The following is written in Java. It creates a while loop that requests price from the user and goes adjusting the quantity and subtotal as more prices are added. If 0 is entered it breaks the loop and outputs the quantity, subtotal, tax, and grand total to the user.

       Scanner in = new Scanner(System.in);

       int quantity = 0;

Answer:

POP

Explanation:

The application layer protocol that is been used here is POP, given that you issued a transmission to the socket on you LAN: 10.1.145:110.  and you use a standard port designation

Reason:

110 ( port number ) represents a POP3 process that is always used in a TCP/IP network , and the socket address started with an IP address as well. hence we can say that the application layer protocol is POP

Which XXX declares a student's name.

public class Student {

   XXX

   private double myGPA;  

   private int myID;

   public int getID() {

        return myID;

   }

}

Group of answer choices

a. String myName;

b. public String myName;

c. private myName;

d. private String myName;

private String myName;

To declare a student's name, the following should be noted.

i. The name of the student is of type String

ii. Since all of the instance variables (myGPA and myID) have a private access modifier, then myName (which is the variable name used to declare the student's name) should be no exception. In other words, the student's name should also have a private access.

Therefore, XXX which declares a student's name should be written as

private String myName;

Option (a) would have been a correct option if it had the private keyword

Option (b) is not the correct option because it has a public access rather than a private access.

Option (c) is not a valid syntax since, although it has a private access, the data type of the variable myName is not specified.

Option (d) is the correct option.

Answer:

The function in Python is as follows:

def reverse(inputstr):  

   outputstr = ""

   for i in inputstr:

       outputstr = i + outputstr

   return outputstr

Explanation:

This defines the function

def reverse(inputstr):

This initializes the output string

   outputstr = ""

This iterates through the input string

   for i in inputstr:

This generates the output string by reversing the input string

       outputstr = i + outputstr

This returns the reversed string

   return outputstr

   Vowels(userString);

   return 0;

}

void Vowels(string userString)

{

   char currentChar;

   //variables to hold the number of instances of each vowel

   int a = 0, e = 0, i = 0, o = 0, u = 0;  

   for (int x = 0; x < userString.length(); x++)  

   {

       currentChar = userString.at(x);

       switch (currentChar)  

       {

           case 'a':

               a += 1;

               break;

           case 'e':

               e += 1;

               break;

           case 'o':

               o += 1;

               break;

           case 'u':

               u += 1;

               break;

           default:

               break;

       }

   }

   // to print no of times a vowels appears in the string

   cout << "Out of the " << userString.length() << " characters you entered." << endl;

   cout << "Letter a = " << a << " times" << endl;

   cout << "Letter e = " << e << " times" << endl;

   cout << "Letter i = " << i << " times" << endl;

Answer:

The modified program in Python is as follows:

triangle_char = input('Enter a character:\n')

triangle_height = int(input('Enter triangle height:\n'))  

for i in range(triangle_height):

   print(triangle_char * (i+1))

Explanation:

This gets the character from the user

triangle_char = input('Enter a character:\n')

This gets the height of the triangle from the user

triangle_height = int(input('Enter triangle height:\n'))  

This iterates through the height

for i in range(triangle_height):

This prints extra characters up to the height of the triangle

   print(triangle_char * (i+1))

Here's the modified program that incorporates the requested changes:

python

Copy code

triangle_char = input('Enter a character:\n')

triangle_height = int(input('Enter triangle height:\n'))

print('')

for i in range(1, triangle_height + 1):

   line = triangle_char * i + ' ' * (triangle_height - i)

   print(line)

This program uses a loop to iterate from 1 to triangle_height. In each iteration, it creates a line by concatenating triangle_char repeated i times with spaces (' ') repeated (triangle_height - i) times. The resulting line is then printed.

For example, if the user enters % as the character and 5 as the height, the output will be to make sure to maintain the indentation properly in your code for it to work correctly.

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?
