Discuss what they need to consider if they wish to use their devices when they are away from home?
ANTONII [103]

Below are suggestions Ryan and Michael should be aware or when travelling away from home with portable personal digital devices.


Portability: This includes the size and weight. Always keep portable equipment like phones and laptops in your possession every time.

Power adapters or chargers: At one point, you will need to recharge your phone or laptop. Bring your charger, plug adapter or a voltage converter if traveling overseas.

Mobile networks or Data roaming charges: When traveling overseas, it is worth noting that your data plan will probably be very expensive. Be sure to turn off 3G and push services and disable notifications.

Connectivity and availability of the internet: Doing a research on the connectivity well before your departure date is vital. Ensure to find out whether free wireless is offered at your hotel. If you must connect to any public hot-spots, be careful not to enter personal information like passwords and credit cards numbers.

Personal security and the security of the device: If you are set to travel to a dangerous part of the world, leave your expensive electronics behind and find alternative ways of how you can stay in touch with family and friends

For this project you will write a Java program that will run a simple math quiz. Your program will generate two random integers
ElenaW [278]

Answer:

Here is the JAVA program:

import java.util.Scanner;   //to accept input from user

public class FunWithBranching {   //class name

   public static void main(String[] args) {  //start of main function

   Scanner input = new Scanner(System.in);  //creates Scanner object

   System.out.print("Enter your name: "); //prompts user to enter name

   String userName = input.nextLine();  //stores the name

   System.out.print("Welcome " + userName + "! Please answer the following questions:\n");   //prompts user to answer the questions

   int randomOperand1 =  (int)(20 * Math.random()) + 1;  //generates random number for operand 1 (1-20)

   int randomOperand2 =  (int)(20 * Math.random()) + 1;  //generates random number for operand 2 (1-20)

   int randomAdd = randomOperand1 + randomOperand2;  //performs addition of two random numbers and stores result in randomAdd

   int randomMul = randomOperand1 * randomOperand2;  //performs multiplication of two random numbers

   int randomDiv = randomOperand1 / randomOperand2;  //performs division of two random numbers

   int randomMod = randomOperand1 % randomOperand2;  //performs modulo of two random numbers

   int correctAns = 0;  //stores number of correct answers

   System.out.print(randomOperand1 + " + " + randomOperand2 + " = ");  //displays random number + random number

   int AdditionGuess = input.nextInt();   //reads the answer of addition from user and stores it in AdditionGuess

   if (AdditionGuess == randomOperand1 + randomOperand2) {  //if the user answer is correct

   System.out.println("Correct!");  //displays correct

   correctAns++;  //adds 1 to the count of correctAns every time the user gives correct answer of addition

 } else {  //if user answer is incorrect

   System.out.println("Wrong!");  //displays wrong

   System.out.println("The correct answer is " + randomAdd);   }  //displays the correct answer of addition

   System.out.print(randomOperand1 + " * " + randomOperand2 + " = ");  //displays random number * random number  

   int MultiplicationGuess = input.nextInt();   //reads the answer of multiplication from user and stores it in MultiplicationGuess

 if (MultiplicationGuess == randomOperand1 * randomOperand2) {  //if the user answer is correct

     System.out.println("Correct!");  //displays correct

     correctAns++;  //adds 1 to the count of correctAns every time the user gives correct answer of multiplication

 }else{  //if user answer is incorrect

       System.out.println("Wrong!");  //displays wrong

       System.out.println("The correct answer is " + randomMul);   }  //displays the correct answer of multiplication

   System.out.print(randomOperand1 + " / " + randomOperand2 + " = ");  //displays random number / random number  

   int DivisionGuess = input.nextInt();   //reads the answer of division from user and stores it in DivisionGuess

   if (DivisionGuess == randomOperand1 / randomOperand2) {  //if the user answer is correct

       System.out.println("Correct!");  //displays correct

       correctAns++;   //adds 1 to the count of correctAns every time the user gives correct answer of division

       }else{  //if user answer is incorrect

           System.out.println("Wrong!");  //displays wrong

           System.out.println("The correct answer is " + randomDiv);     }  //displays the correct answer of division

      System.out.print(randomOperand1 + " % " + randomOperand2 + " = ");  //displays random number % random number  

       int ModGuess = input.nextInt();  //reads the answer of modulo from user and stores it in ModGuess

           if (ModGuess == randomOperand1 % randomOperand2) {  //if the user answer is correct

           System.out.println("Correct!");  //displays correct

           correctAns++;   //adds 1 to the count of correctAns every time the user gives correct answer of modulo

           }else{  //if user answer is incorrect

               System.out.println("Wrong!");  //displays wrong

               System.out.println("The correct answer is " + randomMod);    }  //displays the correct answer of modulo

double percentage = correctAns * 25;   //computes percentage

System.out.println("You got " + correctAns + " correct answers.");   //display number of correct answers given by user

System.out.println("That's " + percentage + "%!");         }  } //displays percentage

Explanation:

The program is well explained in the comments mentioned with each line of code. The screenshot of the output is attached.
