B. REPEAT UNTIL
C. DO
D. None of the other answers are correct
Answer:
B.
Explanation:
Based on the information provided within the question it can be said that the loop that should be used is a repeat until loop. This is because this loop will continue cycling until a certain condition is met. In this situation, the loop breakout condition would be the output of the final element in the last column and row of the two-dimensional array.
Final answer:
To output the contents of a fully-filled two-dimensional array using pseudocode, you can use a nested FOR loop. The outer loop will iterate over the rows of the array, while the inner loop will iterate over the columns within each row.
Explanation:
To output the contents of a fully-filled two-dimensional array using pseudocode, you can use a nested FOR loop. The outer loop will iterate over the rows of the array, while the inner loop will iterate over the columns within each row. Here's an example:
FOR row = 1 TO number_of_rows
FOR column = 1 TO number_of_columns
OUTPUT array[row][column]
END FOR
END FOR
In this pseudocode, number_of_rows and number_of_columns represent the dimensions of the array. The OUTPUT statement is used to display the value of each element in the array.

Following are the program in the Python Programming Language:
def check_nums(length): #define function
my_lst=[] #set list type variable
n=0 #set integer type variable
while(length[n] != 7): #set the while loop
my_lst.append(length[n]) #append liat in my_lst
n+=1 #increament in n
if(len(length)==n): #set if condition
break #break the loop
return my_lst #return the list
l=[4,6,2,55,16,7,81] #set list variable and assign list init
print(check_nums(l)) #call and print the function

Normally any bank will not ask end user about login details such user id, password, pin number in email. So bob as think and before responding the mail. Moreover this type email to be considered as hacker email, who want to access the bob accounts and do access his account and steal money from bob accounts.
Luckily bob contacted bank to stop further hackers not to his accounts. Since it is grammar mistake bob understood it is hackers who asking bob user id and password.
Bob has prompted these type of mails are called phishing emails. Better to avoid it.
Final answer:
The attack described in the question is known as phishing, which is a deceitful attempt to obtain sensitive information like passwords via email by pretending to be a legitimate entity. Spear phishing is a more targeted form of phishing. Both are examples of social engineering techniques used by cybercriminals.
Explanation:
The type of attack described in this scenario is known as phishing. Phishing is a form of cyber attack where attackers use fraudulent emails that appear to come from legitimate sources, such as a bank, to trick individuals into providing sensitive information like passwords and user IDs. The method often involves poor grammar and incorrect spelling, and banks will never ask for such sensitive information via email.
Sometimes phishing attempts can be more targeted and sophisticated, this is called spear phishing, which involves emails personalized with information known about the individual to increase the chances of success.

The process of recording an actor’s movement digitally for the purpose of animating a digital character in a movie is called Realistic Animation Motion Capture CGI (Computer Generated Imagery) Performance Animation
Answer:
It is called Motion Capture.
Explanation:
Motion capture it's a widely used technology that allows us to record (or capture) the movements of a real person, and convert them to a digital environment.
It can be used in the development of video games when facial expressions or realistic movements are needed to bring fictional characters to life, motion sensors are used on a real person, and the person displays the necessary emotions, movements or expressions that are later digitally adapted to the 3D character.
Motion capture was one of the main techniques used to bring the famous Thanos, the famous Avenger's villain to life. Josh Brolin, the actor, would perform almost every scene wearing a specialized suit to capture the movements and facial expressions that were introduced to the 3D rendered Thanos model.

Given an int variable n that has already been declared and initialized to a positive value , use a while loop to print a single line consisting of n asterisks. Use no variables other than n.
Final answer:
To print a line of n asterisks with a while loop using only the variable n, a loop would run to print an asterisk and decrement n by one until n reaches zero, without using additional variables.
Explanation:
To print a single line consisting of n asterisks using a while loop in a programming language without using any variables other than n, which has already been initialized to a positive value, you could use the following pseudocode:
while (n > 0) {
print("*");
n = n - 1;
}
This pseudocode highlights the use of a while loop to print asterisks. The loop continues to run as long as n is greater than zero, printing an asterisk and then decrementing n by one on each iteration. There is no need for additional variables; we are only manipulating the value of n within the loop.
In actual code, depending on the programming language you are using, you might use a function like print() or System.out.print() to print each asterisk without a newline character, allowing them to be printed on the same line.
