Answer:

CMYK

Explanation:

Monitors typically use RGB color (additive model — adding to make white), but offset printing uses CMYK pigments (subtractive color — subtracting from the existing white). Printed images have less visual range, saturation, and contrast than digital images, so in print, colors will usually appear darker and less vibrant.

Discuss different ways to respond to errors, such as notifying the user onscreen, writing to an error log, notifying the develop

Ronch [10]

Answer:

Notifying the errors is always useful .

Explanation:

The errors should always be notified to the developer. It is useful and is important. When we provide notifications on the screen, it helps the user and it can be used to provide feedback. In regard to developmental work, it has to be important and confidential and we use the help of email to inform or notify errors to the organization. This will help the company from negative criticism and helps the company perform better. We can also write an error log when we face the same error again and again even after notifying the developer organization. This helps to put a reminder to the organization that immediate check has to be dome and eliminate the error from the source.

Some disadvantages are if we do not keep timer implementation, the alert keeps on popping on the screen, which is irritable.

ycow [4]

Answer:

I have added the code again with the mistakes are corrected please see the comments in code. You have mistake in while loop condition.

#include <iostream>

#include <iomanip>

#include <cmath>

using namespace std;

int options ();

int option1 ();

int option2 ();

int option3 ();

double addition (double num1, double num2);

double multiplication (double num1, double num2);

int main()

{

jump:

int option = 0;

cout << "1. Add" << endl;

cout << "2. Multiply" << endl;

cout << "3. Exit" << endl;

cout << "Enter option 1 for addition, option 2 for multiplication, or option 3 to exit" "Enter an option: ";

cin >> option;

switch (option)

{

case 1:option1;

int option1 ();

{

double num1 = 0;

double num2 = 0;

// void int key = 0;

cout << " Enter a number: ";

cin >> num1;

cout<< " Enter a second number: ";

cin >> num2;

double sum = addition(num1, num2);

cout << " Sum is: " << sum <<endl;

} break;

case 2: option2;

int option2 ();

{

double num1 = 0;

double num2 = 0;

cout << " Enter a number:";

cin >> num1;

cout << " Enter a second number: ";

cin >> num2;

double product = multiplication(num1, num2);

cout << " Product is: " << product << endl;

//system("cls");

}

break;

case 3: option3;

int option3();

{

return 0;

}

break;

default: cout << " Invalid number entered: ";

}

//do {main();}

//while (option < 3); //you have mistake in this loop please have a look

while (option<3)

{

goto jump;

}

double addition(double num1, double num2)

{

return num1 + num2;

}

double multiplication(double num1, double num2)

{

return num1*num2;

}

Explanation:

You can also do this by using goto statement in switch case and menu will be repeated until the user not select to exit and now it will work with the loop as well.

I hope it will help you!

meriva

ANSWER

The program in JAVA for the given scenario is as follows.

import java.util.*;

public class Car

{

// variables declaration

static int _year_model;

static String _make;

static int _speed;

public static void _init_( int model, String m )

{

// variables initialization

_year_model = model;

_make = m;

_speed = 0;

}

public static void accelerate()

{

_speed = _speed + 5;

}

public static void brake()

{

_speed = _speed - 5;

}

public static int get_speed()

{

// current value of speed is returned

return _speed;

}

public static void main(String[] args) {

// object of class created

Car ob = new Car();

// method called using object of class

ob._init_(2019, "audi");

ob.accelerate();

System.out.println("Accelerated speed " + ob.get_speed());

ob.accelerate();

System.out.println("Accelerated speed " + ob.get_speed());

ob.accelerate();

System.out.println("Accelerated speed " + ob.get_speed());

ob.accelerate();

System.out.println("Accelerated speed " + ob.get_speed());

ob.accelerate();

System.out.println("Accelerated speed " + ob.get_speed());

System.out.println();

ob.brake();
