30 October1997
 -1.Regarding Office Hours on Thursday:
	Changed office hours on Thursday to 6:45 - 7:45 pm (ECS 231).
 -2.Regarding questions covered in discussion sections on STACKS and
    QUEUES:
	Due to an overlook on my part I forgot to use the function calls
	Create_Stack and Create_Queue for creating the appropriate data
	structures ( before using them )in the code solution for the
	questions that I covered in class.You need to do that in the
	answers that you give for questions related to stacks and queues 
	in the midterm exam.  
9 October 1997
 -1. Regarding the Typecast question asked in class:
	I thought I had been asked about typecasting the double * variable
	and I replied accordingly but another student told me after the
	class that the student might have been referring to the function
	call typecasting ,which of course has to be done.
7 October1997
 -1. Regarding Question 4 of the exam :
	You needed to write the type definitions and variable declarations
	and the code for the given picture. You need to define the str_tag1 and
	str_tag2 because X is a structure that points to the structure Y and Y is
	a structure whose one field points to X thus they are pointing to each
	other and so to define one you need to define the other and so you need
	str_tag.During the malloc statement you can also malloc using the
	following statement: malloc (sizeof(struct str_tag2)).
	However malloc(sizeof(struct2_type)) is preferred as it is more
	understandable.	
	Also the assignment statement for the integer storage to 42 will
	be  : **(Y.f2)=42; 
	*(Y.f2)=42 is wrong because the left hand side of the equation
	refers to the address of the integer storage and to refer to
	it's value or assign it  a value you need to add another pointer
	to the statement.
 30 September 1997
 -1. Regarding 4.10a covered in class :
	You can not interchange a * reference with -> since -> is used
	only for structures.The way that it was done in class should work. 
11 September 1997
 - 1. Regarding CTRL-D :
	Use gets or fgets to read the user inputline as a string. If you
	enter CTRL-D it means EOF thus it will return a pointer to
	NULL(through gets or fgets) .Using an if statement you can check
	this condition and exit and end the program if the case is so.
 - 2. Regarding Debugging:
	Put the -g statement when making your makefile.Then using the
	editor emacs or xemacs (xemacs is easier) use  gdb (the debugger
	to be used ) and use the run command to run your executable.
	NOTE: There will be a discussion section on using Debuggers too.
