A(n) _________ may be used to pass arguments to the constructors of elements in anobject array.

Lab 5 : Arrays Please the attachment which is been given to Develop a C code that asks for a class size (maximum can be 20). Then it asks the user to enter all the marks and saves them in an array. Then it generates a report about the class status that includes the following 1- Class average 2- Best mark and worst mark 3- number of failed students 4- Number of students with a grade of A and higher (80 or above) 5- number of students who got a mark above average

JAVA PROGRAM Chapter 7. PC #16. 2D Array Operations Write a program that creates a two-dimensional array initialized with test data. Use any primitive data type that you wish. The program should have the following methods: • getTotal. This method should accept a two-dimensional array as its argument and return the total of all the values in the array. • getAverage. This method should accept a two-dimensional array as its argument and return the average of all the values in the array. • getRowTotal. This method should accept a two-dimensional array as its first argument and an integer as its second argument. The second argument should be the subscript of a row in the array. The method should return the total of the values in the specified row. • getColumnTotal. This method should accept a two-dimensional array as its first argument and an integer as its second argument. The second argument should be the subscript of a column in the array. The method should return the…

When an array is passed as a parameter to a method, modifying the elements of the array from inside the function will result in a change to those array elements as seen after the method call is complete. O True O False

17. Phone Book ArrayList Write a class named PhoneBookEntry that has fields for a person's name and phone number. The class should have a constructor and appropriate accessor and mutator methods. Then write a program that creates at least five PhoneBookEntry objects and stores them in an ArrayList. Use a loop to display the contents of each object in the ArrayList.

struct remove_from_front_of_vector { // Function takes no parameters, removes the book at the front of a vector, // and returns nothing. void operator()(const Book& unused) { (/// TO-DO (12) ||||| // // // Write the lines of code to remove the book at the front of "my_vector". // // Remember, attempting to remove an element from an empty data structure is // a logic error. Include code to avoid that. //// END-TO-DO (12) /||, } std::vector& my_vector; };

C++ CODE HELP NEEDED NEED  MISSING CODE THAT WILL  Read an integer as the number of Goat objects. Assign myGoats with an array of that many Goat objects. For each object, call object's Read() followed by the object's Print(). Ex: If the input is 2 5 87 7 71, then the output is: Goat's age: 5 Goat's weight: 87 Goat's age: 7 Goat's weight: 71 Goat with age 7 and weight 71 is deallocated. Goat with age 5 and weight 87 is deallocated.   #include <iostream>using namespace std; class Goat {   public:      Goat();      void Read();      void Print();      ~Goat();   private:      int age;      int weight;};Goat::Goat() {   age = 0;   weight = 0;}void Goat::Read() {   cin >> age;   cin >> weight;}void Goat::Print() {   cout << "Goat's age: " << age << endl;   cout << "Goat's weight: " << weight << endl;}Goat::~Goat() { // Covered in section on Destructors.   cout << "Goat with age " << age << " and weight " <<…

In C++ struct myGrades { string class; char grade; };   Declare  myGrades as an array that can hold 5 sets of data and then set a class string in each position as follows: “Math” “Computers” “Science” “English” “History” and give each class a letter grade

Lab9C: 2D or not 2D For this exercise you will also be writing a program that will be building upon Lab9A. So please make new class file, copy, and rename the code you have already written for Lab9A. Please also rememb to rename the file and (and in the case of Java and C# students) class name to Lab9C. For this exercise, please take the array that was filled up with values and flatten it i.e., convert the 2-0 array to a 1-D array that contains the same values. Please do not just print the 2-D array to look li a 1-D array Hint: You will have to take the 2-D array's total amount of cells and make a 1-D array of the same siz Please refer to the sample output below for visualization and match its style. As always: Remember, the class name should be Lab9C. The user input is indicated in bold. Sample Output #1: Please enter the number of rows: 4 Please enter the number of columns: 4 I have 4 rows and 4 columns. I need to fill-up 16 spaces. The 4x4 array: 1|2|3|4| 5|6|7|8| 9|10|11|12|…

10. Lottery Application Write a Lottery class that simulates a lottery. The class should have an array of five integers named lotteryNumbers. The constructor should use the Random class (from the Java API) to generate a random number in the range of 0 through 9 for each element in the array. The class should also have a method that accepts an array of five integers that represent a per- son's lottery picks. The method is to compare the corresponding elements in the two arrays and return the number of digits that match. For example, the following shows the lotteryNumbers array and the user's array with sample numbers stored in each. There are two matching digits (elements 2 and 4). lotteryNumbers array: User's array: 7 4 4 2 1 3 7 3 In addition, the class should have a method that returns a copy of the lotteryNumbers array. Demonstrate the class in a program that asks the user to enter five numbers. The program should display the number of digits that match the randomly generated…
