Which of the following statements is true?

The length of a hailstone sequence is the number of terms it contains. For example, the hailstone sequence in example 1 (5, 16,

11111nata11111 [884]

Answer:

Following are the program to this question:

#include <iostream> //defining header file

using namespace std;

int hailstoneLength(int n) //defining method hailstoneLength

{

int t=1; //defining integer variable assign

while(n!=1) //define a loop that checks value is not equal to 1

{

if(n%2==0) // check even number condition

{

n=n/2; // divide the value by 2 and store its remainder value in n

t++; //increment value of t by 1.

}

else

{

n=n*3+1; //calculate and hold value in n

t++; //increment value of t variable by 1

}

return t; //return value

}

int main() //defining main method

{

int n; //defining integer variable

cout<<"Enter any number: "; //print message

cin>> n; //input value

cout<<hailstoneLength(n); //call method and print its value

return 0;

}

Output:

Enter any number: 3

8

Explanation:

Program description can be given as follows:

In the given C++ language program an integer method "hailstoneLength", is declared, that accepts an integer variable "n" in its parameter.
Inside the method, an integer variable t is declared, that assign a value that is 1, in the next line, a while loop is declared, that uses if block to check even condition if number is even it divide by 2 and increment t variable value by 1.
If the number is odd it will multiply the value by 3 and add 1 and increment t by 1 then it will go to if block to check value again. when value of n is not equal to 1 it will return t variable value.
In the main method, an integer variable "n" is used that call the method and print its return value.

A regular polygon is an n-sided polygon in which all sides are of the same length and all angles have the same degree (i.e.,the

butalik [34]

import java.util.Scanner;

public class polygon {

/** Main Method */

public static void main(String[] args) {

Scanner input = new Scanner(System.in); // Create a Scanner

// Prompt the user to enter the number of sides

// and the side of a regular polygon

double side = input.nextDouble();

// Display the area of the regular polygon

}

/** Method area computes and returns the area of a regular polygon */

public static double area(int n, double side) {

return (n * Math.pow(side, 2) / (4 * Math.tan(Math.PI / n)));

You have compiled a new kernel using rpm. when you reboot, the new kernel is not the default selection on the boot menu. you use

vredina [299]

First, rpm is RedHat Package Manager. Compilation is done with gcc, the GNU C Compiler.

To add that kernel to grub2's menu, as root you'd need to run:

grub2-mkconfig > /boot/grub2/grub.cfg #redirection is favored by Red Hat

Check out the man page @ man grub2-mkconfig

Write a CashRegister class that can be used with the RetailItem class that you wrote in Chapter 6's Programming Challenge 4. The

lys-0071 [83]

Answer:

Following are the code to this question:

import java.util.*; //import package for user input

class RetailItem//defining class RetailItem

{

private String desc;//defining String variable

private int unit;//defining integer variable

private double prices;//defining double variable

RetailItem()//defining default Constructor

{

//Constructor body

}

Output:

The Sub Total value: 199.75

The Sales Tax value: 11.985

The Total value: $211.735

Explanation:

In the above code three class "RetailItem, CashRegister, and Main" is defined, in the class "RetailItem", it defines three variable that is "desc, unit, and prices", inside the class "get and set" method and the constructor is defined, that calculates its value.

In the next step, class "CashRegister" is defined, and inside the class parameterized constructor is defined, which uses the get and set method to return its value.

In the next step, the main class is declared, in the main method two-class object is created and calls its method that are "getSubtotal, getTax, and getTotal".

There is some technical error that's why full code can't be added so, please find the attached file of code.
