CLS N = 1 FOR J = 1 TO 5 PRINT N N = 10*N+1 NEXT J END

Lemur [1.5K]

Answer:

1

11

111

1111

11111

Explanation:

Given

The above QBasic code

Required

The output

The iteration on the third line is repeated 5 times; i.e. for values of j from 1 to 5.

In each iteration, the value of N is printed and the next value is calculated.

Initially, the value of N is 1 ---- on line 2

So, 1 is printed first. The next value of N is as follows:

$N = 10 * N + 1$ --- we keep replacing N (on the right-hand side) with current N value.

So, we have:

$N = 10 * 1 + 1 =11$

$N = 10 * 11 + 1 = 111$

$N =10 *111+1 = 1111$

$N =10 *1111+1 = 11111$

Which threading model is best for achieving true parallelism and how?

WITCHER [35]

Answer:

The explantion of this question is given below in the explanation section.

Explanation:

Parallelism means that an application is split into smaller subtasks that can be processed in parallel on multiple CPU at the same time. Parallelism is related to application handling individual tasks on multiple CPUs. To achieve true parallelism your application must have more than one thread running, schedule the task into other threads, graphics cards, and CPU, etc.

It is noted that parallelism is a concept while multiple threading in computer programing is its implementation. Some operating systems provide a multiple threading that combined the user-level thread and kernel-level thread facility. In such a system, multiple threads within the same application can run in parallel on multiple CPU or processors

There are three types of Multithreading Model

• Many to many relationships.

• Many to one relationship.

• One to one relationship.

Many to many relationship

This model multiplexes any number of user threads onto an equal or smaller number of kernel threads. However, this model provides the best accuracy to concurrency. However, using this model, true parallelism can be achieved, if the system has multiprocessor.

Many to One model

This model maps the user-level threads to one kernel-level thread and its management is done in userspace by the thread library. In this model, only one thread can access the Kernal at a time, so multiple threads are unable to run on multiple CPU in parallel.

One to one relationship

This model provides one to one relationship between the user and kernel-level thread. This model is better than the many-to-one model. It allows another thread to execute when a thread makes a blocking system call. However, it supports multiple threads to execute in parallel on the microprocessor. This model provides true parallelism.

Create a function (prob3_6) that will do the following: Input a positive scalar integer x. If x is odd, multiply it by 3 and add

aniked [119]

Answer:

Following are the program in python language

def prob3_6(k): #function definition

c = 0 #variable declaration

while k != 1: #iterating the while loop

print(k) #print k

if k % 2 == 0:#check if condition

k= k // 2 #divisible by 2

else: #else condition

k = k * 3 + 1

c = c + 1

print(k) #print k

print c #print count

prob3_6(3)#function call

Output:

3

10

5

16

8

4

2

1

7

Explanation:

Following are the description of program

Create a function "prob3_6" in this function we passing an integer parameter of type "int" named "k".

Inside that function we declared a variable "c" of type "int" that is used for counting purpose .
After that we iterated the while for print the value of when it is not equal to 1 .
We check if condition when k gives 0 on modulus then k is divisible by 2 otherwise else block will be executed in the else part we multiply by 3 to k and add 1 to the k variable .
Finally print "k" and "c"

What is the output of this code? import java.util.HashSet; class A { public static void main(String[ ] args) { HashSet set = new

kompoz [17]

Answer:

The code will give an error that is "At least one public class is required in main file".

Explanation:

In the given code if we do not use the public access modifier to the class. It will give an error so, the correct code to this question as follows:

Program:

import java.util.HashSet; //import package

public class A //define class as public.

{

public static void main(String[ ] args) //define main method.

{

HashSet set = new HashSet(); //creating hashset object.

set.add("A"); //add alphabet in hashset

set.add("B"); //add alphabet in hashset

set.add("C"); //add alphabet in hashset

System.out.print("Size of HashSet is :"set.size()); //print the size of hashset.

}

Output:

Size of HashSet is : 3

Explanation of the program:

In the above program, we define a public class that is "A" and inside the class, we define the main method.

Inside the main method, we create a HashSet class object that is "set".

To add elements in HashSet we use add() function that adds elements and in the last, we use the size() function that prints the size HashSet.

Which role involves designing and creating advertisements for marketing purposes?

SOVA2 [1]

Answer: I cant give you an exact answer, but your options are gonna be B or C.

Explanation: A computer programmer actually doesn't work with a marketing company at all, most of them work from home as it is. And a Tech Support Specialist may work with a marketing firm, but it would be strictly IT stuffs.
