For this activity, you will practice being both proactive and reactive to bugs. Both are necessary to get rid of errors in code.
Proactive:
Log in to REPL.it and open your Calculator program that you built in Unit 5.
In the index.js file, type and finish the following block of code that validates the input to make sure both are numbers (not letters or symbols):
try{
if (isNaN(…) || isNaN(…)){
throw …
}
else{
document.getElementById("answer").innerHTML = num1 + num2;
}
}
catch(e){
document.getElementById("answer")…
}
(Note: The || symbol is used in JavaScript to mean or . You can find this key to the left of the Z key if you’re using a PC or directly above the Enter key if you’re using a Mac.)
Add the finished code above to the correct place in your add() function. Make sure to delete this line since we moved it into the try block:
document.getElementById("answer").innerHTML = num1 + num2;
Paste the same code into the subtract() , multiply() , and divide() functions, making the necessary changes. Be careful with your divide() function since you already have an extra if else statement checking for a division by 0 mistake. (Hint: Cut and paste the entire if else statement inside the else block of your try statement.)
Test your program by typing in letters or symbols instead of numbers. Make sure you get the appropriate error message. (Note: The function is not supposed to check whether the text field is empty, only whether it contains non-numbers.)
When you are finished, share the link to your webpage with your teacher by clicking on the share button and copying the link.
Reactive:
The following Python program should print the sum of all the even numbers from 0 to 10 (inclusive), but it has two bugs:
x = 0
sum = 0
while x < 10:
sum = sum + x
x = x + 1
print(sum)
Complete a trace table and then write a sentence or two explaining what the errors are and how to fix them. You can choose whether to do the trace table by hand or on the computer. Turn in your trace table and explanation to your teacher.

Explanation:
5.19 LAB: Output values in a list below a user defined amount
Write a program that first gets a list of integers from input. The input begins with an integer indicating the number of integers that follow. Then, get the last value from the input, which indicates a threshold. Output all integers less than or equal to that last threshold value.
Ex: If the input is:
5
50
60
140
200
75
100
the output is:
50,60,75,
The 5 indicates that there are five integers in the list, namely 50, 60, 140, 200, and 75. The 100 indicates that the program should output all integers less than or equal to 100, so the program outputs 50, 60, and 75.
For coding simplicity, follow every output value by a comma, including the last one.
Such functionality is common on sites like Amazon, where a user can filter results.
Answer:
The program in Python is as follows:
n = int(input())
myList = []
for i in range(n):
num = int(input())
myList.append(num)
threshold = int(input())
for i in myList:
if i<= threshold:
print(i,end=", ")
Explanation:
This gets the number of inputs
n = int(input())
This creates an empty list
myList = []
This iterates through the number of inputs
for i in range(n):
For each iteration, this gets the input
num = int(input())
And appends the input to the list
myList.append(num)
This gets the threshold after the loop ends
threshold = int(input())
This iterates through the list
for i in myList:
Compare every element of the list to the threshold
if i<= threshold:
Print smaller or equal elements
print(i,end=", ")
The Python program below gets a list of integers, then filters that list based on a threshold value:
########################################################
# initialize the integer and output lists
integer_list = [ ]
output_list = [ ]
# first enter the number of integers that will follow
# and append it to integer list
qty = int(input("Enter the number of integers to follow: "))
integer_list.append(qty)
# next enter the number of integers and append them to integer list
for i in range(0, qty):
num = int(input("Enter an integer: "))
integer_list.append(num)
# finally enter the threshold value to be used to filter the integers
threshold = int(input("Enter the threshold value: "))
integer_list.append(threshold)
# filter the integers
for num in integer_list:
if num <= integer_list[-1]:
output_list.append(num)
# display the result
print("The values from { } that are less than or equal to { } are
{ }".format(integer_list[1:-1], integer_list[-1], output_list))
########################################################
The program first asks the user to enter the following:
The number of integers to be checkedThe integers themselvesThe threshold value to be used for filteringThe program next iterates over the integer list and filters the integers from index 1 to index -1(exclusive, since this is the threshold value) based on the element at index -1(the last element, the threshold value).
Each element that satisfies the filtering criterion (e <= threshold) is added to the output list and printed out later.

Answer:99
Explanation: Last summer, my family and I took a trip to Jamaica. My favorite part of the trip was when we went to a place called the Luminous Lagoon. We ate dinner and waited for the sun to go down. Then we boarded a boat and went out into the lagoon. That’s when the magic started.
At first we could not see very much in the darkness except for the stars in the sky. After a few minutes, however, I noticed some fish swimming in the water. They didn’t look like ordinary fish. These fish were glowing! Our guide explained that the glow came from tiny creatures in the water called dinoflagellates. These little animals are not visible to us, but their bodies produce light using something called bioluminescence, just like fireflies. There are so many of these creatures in Luminous Lagoon that the water around them seems to glow.
After our guide explained these facts to us, he told us to put our hands in the water. I was not sure if it would work, but I tried it. When I did, my hand looked like it belonged to a superhero! It was glowing bright blue. I hope someday I get to return to the Luminous Lagoon. The lights in the water were much more entertaining than the ones in the sky.
Problem:

The Greek prefix dinos- means “whirling” and the Latin root word flagellum means “whip”. What does dinoflagellate most likely mean as it is used in the passage?

To quit, a user types 'q'. To continue, a user types any other key. Which expression evaluates to true if a user should continue
Answer:
!(key == 'q')
Explanation:
Based on the description, the coded expression that would equate to this would be
!(key == 'q')
This piece of code basically states that "if key pressed is not equal to q", this is because the ! symbol represents "not" in programming. Meaning that whatever value the comparison outputs, it is swapped for the opposite. In this case, the user would press anything other than 'q' to continue, this would make the expression output False, but the ! operator makes it output True instead.

You are designing an application at work that transmits data records to another building in the same city. The data records are 500 bytes in length, and your application will send one record every 0.5 seconds
Is it more efficient to use a synchronous connection or an asynchronous connection? What speed transmission line is necessary to support either type of connection? Show all your work.
Solution :
It is given that an application is used to transmit a data record form one building to another building in the same city, The length of the data records is 500 bytes. and the speed is 0.5 second for each record.
a). So for this application, it is recommended to use a synchronous connection between the two building for data transfer as the rate data transfer is high and it will require a master configuration between the two.
b). In a synchronous connection, 500 bytes of data can be sent in a time of 0.5 sec for each data transfer. So for this the line of transmission can be either wired or wireless.

4. Interaction between seller and buyer is called___.
A. Demanding
B. Marketing
C. Transactions
D. Oppurtunity
Answer:
C. Transactions.
Explanation:
A transaction can be defined as a business process which typically involves the interchange of goods, financial assets, services and money between a seller and a buyer.
This ultimately implies that, any interaction between a seller and a buyer is called transactions.
For example, when a buyer (consumer) pays $5000 to purchase a brand new automobile from XYZ automobile and retail stores, this is referred to as a transaction.
Hence, a transaction is considered to have happened when it's measurable in terms of an amount of money (price) set by the seller.
Price can be defined as the amount of money that is required to be paid by a buyer (customer) to a seller (producer) in order to acquire goods and services. Thus, it refers to the amount of money a customer or consumer buying goods and services are willing to pay for the goods and services being offered. Also, the price of goods and services are primarily being set by the seller or service provider.

Write a method, findMax(), that takes in two integers and returns the largest value. Ex: If the program input is: 4 2 the method findMax() returns: 4 Note: Your program must define the method: public int findMax(int num1, int num2)
public int findMax(int num1, int num2){
if(num1 > num2){
return num1;
}
else {
return num2;
}
}
Explanation:The code has been written in Java and the following explains every part of the code.
i. Start with the method header:
public int findMax(int num1, int num2)
ii. Followed by a pair of curly braces representing the block for the method.
public int findMax(int num1, int num2){
}
iii. Within the block, write the statements to find out which is greater between num1 and num2
This is done with an if..else statement. To check if num1 is greater than num2, write the following within the block.
if(num1 > num2){
return num1;
}
else {
return num2;
}
The if block tests if num1 is greater than num2. If it is, then num1 will be returned.
The else block is executed only if num1 is not greater than num2. In this case, num2 will be returned since it is greater.
iv. Put all together
public int findMax(int num1, int num2){
if(num1 > num2){
return num1;
}
else {
return num2;
}
}

def area (width, height)
area = width * height
return area
boxlarea = area (5,2)
box2area = area (6)
What needs to change in order for the height in the area function to be 12 if a height is not specified when calling the function?
0 0 0 0
Add a height variable setting height =12 inside the function
Change the box2area line to box 2area = area (6,12)
Add a height variable setting height =12 before the function is declared
Change the def to def area (width, height = 12)
Answer:
D. Change the def to def area (width, height = 12)
Explanation:
Required
Update the function to set height to 12 when height is not passed
To do this, we simply update the def function to:
def area (width, height = 12)
So:
In boxlarea = area (5,2), the area will be calculated as:
[tex]area = 5 * 2 = 10[/tex]
In box2area = area (6), where height is not passed, the area will be calculated as:
[tex]area = 6 * 12 = 72[/tex]

Discuss at least 1 Microsoft Windows security features that could protect data?
Answer:
Virus & threat protection.
Explanation:
Monitor threats to your device, run scans, and get updates to help detect the latest threats.
One Microsoft Windows security feature that can help protect data is BitLocker Drive Encryption.
BitLocker is a full-disk encryption feature available in certain editions of Microsoft Windows, such as Windows 10 Pro and Enterprise. It provides protection for data stored on the system's hard drives or other storage devices.
By encrypting the entire drive, BitLocker helps safeguard the data against unauthorized access or theft, even if the physical drive is removed from the device. It uses strong encryption algorithms to convert the data into an unreadable format, ensuring that only authorized users with the appropriate encryption key or password can access and decrypt the data.
BitLocker also provides additional security features, such as pre-boot authentication, which requires users to enter a password or use a USB key to unlock the drive before the operating system loads. This prevents unauthorized users from accessing the encrypted data, even if they have physical access to the device.
Overall, BitLocker Drive Encryption is a powerful security feature in Microsoft Windows that can effectively protect data by encrypting entire drives and adding layers of authentication and protection against unauthorized access.

A .isLeapYear (1900)
B. isLeapYear (1984)
C. isLeapYear (2000)
D. isLeapYear (2001)
E. isLeapYear (2010)
Answer:
.isLeapYear (1900) will return an incorrect response
Explanation:
Given
The above method
Required
Which method call will give an incorrect response
(a) will return an incorrect response because 1900 is not a leap year.
When a year is divisible by 4, there are further checks to do before such year can be confirmed to be a leap year or not.
Since the method only checks for divisibility of 4, then it will return an incorrect response for years (e.g. 1900) that will pass the first check but will eventually fail further checks.
Hence, (a) answers the question;
