Create a macro named mReadInt that reads a 16- or 32-bit signed integer from standard input and returns the value in an argument
timofeeve [1]

Answer:

;Macro mReadInt definition, which take two parameters

;one is the variable to save the number and other is the length

;of the number to read (2 for 16 bit and 4 for 32 bit) .

You are to calculate the property tax for tax payers. You will ask the county tax clerk if they want to run the program and init
andre [41]

Answer:

Explanation:

The following code is written in Java. It creates the loop as requested and validates the information provided before continuing, if the information is invalid it prints "Invalid Information to the screen" and asks the user to enter the information again. Finally, outputing all the requested information at the end of the program. The code has been tested and the output can be seen in the attached image below.

import java.util.ArrayList;

import java.util.Arrays;

import java.util.Scanner;

class Brainly {

   public static void main(String[] args) {

       Scanner in = new Scanner(System.in);

       int totalValues = 0;

       int totalTaxes = 0;

       int count = 0;

       while(true) {

           int lotNumber, value;

           double tax;

           System.out.println("Would you like to add an Entry: 1=Yes 0=No");

           int answer = in.nextInt();

           if (answer == 1) {

               System.out.println("Please enter lot number: ");

               lotNumber = in.nextInt();

               if ((lotNumber >= 0) && (lotNumber <= 999999)) {

                   System.out.println("Please enter assessed value: ");

                   value = in.nextInt();

                   tax = value * 0.05;

                   System.out.println("Lot Number: " + lotNumber);

                   System.out.println("Property Value: " + value);

                   System.out.println("Property Tax: " + tax);

                   totalTaxes += tax;

                   totalValues += value;

                   count += 1;

               } else {

                   System.out.println("Invalid Lot Number");

               }

           } else {

               break;

           }

       }

       int average = totalTaxes / count;

       System.out.println("Total Property Values: " + totalValues);

       System.out.println("Total Property Taxes: " + totalTaxes);

       System.out.println("Average Property Tax" + average);

   }

When a program terminates because a thrown exception is not handled, the program:
castortr0y [4]

Answer:

Option (e)

Explanation:

Option (e) is the answer. It indicates the exception thrown and displays it. It also indicates the place where the exception was thrown ( at what line of the code the exception was thrown )

Option (a) is false as the program which was terminated because of an exception which was not handled doesn't starts automatically.

Option (b) is false as it doesn't opens a dialogue box about running the program another time or anything. It just terminates because of the unhandled exception.

Option (c) is false as it doesn't saves all the output to a disk file called the "runStackTrace.txt".

Option (d) is false as it doesn't open a dialogue box. The program terminates because of the unhandled exception.
