IT16 Case Study 6: Malicious Programs

You have learned that a friend of yours is developing a worm to attack the administrative systems at your institution of learning. The worm is “harmless” and will simply cause a message – “Let’s party” – to be displayed on all workstations connected to the computers on Friday at 3 pm to 4 pm the virus will erase itself and destroy all evidence of its presence. What would you do?

IT16 Case Study 5: Hacking

What would you do...

You have just been hired as an IT security consultant to “fix the security problem” at Acme United Global Manufacturing. The company has been hacked mercilessly over the last six months, with three of the attacks making the headlines of the business section for the negative impact they had on the firm and its customers. You have been given 90 days and a budget of $ 2 million. Where would you begin, and what steps would you take to fix the problems?

IT5 OOP Prelim Lab Exam

Computers are playing an increasing role in education. Write a program that will help an elementary school student learn multiplication. Use the Next method from an object of type Random to produce two positive one-digit integers. It should display a question, such as

How much is 6 times 7?

The student should then type the answer into a TextBox. Your program should check the student’sanswer. If it is correct, display "Very good!" in a Label, then ask another multiplication question. If the answer is incorrect, display "No. Please try again." in the same Label, then let the student try the same question again until the student finally gets it right. A separate method should be used to generate each new question. This method should be called once when the program begins execution and then each time the user answers a question correctly.

IT311 - OOP Laboratory Exercise 5

Java Laboratory Exercise 5

Instructions:

Due: December 15, 2010 11:59 pm.
Send the class file and the main program (Household.java and TestHousehold.java)
Attach and email the files in celticguardiandancingelf@yahoo.com
Subject: Lastname__it311_labexer5

a.) Create a class named Household that includes data fields for the number of occupants and the annual income, as well as methods named setOccupants(), setIncome(), getOccupants(), and getIncome() that set and return those values respectively. Additionally, create a constructor that requires no arguments and automatically sets the occupants field to 1 and the income field to 0. Save this file as Household.java.

b.) Create a program named TestHousehold that demonstrate that each of the methods works correctly.

c.) Create an additional overloaded constructor for the Household class you created. This constructor receives an integer argument and assigns the value to the occupants field. Add any needed statement to TestHousehold to ensure that the overloaded constructor works correctly.

d.) Create a third overloaded constructor for the Household class you created. This constructor receives two arguments, the values of which are assigned to the occupants and income fields, respectively. Alter the TestHousehold program to demonstrate that each version of the constructor works properly.

IT5 Lab Exercise 3

It will be checked on December 7, 2010

The factorial method is used frequently in probability problems. The factorial of a positive integer n (written n! and pronounced “n factorial”) is equal to the product of the positive integers from 1 to n. Even for relatively small values of n, the factorial method yields extremely large numbers. For instance, when n is 13, n! is 6227020800—a number too large to be represented with data type Integer (a 32-bit integer value). To calculate the factorials of large values of n, data type Long (a 64-bit integer value) must be used. Write a program that evaluates the factorials of the integers from 1 to 20 using data type Long. Display the results in a two column output table. [Hint: create a Windows application, use Labels as the columns and the vbCrLf constant to line up the rows.] The first column should display the n values (1–20). The second column should display n!.

IT 16 Case Study 3: Applying Ethical Theories

A programmer, after returning from a holiday to an underdeveloped country, was deeply affected by the level of poverty. when he returned to his job in a large international corporation, it occurred to him that he could write a program that filtered off small amounts of money from the advertising account and pay it to a private account. His idea was to collect enough money to provide IT equipment and training to the people in the town he had visited on holiday. However, he is not sure about his decision. What should he do?

a) What solution does a Kantian approach offer?

b) What solution does a consequentialist approach offer?

c) Are their conclusions the same?

d) What do you think he should do?

IT311 - OOP Laboratory Exercise

Problem: Sorted Words

Background: What background? Seemed like a good idea at the time...
Input: Anyway, you're to write a program that reads in a whole bunch of words (each word is no more than 20 characters). For our purposes, words are to be separated by spaces, commas (,), !, ?, and periods (.). No word goes past the end of a line. All comparisons should ignore case.
Output: Output the sorted words, one per line, in lower case.
Sample Input:
How much wood would a woodchuck chuck if a woodchuck could chuck wood? Well? What
do you think? Are you feeling well?

Sample Console:
a
a
are
chuck
chuck
could
do
feeling
how

IT5 - OOP (VB .Net) Lab Exer 1 and 2

Lab Exer 1
1. Develop a program that determines if a department store customer has exceeded the credit limit on a charge account. For each customer, the following facts are available:
a) Account number
b) Balance at the beginning of the month
c) Total of all items charged by this customer this month
d) Total of all credits applied to this customer's account this month
e) Allowed credit limit
The program should input as Integers each of these facts, calculate the new balance
( = beginning balance + charges – credits)
display the new balance and determine if the new balance
exceeds the customer's credit limit. For those customers whose credit limit is exceeded, the program
should display the message, “Credit limit exceeded.”

Lab Exer 2
2.A palindrome is a number or a text phrase that reads the same backwards as forwards. For example, each of the following five- digit Integers are palindromes: 12321, 55555, 45554 and
11611. Write an application that reads in a five-digit Integer and determines whether it is a palindrome.
[Hint: Check if 1st digit equals 5th, 2nd digit equals 4th.]
