Answer:
Rules for naming variables:
- Variable names in Visual C++ can range from 1 to 255 characters. To make variable names portable to other environments stay within a 1 to 31 character range.
- All variable names must begin with a letter of the alphabet or an underscore ( _ ). For beginning programmers, it may be easier to begin all variable names with a letter of the alphabet.
- After the first initial letter, variable names can also contain letters and numbers. No spaces or special characters, however, are allowed.
- Uppercase characters are distinct from lowercase characters. Using all uppercase letters is used primarily to identify constant variables.
- You cannot use a C++ keyword (reserved word) as a variable name.

Consider the following two data structures for storing several million words.
I. An array of words, not in any particular order
II. An array of words, sorted in alphabetical order
Which of the following statements most accurately describes the time needed for operations on these data structures?
A. Finding the first word in alphabetical order is faster in I than in II.
B. Inserting a word is faster in II than in I.
C. Finding a given word is faster in II than in I.
D. Finding the longest word is faster in II than in I.
Answer:
The correct answer is C.
Explanation:
Finding a given word requires the search operation. The search operation is faster in a sorted array compared to an unsorted array. In a sorted array the binary search method is used which runs on logarithmic time while in an unsorted array, there's no other way than linear search which takes O(n) time on the worst case where the required word is not in the array.
The statement which most accurately describes the time needed for operations on these data structures is: C. Finding a given word is faster in II than in I.
What is a binary search?Binary search can be defined as an efficient algorithm that is designed and developed for searching an element (information) from a sorted list of data, especially by using the run-time complexity of Ο(log n)
Note: n is the total number of elements.
In Computer science, Binary search typically applies the principles of divide and conquer. Thus, to perform a binary search on an array, the array must first be sorted in an alphabetical or ascending order.
In conclusion, the statement which most accurately describes the time needed for operations on these data structures is that, finding a given word is faster in data structure II than in I.

You work for a small company that exports artisan chocolate. Although you measure your products in kilograms, you often get orders in both pounds and ounces. You have decided that rather than have to look up conversions all the time, you could use Python code to take inputs to make conversions between the different units of measurement.
You will write three blocks of code. The first will convert kilograms to pounds and ounces. The second will convert pounds to kilograms and ounces. The third will convert ounces to kilograms and pounds.
The conversions are as follows:
1 kilogram = 35.274 ounces
1 kilogram = 2.20462 pounds
1 pound = 0.453592 kilograms
1 pound = 16 ounces
1 ounce = 0.0283 kilograms
1 ounce = 0.0625 pounds
For the purposes of this activity the template for a function has been provided. You have not yet covered functions in the course, but they are a way of reusing code. Like a Python script, a function can have zero or more parameters. In the code window you will see three functions defined as def convert_kg(value):, def convert_pounds(value):, and def convert_ounces(value):. Each function will have a block showing you where to place your code.
Answer:
Answered below.
Explanation:
def convert_kg(value){
ounces = value * 35.274
pounds = value * 2.20462
print("Kilograms to ounces: $ounces")
print("Kilograms to pounds: $pounds)
}
def convert_pounds(value){
kg = value * 0.453592
ounce = value * 16
print("pounds to kg; $kg")
print ("pounds to ounce; $ounce")
}
def convert_ounces(value){
kg = value * 0.0283
pounds = value * 0.0625
print ("ounces to kg; $kg")
print ("ounces to pounds; $pounds")
}
Write a recursive method called sumTo that accepts an integer parameter n and returns a real number representing the sum of the first n reciprocals. In other words, sumTo(n) returns (1 1/2 1/3 1/4 ... 1/n). For example, sumTo(2) should return 1.5. The method should return 0.0 if it is passed the value 0 and throw an IllegalArgumentException if it is passed a value less than 0.

Suppose Alice downloads a buggy browser that implements TLS incorrectly. The TLS specification says that, during the handshake, the browser should send a random 256-bit number RB. Instead of picking RB randomly the browser always sends all zeros. Describe an attack that is possible against this buggy browser and how to update the browser so that this attack is no longer feasible.
Solution :
It is given that Alice downloads the buggy browser which implements a TLS incorrectly. The specification of a TLS states that during a handshake, the browser sends a 256 bit number of RB randomly.
So in this case, a man-n-the-middle attack is possible. It can compromise the confidentiality of Alice. Updating the browser by visiting the website and checking its latest version of the browser or installing some other browser which has a more trust in the market for its security features.
Which option would allow you to watch an HD video, without delays in playback, on a computer with a Mac OS and a connection that has a lower bit rate? MPG QuickTime H.264 Flash Player
Answer:
H.264
Explanation:
A file type can be defined as the standard used to store digital data such as pictures, texts, videos, and audios. They all have unique file extension which determines the type of software program (application) to be used for opening a particular file and accessing its data e.g pictures (jpeg, png), texts (txt, docx, rtf), audios (mp3, acc), and videos (mp4, 3gp, avi, h.264, mkv).
Sometimes, computer users make the mistake of opening files with the wrong software application or program, this often leads to an error due to the incompatibility of the software application with the particular file.
H.265 is a high efficiency video codec (HEVC) and it's a standard video compression codec designed and developed to offer a better data compression, as an upgrade to the advanced video coding (AVC) standard.
Hence, the option or file extension (format) which would allow you to watch a high definition (HD) video, without delays in playback, on a computer with a Mac operating system (OS) and a connection that has a lower bit rate is the H.264 format.
In order to implement the classic DoS flood attack, the attacker must generate a sufficiently large volume of packets to exceed the capacity of the link to the target organization. Consider an attack using ICMP echo request (ping) packets that are 500 bytes in size (ignoring framing overhead). How many of these packets per second must the attacker send to flood a target organization using a 0.5-Mbps link
Answer:
131 packets
Explanation:
Given
W (link ) =0.5 M bits, and Ping packets ( P ) = 500bytes
To flood a target organization that has a bandwidth of W bits using a packet Mbits, you will require a W / P packet
P ( required ) = 500 * 8 = 4000 bits
therefore the W /P packet is calculated as
= 0.5 M bits / 4000 bits
given that : 1 M bits = 1,048,576 bits
0.5 M bits / 4000 bits= 131.07
hence approximately 131 packets/ sec is required to flood the target organization
# change amount as an integer input, and output the change using the fewest coins, one coin type per line. The coin types are Dollars, Quarters, Dimes, Nickels, and Pennies. Use singular and plural coin names as appropriate, like 1 Penny vs. 2 Pennies

coin_change =int(input())
def coin_change(cents):
if cents <= 0:
print( 'Zero cents.')
else:
quarter = cents // 25
dime = (cents % 25) //10
nickle = cents % 25 % 10 // 5
penny = cents % 5
print (coin_change )
# produces no output
Answer:
Explanation:
The Python code provided was not producing any output because you were never printing out the coin variables that you created. The following code adds the needed print statements using the right singular or plural coin name as needed.
cents = int(input())
def coin_change(cents):
if cents <= 0:
print('Zero cents.')
else:
quarter = cents // 25
dime = (cents % 25) // 10
nickle = cents % 25 % 10 // 5
penny = cents % 5
if quarter == 0 or quarter > 1:
print(str(quarter) + " quarters")
else:
print(str(quarter) + " quarter")
if dime == 0 or dime > 1:
print(str(dime) + " dimes")
else:
print(str(dime) + " dime")
if nickle == 0 or nickle > 1:
print(str(nickle) + " nickels")
else:
print(str(nickle) + " nickel")
if penny == 0 or penny > 1:
print(str(penny) + " pennies")
