Expert Solution & Answer
Chapter 3, Problem 1RE
Explanation of Solution
Public Interface of “Counter” class:
- The public interface of the “Counter” class includes “click()”, “getValue()” and “reset()” methods.
- The public interface specifies the functionality related to the class but it doesn’t include any information about the process of implementation of the functionality.
Explanation of Solution
Public interface differed from class implementation:
- The process of implementation of the functionality related to “Counter” class will not be explained.
- The implementation of a class is the code used in the tasks to support the functionality of the class.

I would like to get help to resolve the following case
Last Chance Securities
The IT director opened the department staff meeting today by saying, "I've got some good news and
some bad news. The good news is that management approved the payroll system project this morning.
The new system will reduce clerical time and errors, improve morale in the payroll department, and avoid
possible fines and penalties for noncompliance. The bad news is that the system must be installed by
January 1st in order to meet new federal reporting rules, all expenses from now on must be approved in
advance, the system should have a modular design if possible, and the vice president of finance would
like to announce the new system in a year-end report if it is ready by mid-December."
Tasks
1. Why is it important to define the project scope? How would you define the scope of the payroll
project in this case?
2. Review each constraint and identify its characteristics: present versus future, internal versus exter-
nal, and mandatory versus desirable.
3. What…
2. Signed Integers
Unsigned binary numbers work for natural numbers, but many calculations use negative
numbers as well. To deal with this, a number of different methods have been used to represent
signed numbers, but we will focus on two's complement, as it is the standard solution for
representing signed integers.
2.1 Two's complement
• Most significant bit has a negative value, all others are positive. So, the value of an n-digit
-2
two's complement number can be written as: Σ2 2¹ di 2n-1 dn
• Otherwise exactly the same as unsigned integers.
i=0
-
• A neat trick for flipping the sign of a two's complement number: flip all the bits (0 becomes 1,
or 1 becomes 0) and then add 1 to the least significant bit.
• Addition is exactly the same as with an unsigned number.
2.2 Exercises
For questions 1-3, answer each one for the case of a two's complement number and an
unsigned number, indicating if it cannot be answered with a specific representation.

Unsigned Integers If we have an n-digit unsigned numeral dn-1d n-2...do in radix (or base) r, then the value of that numeral is n−1 r² di Σi=0 which is basically saying that instead of a 10's or 100's place we have an r's or r²'s place. For binary, decimal, and hex r equals 2, 10, and 16, respectively. Just a reminder that in order to write down a large number, we typically use the IEC or SI prefixing system: IEC: Ki = 210, Mi = 220, Gi = 230, Ti = 240, Pi = 250, Ei = 260, Zi = 270, Yi = 280; SI: K=103, M = 106, G = 109, T = 10¹², P = 1015, E = 10¹8, Z = 1021, Y = 1024. 1.1 Conversions a.
