- Which of the following are true about arrays? Arrays are reference types. Array indexing is bounds‐checked. Arrays sometimes can be created without using new. The entire contents of an array can be copied via =.8. Which of the following statement is correct? If we pass the reference using out, value should be initialized in the called method If we pass the reference using ref, value should be initialized in the called method Using ref we also can call a method by passing value O If we pass the reference using out, value should be initialized in the called method 9. While using params, the parameter can be a single variable, one dimensional array as well as a two-dimensional array. True FalseWhat transpires when a parameter for an array is sent in with either the ref or out keyword, and the results are observed?
- Write the code of dynamic array with the name of ‘A’ and you will get the size of array from user and also get the values of array from the user and display that values on screen. TRY TO ADD COMMENTS IN THE CODE TOOC++ Programing NOTE: The important method has been ATTRIBUTES given to you. userld:int //generates unique id from 10001 upwards username:string firstname:string lastname:string dob:string INSTRUCTION 1 The program should generate unique userld whenever new object is created. Notice that idGenerator is static variable, so assign the current value of idGenerator to userld, so that each user will have unique user id (Starting from 10001). age: int idGenerator: static int; totalUsers : static int www МЕТНODS Then increment idGenerator by 1. INSTRUCTION 2 User() User(string, string, string, int) User(const User&) "User() The totalUsers is also a static variable. This should keep track of the total users in the class. With the Above UML for CLASS USER, answer the following questionsIn this assignment, you will decide how to keep the inventory in the text file. Then your program must read the inventory from the file into the array. Each product must have a record in the file with the name, regular price, and type. There are several options for storing records in the file. For example, • each value takes one line in the file (i.e., three lines for one product). Then you must take care of correct handling of the ends of the lines; • all values are in one line that can be read as a string. Then you must handle the parsing of the string; • all values are in one line separated by a delimiter. Then you must handle a line with delimiters. Assume that the inventory does not have more than 100 products. But the actual number is known only after the reading of the file. Once you can read data from the file into the array, you must add a new property to the product class – a static variable that holds the number of products in the inventory. Its value must grow as reading…
- 3 a)What are the contents of the array at the end of the running program BasicArray in the previous step? b)What two lines in the BasicArray class above where the array elements are being retrieved (get). c)What two lines in the BasicArray class above where the array elements are being set to a value? In one of those two places where the array elements are set, the array element is being initialized (setfor the first time), which one is that?

You should also have the following function in this new client program: a) Enter details for each baby (name and age) and thus populate the Baby ArrayList b) Calculate and display the average age of all babies in the ArrayList c) Ask the user to enter the name of a baby, and then remove it from the ArrayList d) Allow the user to add new baby information in the ArrayList e) Output the details of each baby from the ArrayList (name and age) Compare this client program using the ArrayList with the client program you have done using array, comment on the differences between the two. Modify your client program in the last question, by adding a sort function such that when that option is selected, it sorts the ArrayList using the baby names in alphabetical order and output the details in the sorted ArrayList to a CSV (sortedbabylist.csv) file. public class Baby { private String name; private int age;…Thank you in advance sir/ma'am!!Questions: 1) What is the attribute of an array that is used to determine the maximum number of items (number of cells) that may be placed in an array? 2) What term is used to refer to one data item in an array? 3) Which is used to assign data items to an array when the array is declared? 4) This is the process of actually creating the array object and associating it with the array variable. Give a one-word answer.Array Processing. In this problem, you have two tasks: To create the header file, arrayOptn.h, and add the function declarations of the following functions listed below. To create the file, arrayOptn.c, which implements the functions in the arrayOptn.h You are already provided with the main() function. Do not edit anything there in the main.c file. List of functions to be implemented: 1 - void createArray(int arr[], int count, int maxCapacity) Parameters: int arr[] - a reference to an array int count - the number of elements to be inputted by the user and to be stored in the array int maxCapacity - the max capacity of the array Description: Asks the user for the elements of the array. The prompt message is: "Enter element at index N: " where N is the current index position being scanned. Each inputted integer must be unique. If an element already exists in the array, you prompt the user the message "Inputted element already exists, try another number" If the count is…The purpose of this program is to write a series of function to manipulate a two-dimension array. ArrayData method: It will allocate a block of memory which represents a two-dimension array based on the input values supplied by the user. Ask the user to enter the number of rows and column for 2D array that the user want to manipulate. The number of rows and columns that the user enters may or may not define a square matrix (when the number of rows equals the number of columns). The array will have exactly rows time columns (m * n) elements. It will not contain any extra or empty cells. Initialize the “matrix” by rows with random number between 1 to 100. Pass two arguments by out reference so that you can assign the number of row and columns of data to the first and second arguments. This is return 2D array method after allocating new memory for 2D array and initialize it with random value. Generate random number code in C# as following: Random randnum = new Random( );…SEE MORE QUESTIONS
