A ________ is a term used to describe a select list that allows the user to select an option to load another web page.

He following is a string of ASCII characters whose bit patterns have been converted into hexadecimal for compactness: 4A EF 68 6

almond37 [142]

Answer:

a) Please see below as the answer is self explanatory.

b) odd parity.

Explanation:

As the hexadecimal system, has as its base the decimal 16, which is the 4th power of 2 (base of the binary system), each hexadecimal digit can be expressed of a linear combination of 4 binary digits, as follows:

Hex = b₃*2³ + b₂*2² + b₁*2¹ + b₀*2⁰, where bₙ = 0 or 1.

So, we can convert the hexadecimal bit pattern to binary, as follows:

4A = 01001010

Now, if the leftmost bit is a parity bit, the ASCII code is represented by the 7 rightmost bits:

⇒ ASCII = 1001010 = 74

Repeating the same process for the remaining pairs of hex digits, we have:

EF = 11101111 ⇒ ASCII = 1101111 = 111

68 = 01101000 ⇒ ASCII = 1101000 = 104

20 = 00100000 ⇒ ASCII = 0100000 = 32

C4 = 11000100 ⇒ ASCII = 1000100 = 68

EF = 11101111 ⇒ ASCII = 1101111 = 111

E5 = 11100101 ⇒ ASCII = 1100101 = 101

b) Due to any pair of digits has an odd number of 1s, the parity used is odd parity.

A series circuit contains a generator, two devices, and connecting wires. The resistances of the two devices are 15 ohms and 10

rjkz [21]

We know, Voltage drop = Voltage * Resistor / total resistance
Here, voltage = 75 V
Resistor for cal. = 10 Ohm
Total resistance = 10 + 15 = 25 Ohm

Substitute their values,
e = 75 * 10/25
e = 3 * 10
e = 30 V

In short, Your Answer would be Option B

Hope this helps!

Swapping Order of Vowels Write a program to swap the order of the vowels in a given word. For example, if the word is programmin

Georgia [21]

Answer:

Program is as follow:

Explanation:

#include<iostream.h>

#include < conio.h>

bool isVowel(char b)

{

return

( b=='a' || b=='A' || b=='e' || b=='E' || b=='i' || b=='I' || b=='o' || b=='O' || b== 'u' || b=='U');

For swaoing the vowels

string reverseVowel ( String str)

{

int j = 0;

string v ;

for ( int i= 0 ; str [i]]!='0'; i++)

if( isv(str[i]))

v[j++] = str[i[;

for ( int i = 0; str[i]! = '0' ; i++

if ( isv (str[i]))

str{i} = v [--j]

return str;

}

int main ()

{ string str = " Programming";

cout<<swapv(str);

return 0 ;

}

For this lab you will write a class to create a user-defined type called Shapes to represent different shapes, their perimeters

<h2>Answer:</h2>

<u />

========= Shape.java ===========

//import the Scanner class

import java.util.Scanner;

public class Shape{

//required fields

private String shape;

private double area;

private double perimeter;

//default constructor

public Shape(){

this.shape = "unknown";

this.area = 0.0;

this.perimeter = 0.0;

}

//constructor with one parameter

public Shape(String shape){

this.setShape(shape);

this.area = 0.0;

this.perimeter = 0.0;

}

//accessors and mutators

public void setShape(String shape){

this.shape = shape;

}

public String getShape(){

return this.shape;

}

public double getPerimeter(){

return this.perimeter;

}

public double getArea(){

return this.area;

}

public void setPerimeter(Scanner scr){

if(this.getShape().equals("circle")){

System.out.println("Enter the radius of the circle");

double radius = scr.nextDouble();

this.perimeter = 2 * 3.142 * radius;

}

else if(this.getShape().equals("rectangle")){

System.out.println("Enter the width");

double width = scr.nextDouble();

System.out.println("Enter the height");

double height = scr.nextDouble();

this.perimeter = 2 * (width + height);

}

else if(this.getShape().equals("square")){

System.out.println("Enter the height or width");

double height = scr.nextDouble();

this.perimeter = 4 * height;

}

else if(this.getShape().equals("unknown")){

System.out.println("You must define a shape first before calculating perimeter");

this.perimeter = 0.0;

}

else {

System.out.println("You must define a shape first before calculating perimeter");

this.perimeter = 0.0;

}

public void setArea(Scanner scr){

double radius = scr.nextDouble();

this.area = 3.142 * radius * radius;

}

else if(this.getShape().equals("rectangle")){

System.out.println("Enter the width");

double width = scr.nextDouble();

System.out.println("Enter the height");

double height = scr.nextDouble();

this.area = width * height;

this.area = 0.0;

}

else {

this.area = 0.0;

}

//Own methods

//1. Method to show the properties of a shape

public void showProperties(){

System.out.println();

System.out.println("The properties of the shape are");

System.out.println("Shape : " + this.getShape());

System.out.println("Perimeter : " + this.getPerimeter());

System.out.println("Area : " + this.getArea());

}

//2. Method to find and show the difference between the area and perimeter of a shape

public void getDifference(){

double diff = this.getArea() - this.getPerimeter();

System.out.println();

System.out.println("The difference is " + diff);

}

========= ShapeTest.java ===========

import java.util.Scanner;

public class ShapeTest {

public static void main(String [] args){

Scanner scanner = new Scanner(System.in);

// create an unknown shape

Shape shape_unknown = new Shape();

//get the shape

System.out.println("The shape is " + shape_unknown.getShape());

//set the area

shape_unknown.setArea(scanner);

//get the area

System.out.println("The area is " + shape_unknown.getArea());

//set the perimeter

shape_unknown.setPerimeter(scanner);

//get the perimeter

System.out.println("The perimeter is " + shape_unknown.getPerimeter());

// create another shape - circle

Shape shape_circle = new Shape("circle");

//set the area

shape_circle.setArea(scanner);

//get the area

System.out.println("The area is " + shape_circle.getArea());

//set the perimeter

shape_circle.setPerimeter(scanner);

//get the area

System.out.println("The perimeter is " + shape_circle.getArea());

//get the properties

shape_circle.showProperties();

//get the difference between area and perimeter

shape_circle.getDifference();

}

<h2>Sample output:</h2>

The shape is unknown

You must define a shape first before calculating area

The area is 0.0

You must define a shape first before calculating perimeter

The perimeter is 0.0

Enter the radius of the circle

>> 12

The area is 452.448

Enter the radius of the circle

>> 12

The perimeter is 452.448

The properties of the shape are

Shape : circle

Perimeter : 75.408

Area : 452.448

The difference is 377.03999999999996
