1) Explain why this program uses the exclamation operator with the strcmp() function.

2) Explain why the 'LENGTH' macro returns the length of an array. Would it work with a pointer to a dynamically allocated array? (Hint: understand sizeof).

3) Explain and fix the logical flow bug within the switch statement. (What happens when the -h option is used?)

4) Explain and fix the argument parsing error. (Why is entrycount never zero?)

5) Fix print_result() to print results correctly and in the same order as the words were specified on the command line. Explain your solution.
