Homework 3

As you are aware, we have lab assignments due every week. We also will have several homework assignments this semester, and this is the first. While the labs are directed, the homework assignments present larger problems that you should break down into smaller problems. You should spend some time thinking about and planning your homework solutions before coding/answering them.

For this homework, answer the following questions from the book:

Chapter 3, exercises 3.12, 3.15, 3.17, 3.18, and 3.23

For question 3.17, the book has "0 x 33 x 0 x 55". I believe that this is a typo, and should be treated as "0x33 * 0x55", i.e. "0x" specifying a hexadecimal value, thus asking you to multiply 33 (hexdecimal) by 55 (hexdecimal).

For question 3.18, the book says to divide 74 by 21, but then says that they should be unsigned 6 bit values. Because 74 is a 7 bit value, you should assume that it should be 74(octal) and 21(octal).

• An explanation is expected with every answer, and may count for half of the points or more. If your answer does not have an explanation, or that explanation is incomplete, expect to lose points. This is because we want to see how you arrive at the answer.
• These problems can be found in section 3.13 of your book (starting on page 246 of the physical copy).
• Since you are answering problems from the book, make a .pdf file like you do for the lab reports. It should have its own cover page. However, you do not need the different sections (e.g. introduction) that the lab reports have.
• As you are aware, certain types of assistance are inappropriate in this class. Read the collaboration policy given to you at the beginning of the semester, if you have any questions.
