Homework

Homework #01 (UNIX account; due Jan 24)
Homework #02 (C pretest; due Jan 28)
Homework #03 (Arrays in Perl); due Apr 22)

hw #1:

Try your UNIX account on the department Sun machines by this date. Although the machines are linked, and it usually doesn't matter which one you're on, this time you need to make it to monet, since that's the one where I'll be checking the system log.

If you have any problems logging into that account, let me know about them, together with your student ID (the one you use for Novasis), but not at the last minute. Let me know by noon on Jan 22.

hw #2:

C Pretest. This is for a (small) grade, but you may consult with any classmates and any resources you wish. You need to do the writing and emailing yourself If you're submitting it electronically, don't do it via the website (like labs); just email it to Akhil, with cc to me.

1. What's the UNIX command for compiling a C program that is in a source file called prog.c?

2. What would be the output of the following fragment?
for (k=1; k<3; k++)
printf("%d\n",k);

3. Why is the getchar() function made to return type int and not char? When do you get in trouble by storing its return value in a char variable?

4. What's the difference between math.h and "the math library"?
5. List the classmates and text or online resources that you consulted on these questions.

hw #3:

Look over the four Perl programs (p1, p2, p3 and p4) here. For each program,
(1) Predict the output;
(2) Run the program;
(3) Understand any deviation the actual output may have had from your prediction.

Hand in your results of (2) at the beginning of class (or email to Akhil and me by then).
