Answers

Answer:

This is an ongoing battle of neutrality between the Carriers and Websites.

The government can primarily be responsible for protecting the rights of the users of the websites. However it is also important for the government to ensure equality of rights to carriers and websites, at times carriers are not provided much attention and are often neglected but they play an important role and therefore should have equal rights.

Write a method for the Invitation class that accepts a parameter and uses it to update the address for the event.

Answers

Answer:

public class Invitation {

 private String hostname;

 private String address;

  public Invitation(String n, String a) {  // constructor that accepts two strings.

   hostname = n;

   address = a;

 }

  public String getHostname() {

   return hostname;

 }

 public void setAddress(String a) {

   address = a;

 }  

 public String invite(String guest) {

   return "Hello" +guest+ ", you are invited to my party at " +address+". "+hostname+".";

 }

 public Invitation(String host, String address) {

   this.address = address;

   this.hostname = host;

 }

}

Explanation:

The Java program defines a class called "Invitation". The class constructor has two string arguments or parameters for the host of the event and the address. The invite method is used to generate the string invite message with the name of the guest as the argument. Use the "setAddress" method to set a new location of the event and the "getHostname" to get the name of the event host.

To implement this task, I will be using Native Android code with Kotlin and the recent JetPack Compose Library, you will need Android studio to be able to run this code

//To mange the UI State we will be using view-model

class InviteViewModel: ViewModel() {

  // LiveData holds state which is observed by the UI

  // (state flows down from ViewModel)

  private val _name = MutableLiveData("")

  val name: LiveData<String> = _name

  // onNameChanged is an event we're defining that the UI can invoke

  // (events flow up from UI)

  fun Invite (newName: String) {

      _name.value = newName

  }

}

//Here is the MainActivity class where the code will run from

class Invitation : AppCompatActivity() {

  private val inviteViewModel by viewModels<InviteViewModel>()

  override fun onCreate(savedInstanceState: Bundle?) {

      /* ... */

      binding.textInput.doAfterTextChanged {

          inviteViewModel.onNameChanged(it.toString())

A software company used to run an algorithm sequentially on one server. As more users start using their app, the company decided to rewrite the program to be parallel. It is now run on four separate servers instead of one Thanks to the use of a parallel algorithm, the same process that used to take 40 minutes to run now only requires 20 minutes. The company is considering purchasing additional computers to decrease the time the program runs even further. Which of the following best describes the impacts of running the parallel algorithm on an even larger number of computers.

a. The algorithm will likely require more time since it is now being run sequentially on more computers.
b. The algorithm will likely require the same amount of time to run because it is processing the same amount of data.
c. The algorithm will likely require less time to run though the improvements in efficiency will not be as significant as before.
d. The algorithm is unlikely to still run since parallel algorithms are not designed to scale to additional computers

Modify your previous exercise to determine if the user can ride a rollercoaster. To ride the rollercoaster, you must be at least 42 inches tall. You must also be at least 9 years old. Ask the user how tall and how old they are. Use ONE if-else to determine if the user can ride the rollercoaster. Note how much cleaner this is and how much less repetition this method has.

Answers

Answer:

In Python:

age = int(input("How old are you? "))

height = float(input("How tall are you (inches)? "))

if age>=9 and height >= 42:

    print("You can ride the roller coaster")

else:

    print("You ca'nt ride the roller coaster")

Explanation:

The code segment of the "previous exercise" is not given; so, I rewrite the program from scratch using python.

And using the solution I provided, you'll have an idea of how to write the expected code If the "previous exercise" is not written in python,

This line prompts user for age

age = int(input("How old are you? "))

This line prompts user for height

height = float(input("How tall are you (inches)? "))

This checks if user is at least 9 years old and at least 42 inches tall

if age>=9 and height >= 42:

If true, the user gets to ride the roller coaster

    print("You can ride the roller coaster")

else:

If otherwise, the user will not ride the roller coaster

    print("You ca'nt ride the roller coaster")

the cause of french revolution and anayze the reason for significane out come

Answers

Answer:

The French Revolution, which occurred from 1789 to 1799, was a time in French history when republicans overthrew the monarchy and the Roman Catholic Church went through a period of fundamental restructuring in France. While France swapped back and forth between republic, empire and kingship for 75 years following the fall of the First Republic into the hands of Napoleon Bonaparte, the revolution nevertheless marked the end of the ancient regime and put its followers in the shadows of the imagination of the French people.

The French Revolution began as a protest by the aristocrats against Louis XVI, the king of France and his absolute monarchy, and evolved as a major revolution that changed Europe's history and outlook.

A group called the Girondins, from the Bordeaux area, came to power but was opposed by the Jacobins group. The Jacobins were replaced by the Directoire, a middle-class group that had merged with the Girondins, and a new moderate government was formed. They came to power in 1794 but by 1799 they were considered corrupt and Napoleon took over. Napoleon came to the power with the support of the army and ruled as a tyrant. It was the need for stability and the disposition of the corrupt revolution that made the people willing to accept Napoleon even though he was a dictator. Napoleon brought a new order but many old institutions were also re-established.

Answers

Answer:

Explanate The social, political, and economic causes of the American Revolution inevitably helped shape the country we live in today. A social cause that occurred was the disagreement between America and Britain and how poorly they were treated. A political cause that occurred was the implantation of legislatures on the colonies ion:

Inevitably, the social, political, and economic factors that led to the American Revolution influenced the nation we live in today. The conflict between America and Britain and how horribly they were treated were societal causes.

What is the French Revolution?

The imposition of taxes on the colonies, which they refused to pay, is one of the economic and intellectual roots of the American Revolution. The primary objective of taxation was to pay back the debt the colonists owed as a result of the conflict.

The idea behind this revolt was that an unbalanced government was being caused by crooked politics. Poor economic policies that led to bankruptcy and the lavish spending of the French royal family, which resulted in the imposition of exorbitant taxes on the populace, are the economic and ideological reasons for the French Revolutions.

The Enlightenment, which was influenced by the British political system, was the ideological cause.

Therefore, the increasing imperialist demand from the west and Japan as well as the desire to see a united China were the main drivers behind the economic and ideological causes of the Chinese revolutions.

Write a function that accepts two pointers; one to the first element and one to the last element of an integer array. The function returns how many numbers are negative in the array. Use only pointer notation.

Answers

Answer:

The code to this question can be defined as follows:

int count(int *first, int *last)//defining a method count that accepts two integer pointer    

{

   int c=0;//defining integer variable c

   while (first <= last)//defining a while loop that counts first to last value  

   {

       if (*first < 0)//use if block to check negative value

           c++;//increment variable value

       first++;//increment first parameter value

   }

   return c;//return c value

}

Explanation:

In this code, a method "count" is declared that accepts two pointer variable "first and last" as the parameter, inside the method an integer variable "c", and a while loop is declared that counts values, and inside this an if block is used that counts the negative value and increment its value, and also increments the first parameter value, and return c value.

_________ is a variety of mechanisms used to assure the integrity of a data unit or stream of data units.

Answers

Answer:

Data integrity.

Explanation:

Data integrity is a variety of mechanisms used to assure the integrity of a data unit or stream of data units.

In Computer programming, integrity constraints can be defined as a set of standard rules that ensures quality information and database are maintained.

Basically, there are four (4) types of integrity constraints and these are;

1. Key constraints.

2. Domain constraints.

3. Entity integrity constraints.

4. Referential integrity constraints.

For example, when a foreign key in Table A points to the primary key of Table B, according to the referential integrity constraints, all the value of the foreign key in Table A must be null or match the primary key in Table B.

Hence, any integrity constraint ensures that the relationship between the data in a table is consistent and valid.

Just as the name suggests, it involves a server (ie a computer that serves or allows the exchange of data between computers) allowing several different Operating systems (OS) to have their own different configurations.

The fact that the various operating systems will need their individual system configuration presents difficulties and challenges. Also, as the partitioning of the hardware resources has to be done, the server computer memory may become overused.
