Is memory allocated when an array is declared? Do the elements in the array have default values? What happens when the following code is executed? int numbers[30];cout << "numbers[0] is " << numbers[0] << end1;cout << "numbers[29] is " << numbers[29] << end1;cout << "numbers[30] is " << numbers[30] << end1;

If the following array declarations are valid, write "VALID". Otherwise, make assumptions and write a correct declaration. int[50] list; 1. int size; double[] list=new double[size]; 2. int[] test=new int[-5]; 3. double[] sales=new double[25.5]; 4. int x,y; char[x][y] board=new board[][] 5.
23. What are the values of the elements in the array numbers after the following code is executed? int[] numbers = {10, 20, 30, 40, 50, 60, 70, 80, 90, 100}; for (int i =1, i < 10; 1++) { numbers[i] = numbers [i - 1]; }
1)Examine the above code that creates the array: a)How is the base type of the array specified? b)How is the length of the array specified? c)How many Strings are actually stored in the array after the array has been created? d)How is the base type of the ArrayList specified? e)How is the capacity of the ArrayList specified? f)What is the capacity of the ArrayList? g)What is the size of the ArrayList?
Determine whether the following array declarations are valid. If a declaration is valid, write VALID. If it is invalid, you can make assumptions and write a correct declaration. a) int x, y; char[x][y] board = new board[][]; b) int size; double[] list = new double[size]; c) int[] test = new int[-5]; d) double[] sales = new double[25.5]; e) int[50] list;
The bank will store a record for each account consisting of a customer number (an integer) representing the owner of the account, an account type (a single char: C for chequing, S for savings, and M for mutual fund), and the balance of the account (a double). These are kept in three arrays-an array of customer numbers, an array of types, and an array of balances. A sample of what this might look like appears below: Customer Array 102241 992944 992944 Type Array C S C Balance Array 1.29 22.50 1.24 The entries in the array correspond to one another-for example, the first slot in all three arrays represent the fact that customer number 102241 has a chequing account with $1.29 in it. As is shown, the same customer number can appear several times, as customers can have more than one account. These are called parallel arrays, because the slots in each correspond, and the really important thing about parallel arrays is that if you shuffle around anything in one array, you have to…

Question1: implement lab 3 by the two-dimensional array. ask the user to give you a number of rows and the number of columns. and then you define a two-dimensional array. then your program will print the multiplication table according to the numbers that the user gave. C++
Correct the following code so that it correctly initializes and outputs the elements of the array intList. int intList [5];for (int i = 0; i > 5; i--)cin >> intList [i];for (int i = 0; i < 5; i--)cout << intList << " ";cout << endl;

A three-dimensional array called watermelon is declared as based on the row-wise manner as below: int watermelon [3][2][2]= {9, 7, 1, 5, 9, 7, 1, 5, 9, 7 ,1, 5}; Rewrite the sequence of watermelon array if it is accessed in column wise manner. Select one: A.9 9 9 7 7 7 1 1 1 5 5 5 B.9 7 1 5 9 9 7 7 1 1 5 5 C.5 1 7 9 5 1 7 9 5 1 7 9 D.9 7 1 5 9 7 1 5 9 7 1 5
. Now take any name from the user, find whether that name is present in that array or not, and print the position of that name in the array if found. Write a search method to sequentially search the name from the array. Invoke the search method from the main method. The array and the name to be searched should be passed into the search method as parameters.Now write a Java program to implement binary search for the above problem.[Hint: You can use equals() and compareTo() methods of String class.]
