 **Question 1**: We are planning to add a certain additional functionality X to our program for the Assignment. Is adding the additional functionality X allowed?

 You are allowed to modify the main() procedure and the alarm_thread in any way that meets the assignment requirements.
-**Question 5**: For Assignment 2, are we allowed to NOT use the alarm_list?
+**Question 5**: We are start writing the code for assignment 2. One issue we found is the
+code you give us has the problem when user input as following:
-Answer to Question 5:
+alarm> 10 hello
-In the assignment description, it states that,
+alarm> 5 world
-***********************************************************
+alarm> (10) hello
-"A3. You are required to make the following changes to the program
-"alarm_mutex.c" to produce a program named "My_Alarm.c".
-In your program "My_Alarm.c", after the alarm_thread has retrieved each
+(5) world
-alarm request from the alarm_list, instead of waiting for the specified
-number of n seconds and then printing out the alarm message as done in
-"alarm_mutex.c", the alarm_thread will immediately create a new thread,
-and that new thread will print out the alarm message repeatedly, once
-every n seconds; while the alarm_thread will be free to continue to
-retrieve and process new alarm requests from the alarm_list."
-**************************************************************
-In the assignment description, it clearly mentions "alarm_list" more than once, so clearly, using the "alarm_list" in the original "alarm_mutex.c" program is an important component of the assignment requirements. So the answer is that you MUST use the "alarm list" in your program "My_Alarm.c".
+The message "world" will not be sent back before hello although the time is
+set before "hello". In the book, there is another version of alarm which
+used condition mechanism could solve this problem. Should we implement
+assignment 2 base on that code or just leave this problem and still use the
+code you gave us?
-**Question 6**: For Assignment 3, can I include the errors.h file that was used in Assignment 2?
+Answer to Question 5:
-Answer to Question 6: Yes.
+What do you mean by "Should we implement assignment 2 base on that code"?
+Assignment 2 never asked you to write assignment 2 "based on" ANY code.
+The sample code was only provided for the purpose of illustrating some of the concepts discussed in the book related to POSIX Threads.
+No one has ever said that the sample code should be used or can be used to satisfy the requirements of assignment 2.
+**Question 6**: Some members of my assignment group are doing less work / making less
+effort / contributing less. Is this a valid reason for not handing in the assignment before the due date?
+Answer to Question 6:
+Unfortunately a claim that some members of an assignment group
+are doing less work / making less
+effort / contributing less than some other members of the assignment
+group, is NOT a valid reason for not handing in
+an assignment on or before the assignment due date.
+If any member of any assignment group wishes to receive any credit
+for any assignment,
+that assignment group would need to hand in the assignment
+on or before the assignment due date.
