice is (b) bad_any_cast

Best explanation: bad_any_cast exception is thrown when typecasting is not done properly by the user i.e. if any is storing int value and we are trying to cast it into a string then the program will throw bad_any_cast exception.
