 Answer to Question 3: Yes.
+**Question 4**: I have written some code, but it doesn't work. Can you check to see what is wrong with my code?
+Answer to Question 4: Unfortunately instructors are not responsible for checking student code.
+The fastest and easiest way for you to learn how to do the
+assignment, and to learn about thread programming, is to follow the advice in the assignment handout, copied below:
+In Section F, Hints, of the Assignment 2 description document, it is stated that,
+------------------------------------------------------------
+"1. You may start by trying to read and understand the program "alarm_mutex.c" in pages 52-58 of the book "Programming with POSIX Threads" by David R. Butenhof.
+. The program "alarm_mutex.c" and the file "errors.h" and "README" can be downloaded from the directory /cs/course/3221/assign2. Try to compile and execute this program by following the instructions in the "README" file.
+. The book "Programming with POSIX Threads" by David R. Butenhof has been put on reserve in Steacie Library."
+---------------------------------------------------------
+Once you have done that, it is most likely that you will also immediately know why your code doesn't work.
+**Question 5**: Can I use the cursor library in my assignment?
+Answer to Question 5: This question and the answer to it falls into the category of Question 1 and the answer to Question 1 above. You are not required to use the cursor library for doing the assignment. If you do choose to use the cursor library, you are completely on your own, and you should carefully document and justify all your design and implementation decisions in your report.
+**Question 6**: Can you confirm the input format. You state "The Airline, Flight, Departure_To, Scheduled_Time, Status, Revised_Time, and Terminal data are separated by one or more Tab characters."
+Is every field mandatory? Would two tabs appear only if a field is
+omitted, or can there be two tabs between Airline and Flight?
+Answer to Question 6: The input format should be EXACTLY as specified in the assignment, which is already clearly specified in Section A, Description of the Problem, Item 1, of the Assignment 2 description document:
+"... The Airline, Flight, Departure_To, Scheduled_Time, Status, Revised_Time, and Terminal data are separated by one or more Tab characters. For examples of the formats of the above data, see the “Greater Toronto Airports Authority – Live Flight Information” webpage:
+http://www.gtaa.com/en/travellers/search_results/?info=departures&all=true&submitting=true"
+It is up to you to figure out how to check the format of any user input, and how to detect possible errors in any user input.
