}
else{
myArr[i] = upc[i];
}
}
int sum = 0;
for (int x = 0; x < sizeof(myArr); ++x){
sum += (int)myArr[x] - '0';
}
if (sum% 10 == last){
cout<<"UPC number is valid";
}
else{
cout<<"Invalid UPC number.";
}
}
Explanation:
The UPC number in the c++ source code input must be 12 digits long for the rest of the code to execute. The code checks the validity of the number by comparing the reminder of the sum division with the last digit in the UPC number.
Assume that d is a double variable. Write an if statement that assigns d to the int variable i if the value in d is not larger than the maximum value for an int.
Answer:
That's because the value has reached the size limit of the int data type. ... you should use long rather than int , because long can store much larger numbers than int . If ... In other words, a float or double variable can't accurately represent 0.1 . ... If you're using Java to measure the size of your house, you'd need an electron ...

Consider a distributed denial of service (DDOS) attack, Assume the attacker has compromised a number of broadband connected computers to use as zombie systems. If the ISP provides a maximum uplink data rate of 512 Kbps in ADSL, what is the maximum number of 512-byte ICMP echo request (ping) packets a single zombie computer can send per second? How many such zombie systems would the attacker need to flood a target server in an organization that has
a. A Fast Ethernet.
b. A Gigabit Ethernet.
Answer:
A ) 200 Zombie systems
B ) 200 Zombie systems
Explanation:
maximum uplink data rate : 512 kbps = 512 * 1000 * 8 = 4096000 bits/sec
Determine the number of 512 byte ICMP echo packets = 512 * 8 = 4096 bits
hence the maximum number of 512-byte ICMP echo request (ping) packets a single zombie computer can send per second = 400 packets/sec
i.e. for 512kbps = 400 packets/sec
Determine the number of Zombie systems that the attacker will need to flood a target server
A) For a fast ethernet
A fast ethernet = 100 mbps
The number of Zombie systems needed = 1 zombie system * 200
and 1 zombie system = 512 kbps
therefore for a Fast ethernet the number of zombies systems needed = 200
B) For A Gigabit Ethernet
same as a fast ethernet system i.e. = 200

When you pass a double variable to a method, the method receives ______.a) a copy of the memory addressb) the reference of the variablec) the length of the variabled) a copy of the variablee) the binary memory address
Answer:
The answer is "Option d".
Explanation:
In this question the choice d, that is "a copy of the variable" is correct because the method takes a reference value or a copy of the variable in its parameter, the example of this question can be defined as follows:
void me2(double x)//defining a method me2 with a double parameter
{
//method body
}
double x = 35.655;//defining a double variable x
me2(x);//calling a method with passing the copy of th e variable
We wish to produce a graphic that is pleasing and easily readable. Suppose we
make the background color pink. What color text font should we use to make
the text most readable? Justify your answer.Assume that the color Pink is obtained by mixing equal amounts of Red and White. Use the RGB color model and assume that the amount of each primary color in the model is described in the interval [0 255]. Describe the color of the text font you would choose using these conventions.
Answer:
light color
Explanation:
When we will mix equal amounts or equal quantities of the color red and the color white, we will get the color reddish pink. It is popularly called as the SOFT RED and the color code of this color is RGB (255, 128, 128).
Since, red color + white color = 0.5 RGB(255, 0, 0) + 0.5RGB(255, 255, 255)
= RGB (255, 128, 128)
According to me, the color white will best suit as the text color that can be used for a background having RGB(255, 128, 128). Because the color looks more red and not that pink, so it wise to use a light tone color for the natural reading purpose. Hence, it will not give strain to the eyes.

Explanation:
If process P0 is switched to process P1, state for P0 will be saved into ____, and state from ___ will be reloaded.
Answer:
1. PCB0
2. PCB1
Explanation:
Given that PCB is often referred to as Process Control Block, is a form of data structure that is applicable and utilized by the computer operating systems to store all the information concerning a process.
This process is carried out in a way that when Process P0 is initialized, the operating system established a related process that takes the computer processing unit from Process P0 and allocates it to Process P1, the Operating System, in turn, will save P0's PCB, and then reload P1's PCB.
Hence, If process P0 is switched to process P1, the state for P0 will be saved into "PCB0" and the state from "PCB1" will be reloaded.

Answer: Nothing should be done.
Explanation:
Group Policy helps in the provision of a centralized management of operating systems, and applications. It should be noted that a group policy object (GPO) is simply referred to as the configurations involving the group policy.
Nothing should be done to manage the GPO created. When the permission to create a GPO has been given to someone, it means that they can also manage the GPO therefore, nothing needs to be done anymore.

One of the systems analysts on the project team thought that he did a good job of designing the company’s tech support webpage, but his supervisor isn’t so sure. His supervisor is concerned that the design is very similar to a page used by the company’s major competitor, and she asked him whether he had used any HTML code from that site in his design. Although the analyst didn’t copy any of the code, he did examine it in his web browser to see how they handled some design issues. The supervisor asked the analyst to investigate webpage copyright issues and report back to her. In his research, the analyst learned that outright copying would be a copyright violation, but merely viewing other sites to get design ideas would be permissible. What is not so clear is the gray area in the middle. The analyst asked you, as a friend, for your opinion on this question: Even if no actual copying is involved, are there ethical constraints on how far you should go in using the creative work of others? How would you answer?
Explanation:
Although the system analyst only viewed the HTML code as a major competitor not outrightly copying their code, however, since there are relatively few legal frameworks on this matter, it important to note some ethical issues or constraints that may arise:
Copying the design pattern of the competitors' webpage may result in legal fillings by the competitors which may claim the other company stole its intellectual designs without permission.Such actions may result in other competitors carrying out the same strategy on the company.how to create diagram that demonstrates the step

Define a function pyramid_volume with parameters base_length, base_width, and pyramid_height, that returns the volume of a pyramid with a rectangular base.
Answer:
Define a function pyramid_volume with parameters base_length, base_width, and pyramid_height, that returns the volume of a pyramid with a rectangular base.
Explanation:
thats all you said
In python 3.8:
def pyramid_volume(base_length, base_width, pyramid_height):
return round((base_length*base_width*pyramid_height)/3,2)
print(pyramid_volume(1,1,2))
I used the round function to round the volume to 2 decimal places. You can change this if you need more or less precision. I hope this helps!

correct answer edge 2020
# the main part of your program that calls the function poem() userWord and rhymeWord. Hence, option C is correct.
What is rhymeWord?Rhyming words all have the same last consonant. Simply put, it is the repetition of similar sounds. When two words have similar sounds, usually those that follow the final stressed syllable of each word, the words are said to rhyme. Cat-hat, rotten-forgotten, and heard-bird are some examples of words that rhyme; they all have similar sounds after the final stressed syllable.
If the last sounds of two or more words are the same or similar, then the words will rhyme. Some words that rhyme are goat, boat, moat, float, and coat. To determine whether two words rhyme, use your ears to listen while you speak the words. If two words have a similar or matching sound, they rhyme.
Thus, option C is correct.

Which statement is true? A. Pseudocode uses shapes such as rectangles and diamonds to plan a program. B. You only use comments for pseudo code. C. A flowchart uses comments that can be kept as a permanent part of a program. D. A comment line begins with # Please hurry also you can only choose one answer so idk which one thank you
Answer:
D) A comment line begins with #
Explanation:
Comments are used in programming to explain what a line or block of code is doing.
It helps the programmer easily remember what their code was about when they come back to it having left it for a while.
Also comments help other programmers understand code written by one programmer.
A comment or an in-line comment usually begins with #. That way the computer skips it and doesn't regard it as a line of code.
Answer: D. A comment line begins with #.
Explanation:
In the text, it stated, "The easiest way to add a comment is to start the line with the pound sign (#)."
(Comments are notes that allow you to write anything without affecting the code itself. Comments can be utilized to indicate when and how you later changed a program, and provide a description of the changes.)

Clyde Clerk is reviewing his firm’s expense reimbursement policies with the new salesperson, Trav Farr. "Our reimbursement policies depend on the situation. You see, first we determine if it is a local trip. If it is, we only pay mileage of 18.5 cents a mile. If the trip was a one-day trip, we pay mileage and then check the times of departure and return. To be reimbursed for breakfast, you must leave by 7:00 a.m., lunch by 11:00 a.m., and have dinner by 5:00 p.m. To receive reimbursement for breakfast, you must return later than 10:00 a.m., lunch later than 2:00 p.m., and have dinner by 7:00 p.m. On a trip lasting more than one day, we allow hotel, taxi, and airfare, as well as meal allowances. The same times apply for meal expenses." Write structured English for Clyde’s narrative of the reimbursement policies. Draw a decision tree.
Answer:
The answer is described in the image.
Explanation:
The firm is responsible for all expenses made by it's employees, so for a local trip, the cost of gas relative to the mileage covered during the journey is paid for ( 18 cents per mileage).
If it is not a local trip, then it is a one-day trip, so the firm pays for the mileage and the cost of the meals not taken in the company, which depends on the departure and return/arrival time. If the departure and return time is 7am to 10am, the employee is paid for breakfast, if the departure and return is 11am to 2pm then the employee is paid for lunch, and for dinner, 5pm to 7pm.
