Answer» Right answer is (a) If and only if the function is declared again in the same scope To EXPLAIN I WOULD say: The non-template functions can also be added with default arguments. This can be done even if the functions were defined earlier. This is because the call to the function won’t be affected. The function can still be USED in the same way as it was used earlier.
