Answer: trojan horse virus

Explanation:A trojan horse is a non-replicating program that looks legitimate, but it is actually used to perform malicious and illicit activities when launched. Attackers use trojan horses to steal a user's

personal information like password information, or they may simply use it to destroy programs or data on the hard disk.

Answers:

What is the index of the last element in the array? stArr1.length()-1

This prints the names in order. How would I print every other value? Change line 4 to: index = index +2

Change line 7 to: i < names.length

Problem 2 Write a method that (a) returns an int[] , (b) takes in two sorted arrays (in descending order) and (c) returns an int

Galina-37 [17]

Answer:

Following are the Program in the Java Programming Language.

//define class

public class Main

{

//define function to merge and sort array

public static int[] sort_Array(int[] a, int[] b)

{

//set integer variable and initialize values

int x = 0, y = 0, k = 0, num = 0;

int n = a.length;

int n1 = b.length;

//set integer type array

int[] ar = new int[n+n1];

//set while loop

while (x<n && y <n1)

{

num++;

//set if conditional statement

if (a[x] > b[y])

ar[k++] = a[x++];

else

ar[k++] = b[y++];

num++;

}

//set the while loop

while (x < n)

{

num++;

ar[k++] = a[x++];

}

//set the while loop

while (y < n1)

{

num++;

ar[k++] = b[y++];

}

//print the total compares done

System.out.println("Number of compares done: " + n);

//return array

return ar;

}

//define main method

public static void main(String[] args)

{

//declaration and the initialization of array

int[] a = new int[]{18,16, 15, 6, 2};

int[] b = new int[]{13, 12, 11, 7, 1};

int[] ar;

//call function

ar = sort_Array(a, b);

//print message

System.out.println("\nThe resultant array is: \n");

//set for loop to print array

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

{

System.out.print(ar[x] + " ");

}

<u>Output</u>:

Number of compares done: 5

The resultant array is:

18 16 15 13 12 11 7 6 2 1

Explanation:

Here, we define a class "Main" inside the class, define a function "sort_Array()"and pass two integer type array argument "a" and "b".

Set four integer type variables "x", "y", "k", and "num" and initialize them to 0.
Set two integer type array "n", "n1" and initialize them the length of the array then, set integer type array variable "ar".
Set the while loop then, set if conditional statement then, agin set while loop to sort array in descending order.
Then, print the number of compares and return the value of the variable "ar".

Finally, define the main method inside it, we set two integer type array variable and initialize elements in them then, set the for loop to print the sorted elements of the array.

Write a program that creates a dictionary containing the U.S. states as keys and their abbreviations as values. The program shou

AleksandrR [38]

Answer:

Explanation:

The following program is written in Python. It creates a loop that keeps creating a random number to randomly choose a State abbreviation from the dictionary. Then it asks the user what the state is. If the user gets the answer correct it prints out "Correct" and adds 1 point to the correct variables. Otherwise it prints "Incorrect" and adds 1 point to the incorrect variable. Finally, printing out the final amount of correct and incorrect responses. The program was tested and the output can be seen below.

import random

states = {"AL":"Alabama","AK":"Alaska","AZ":"Arizona","AR":"Arkansas","CA":"California","CO":"Colorado","CT":"Connecticut","DE":"Delaware","FL":"Florida","GA":"Georgia","HI":"Hawaii","ID":"Idaho","IL":"Illinois","IN":"Indiana","IA":"Iowa","KS":"Kansas","KY":"Kentucky","LA":"Louisiana","ME":"Maine","MD":"Maryland","MA":"Massachusetts","MI":"Michigan","MN":"Minnesota","MS":"Mississippi","MO":"Missouri","MT":"Montana","NE":"Nebraska","NV":"Nevada","NH":"New Hampshire","NJ":"New Jersey","NM":"New Mexico","NY":"New York","NC":"North Carolina","ND":"North Dakota","OH":"Ohio","OK":"Oklahoma","OR":"Oregon","PA":"Pennsylvania","RI":"Rhode Island","SC":"South Carolina","SD":"South Dakota","TN":"Tennessee","TX":"Texas","UT":"Utah","VT":"Vermont","VA":"Virginia","WA":"Washington","WV":"West Virginia","WI":"Wisconsin","WY":"Wyoming"}

keys_list = list(states)

correct = 0

incorrect = 0

while True:

randNum = random.randint(0, 49)

abbr = keys_list[randNum]

answer = input("Enter The State name of " + abbr + ": ")

if answer.lower() == states[abbr].lower():

print("Correct")

correct += 1

else:

print("Incorrect")

incorrect += 1

again = input("Play again? y/n ")

if again.lower() == 'n':

break

print("Correct: " + str(correct))

print("Incorrect: " + str(incorrect))
