Construct an application named BookArray in which you create an array that holds 10 Book objects (5 Fiction objects and 5 NonFiction objects). Using a for loop, display the details about the 10 book objects.

Can you write it in Java, add comments    Create an application containing an array that stores eight integers. Prompt the user to enter the 8 integers. The application should call five methods that in turn (1) display all the integers, (2) display all the integers in reverse order, (3) display the sum of the integers, (4) display all values less than the calculated average value, and (5) display all values that are higher than the calculated average value.

A(n) ___ is used in an array to across each element?   a. Index   b. Subscript   C. Both a and b   d. None of the above

Using C# in Microsoft Visual Studio create an application that grades the written portion of the driver’s license exam. The exam has 20 multiple-choice questions. (The correct answers are provided in the screenshot.) the program should store these correct answers in an array. The program should read the student’s answers for each of the 20 questions from a text file and store the answers in another array. (Create your own text file to test the application.) After the student’s answers have been read from the file, the program should display a message indicating whether the student passed or failed the exam. (A student must correctly answer 15 of the 20 questions to pass the exam.) It should then display the total number of correctly answered questions, the total number of incorrectly answered questions, and a list showing the question numbers of the incorrectly answered questions.

Suppose a teacher has five students who have taken four tests. The teacher uses the following grading scales to assign a letter grade to a student, based on the average of his or her four test scores. Test Score Letter Grade 90-100 80-89 70-79 60-69 0-59 A B C D F Create an application that uses an array of strings to hold the five student names, an array of five strings to hold each student's letter grades, and five arrays of four single precision numbers to hold each student's set of test scores.

Which of the following will repeat the loop instructions for each row in atwo-dimensional array named intNum?a. For intRow As Integer = 0 To intNum.GetUpperBound(0)b. For intRow As Integer = 0 To intNum.GetUpperBound(1)c. intRow = 0Do While intRow < intNum.GetUpperBound(0)d. both b and c

The intNums array is declared as follows: Dim intNums() As Integer = {10, 5, 7, 2}. Which of the following blocks of code correctly calculates the average value stored in the array? The intTotal, intSub, and dblAvg variables contain the number 0 before the loop is processed. a. Do While intSub < 4 intNums(intSub) = intTotal + intTotal intSub += 1 Loop dblAvg = intTotal / intSub b. Do While intSub < 4 intTotal += intNums(intSub) intSub = intSub + 1 Loop dblAvg = intTotal / intSub c. Do While intSub < 4 intTotal += intNums(intSub) intSub += 1 Loop dblAvg = intTotal / intSub – 1 d. Do While intSub < 4 intTotal = intTotal + intNums(intSub) intSub = intSub + 1 Loop dblAvg = intTotal / (intSub – 1)
