Answer:

Extended authentication

Explanation:

Xauth = Extended authentication

An extended authentication can cause security to be increased because it requires the user to enter a username and password. These details would then be authenticated at the internal database of the controller. This extension is an ipsec extension which would enable VPN users to enter a username and password. These details would be required of the user while trying to connect and they would be checked against the login details registered by such a user.

Answer:

The correct option is A True

Explanation:

Arrays are implemented to store sevaral variables of the same type as a single array object in java for example. The arrays therefore acts as a container that can store several variables of the same type hence preventing the need to declare those variables seperately thus giving more code efficiency and better storage space management.

Complete Question:

Write a program that reads a person's first and last names, separated by a space. Then the program outputs last name, comma, first name. End with newline.  

Example output if the input is: Maya Jones

Jones, Maya

In C++

Answer:

The program written in C++ is as follows

#include<iostream>

using namespace std;

int main(){

string lname, fname;

cout<<"First name: ";

cin>>fname;

cout<<"Last name: ";

cin>>lname;

cout<<lname<<", "<<fname;

return 0;

}

Explanation:

This line declares lname, fname as string to get the user's last name and first name, respectively

string lname, fname;

This line prompts the user for first name

cout<<"First name: ";

This line gets the user first name

cin>>fname;

This line prompts the user for last name

cout<<"Last name: ";

This line gets the user last name

cin>>lname;

This line prints the desired output

cout<<lname<<", "<<fname;

The program in Python is

person_name = input("Enter your first name and last name separated

                           by space: ")

split_names = person_name.split( )

first_name = split_names[0]

last_name = split_names[1]

print(last_name + ", " + first_name)

The first line of the program requests the first and last names as a single string, separated by a space.

The next line splits the name into first and last names

Finally, the print statement displays the names reversed, but separated with a comma

Answer:

Here is for loop that sets sumExtra to the total extra credit received. I am writing a program in C++

for(i = 0; i <= testGrades.size() - 1; i++){

  if(testGrades.at(i) > 100){

      sumExtra = sumExtra + (testGrades.at(i) - 100);   } }

Explanation:

The complete program is:

#include <iostream> //to use input output functions

#include <vector> //to use vectors

using namespace std; //to identify objects like cin cout

int main() { //start of main function

const int NUM_VALS = 4; // sets the value of NUM_VALS as a constant to 4

vector<int> testGrades(NUM_VALS); // initialize the vector of int (integer) type

int i = 0; // i is initialzed to 0

int sumExtra = 0; //stores the total extra credit

testGrades.at(0) = 101; //sets 101 at first position in vector

testGrades.at(1) = 83; //sets value 83 at second position

testGrades.at(2) = 107; //sets value 107 at third position

testGrades.at(3) = 90; //sets value 90 at fourth position

for(i = 0; i <= testGrades.size() -1; i++){ //loop iterate through each value of in a vector testGrades

  if(testGrades.at(i) > 100){ // if the value in a vector exceeds 100

      sumExtra = sumExtra + (testGrades.at(i) - 100);   } } //computes total extra credit

cout << "sumExtra: " << sumExtra << endl;} //displays the value of computed total extra credit in output

The loop works as follows:

In the first iteration the value of vector testGrades at(i) is at(0) = 101.

if statement checks if this value/element is greater than 100. This is true as 101 > 100. So sumExtra = sumExtra + (testGrades.at(i) - 100); statement is executed in which 100 is subtracted from that element and the result is added to the sumExtra. sumExtra is initialized to 0 so the value of sumExtra becomes: 0+ 101 - 100= 1 So the value of sumExtra = 1

In the second iteration the value of i = 1 and it is positioned at 2nd value of vector testGrades i.e. 83. Then if statement checks if this value/element is greater than 100. This is false as 83 < 100. So the value of sumExtra = 1

In the third iteration the value of i = 2 and it is positioned at 3rd value of vector testGrades i.e. 107. Then if statement checks if this value/element is greater than 100. This is true as 107 > 100.

sumExtra = sumExtra + (testGrades.at(i) - 100); statement is executed in which 100 is subtracted from that element and the result is added to the sumExtra

sumExtra is 1 so the value of sumExtra becomes: 1+ 107 - 100= 8 So the value of sumExtra = 8

In fourth iteration  the value of i = 3 and it is positioned at 4th value of testGrades vector i.e. 90. Then the if statement checks if this element is greater than 100. This is false as 90 < 100. So the value of sumExtra remains 8.  

Finally the loop breaks as the value of i becomes 4. So the output is 8.

Answer:

sumExtra = 0;

   for (i = 0; i < NUM_VALS; ++i) {

     if (testGrades[i] >= 101) {

     sumExtra += (testGrades[i] - 100);

     }

   }

   cout << "sumExtra: " << sumExtra << endl;

Group of answer choices

A. Wildcard

B. The Tab key

C. Regular expressions

D. The Escape key

Answer:

B. The Tab key

Explanation:

In this scenario, You are entering command that operates on a file. The path to the file is lengthy and confusing and you are afraid that you will misspell part of it. You can help yourself out via the use of the Tab key.

When working with the command line prompt (cmd) on a Windows, Unix or Linux computer, typing file paths is sometimes difficult or considered to be a burden because they are lengthy (too long) and perhaps confusing to the user. To help yourself out, you can always use the "Tab key" to autocomplete names of directories or file paths in an alphabetical order, while in the command line.

Additionally, pressing the "Tab key" continuously while in the command line would cycle or toggle all available commands in an alphabetical order.

Answer:  d. colors = {"red", "orange", "yellow", "green", "blue", "indigo", "violet"}

Explanation:

We use "{}" to write a set in it.

Also, the names of the colors are strings so we use inverted commas ("") to express them.

So, the set named colors that contains the 7 colors in a rainbow will be:

colors = {"red", "orange", "yellow", "green", "blue", "indigo", "violet"}

Hence, the correct option is d.

Here is the copy assignment operator for CarCounter:

CarCounter& CarCounter::operator=(const CarCounter& objToCopy) {

carCount = objToCopy.carCount;

return *this;  }

The syntax for copy assignment operator is:

ClassName& ClassName :: operator= ( ClassName& object_name)

In the above chunk of code class name Is CarCounter and object name is objToCopy.

Assignment operator = is called which assigns objToCopy.carCount to the new objects's carCount.

This operator basically is called when an object which is already initialized is assigned a new value from another current object.

Then return *this returns the reference to the calling object

Explanation:

The complete program is:

#include <iostream>  //to use input output functions

using namespace std;   //to access objects like cin cout

class CarCounter {  //class name

public:  // public member functions of class CarCounter

CarCounter();  //constructor of CarCounter

CarCounter& operator=(const CarCounter& objToCopy);  //copy assignment operator for CarCounter

void SetCarCount(const int setVal) {  //mutator method to set the car count value

carCount = setVal;  } //set carCount so setVal

int GetCarCount() const {  //accessor method to get carCount

return carCount;  }  

private:  //private data member of class

int carCount;  };    // private data field of CarCounter

CarCounter::CarCounter() {  //constructor

carCount = 0;  //intializes the value of carCount in constructor

return; }  

// FIXME write copy assignment operator  

CarCounter& CarCounter::operator=(const CarCounter& objToCopy){

/* copy assignment operator for CarCounter that assigns objToCopy.carCount to the new objects's carCount, then returns *this */

carCount = objToCopy.carCount;

return *this;}  

int main() {  //start of main() function

CarCounter frontParkingLot;  // creates CarCounter object

CarCounter backParkingLot;   // creates CarCounter object

frontParkingLot.SetCarCount(12);  // calls SetCarCount method using object frontParkingLot to set the value of carCount to 12

backParkingLot = frontParkingLot;  //assigns value of frontParkingLot to backParkingLot

cout << "Cars counted: " << backParkingLot.GetCarCount();  //calls accessor GetCarCount method to get the value of carCount and display it in output

return 0;  }

The output of this program is:

Cars counted = 12

I would like to stay anonymous while criticizing the current government. As there have been many cases when people who wrote against the government's decisions were caught by the police.

So I would prefer to stay anonymous while commenting on various government policies. My friends would know about it because I share my posts only with them.

The government can know about my identity by ordering the social networking site to reveal it.

One scenario in which you can act ethically but still remain anonymous when using the internet could be to guarantee your freedom of expression on a certain subject, sharing your ideas in the way you think is ideal for the situation.

It is protected by the US Supreme Court under the First Amendment, but its protection is balanced, that is, anonymity on the internet can be dissolved and the user can be found if the use of this function occurs to commit cyber crimes.

Therefore, it is essential that every individual action on the internet and outside of it is based on ethics and legality, so that there is an orderly and positive society for all citizens.

Explanation:

Since there are 5 vowels, you'd need at least 3 bits to number them. 2 bits give you 2²=4 possibilities, which is 1 short. 3 bits give you 2³=8 possibilities, which fits 5 easily.

The term "bit" means binary digit, and it is used to represent data in a computer system.  

The number of character an n-bit computer can hold is [tex]2^n[/tex]

So, a 2-bit computer can hold a maximum of:

[tex]Max = 2^2[/tex]

[tex]Max = 4[/tex]

i.e. A 2-bit computer can hold a maximum of 4 characters.

The English language vowel are 5 (i.e. letters a, e, i, o and u).

5 is greater than the maximum number of characters the 2-bit computer can hold (i.e. 5 > 4)

Hence, two bits will not be enough to hold each vowel in the English language.

Explanation:

Int, Float, Long and Boolean are commonly used data types in programming languages. Of these data types, the Boolean data type, named after George Boole, does not represent a numerical value. Rather it has one of two possible values, True and False. These values represent the two truth values of logic and Boolean algebra.

The Boolean data type is basically associated with conditional statements which specifies different actions to be taken depending on whether the Boolean condition evaluates to true or false. Therefore it influences the control flow of a program.
