Make sure that film.c and data.txt are in the same folder.

1. Compile, run, and observe how film.c.

2. You are expected to engineer the functions: list, find, update, and sort.

3. Your performance will be graded with respect to your sort function. So, youd better start from the sort function.

4. The scope of these functions is up to your imagination and talent.

5. The assessment will be made with respect to the quality of your program. So handle as much exceptions as possible.
