NO Errors or Warnings BUT I keep get an exception thrown when I hit "ENTER" once I input the first movie title. I need help with this code. This is Programming in C NOT C++
QUESTION: Modify Listing 17.2 so that it displays the movie list both in the original order and in reverse order. One approach is to modify the linked-list definition so that the list can be traversed in both directions. Another approach is to use recursion.
