Array

The simplest way to start thinking about an array is as a collection, or a set of elements. In programming, these elements may be constants, variables, functions and pointers.

<?php $marks = array(

"Sara" => array(

"Programming" => 95,

"DataBase" => 85,

"Web" => 74,

"Diana" => array(

"Programming" => 78,

"DataBase" => 98,

"Web" => 66,

"Amy" => array(

"Programming" => 88,

"Web" => 99,

);

1 : sort the array by the name of student from A-Z;

2 : search if Ram is exist :

if exiset print the value; else : student does not exist

3 : calculate the avg of each student and print it as :

the avg for Sara is : 84.66

True or False When you create a numeric array in C#, its elements are set to the value 0 by default.
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…

Module/Week 8 ASSIGNMENTImagine you are using a two-dimensional array as the basis for creating the game battle- ship. In the game of battleship a `~' character entry in the array represents ocean (i.e., not a ship), a `#' character represents a place in the ocean where part of a ship is present, and a `H' character represents a place in the ocean where part of a ship is present and has been hit by a torpedo. Thus, a ship with all `H' characters means the ship has been sunk. Declare a two-dimensional array that is 25 x 25 that represents the entire ocean and an If statement that prints "HIT" if a torpedo hits a ship given the coordinates X and Y. Create a text file of 25 line. Each line has 25 characters. ~ represents water and # represents part of a ship. This file is the battleship game board. An example file might look like: Then write a C++ program that will read in the file representing the game board with 25 lines where each line has 25 characters corresponding to the description…
