Passing Array as Argument

An array is a data structure that holds only fixed-size data and its contents are arranged in contiguous memory slots. The primary purpose of using an array is to store data items of the identical type together. An array can stockpile any one of the following types of data: int, float, char and so forth. The elements are stored from index 0, and the difference between the two indexes of the array is termed as an offset. The array has a fixed size. Once the size is defined during array declaration, it cannot be changed later.

Create a class called Array for performing a float one dimensional array. Define all the necessary variables to represent the private part. Provide a constructor that enables an object of this class to be initialized when it's declared. The constructor should contain default size in case no initializers are provided which is 10. Provide a proper destructor. Provide public methods that perform each of the following tasks: Set the array values (Set). This function sets the array elements with a specific location. Get the array values (Get). This function returns the array element with a specific location. Function called Max to get the maximum element of the array. Write a program to test your class. Define an object (array) with size 20 and another object with the default value. Fill the two arrays with values. Find the maximum number of the first array.

5. Complete the class code below and include a method named partition which takes an integer array and a partition integer as parameters and then partitions the original array into two new arrays where elements of the first array are all less than or equal to the partition integer and the second array are all greater than the partition integer. The method should print the original array, followed by the lower partition and finally the upper partition. Nothing should be returned by the method. For example, given int[ ] arr = {1, 45, 16, 7, 39, 6, 5, 11, 72, 31, 15} a method call to partition(arr, 11) should output: %3D [1, 45, 16, 7, 39, 6, 5, 11, 72, 31, 15] [1, 5, 6, 7, 11] [15, 16, 31, 39, 45, 72] public class Partition { public static void main(String[] args) { int[] arrayToPartition = {1, 45, 16, 7, 39, 6, 5, 11, 72, 31, 15}; %3D int partitionNumber = 11; partition(arrayToPartition, partitionNumber); } /l your method code here } // end of Partition class

1- Write a class called items that has member variables name (string), price (double), quantity (integer). In main program, create an array of type items called arrayltem and store several item objects in this array. Note that main should create several item objects and save these objects in arrayltem. Write a static method called totalCost that accepts an array of items. This static method must calculate and return the total cost of items stored in the array. 2- Write a generic method called minimum that accepts four items and find the minimum of them. 3- Test your class with Integer, Double, Character, String and Car objects.
Problem 1: Complete the sumOfDiagonals method in SumOfDiagonals.java to do the following: The method takes a 2D String array x as a parameter and returns no value. The method should calculate and print the sum of the elements on the major diagonal of the array x. In order to have a major diagonal, the array passed into the method should be a square (n-by-n), if it's not a square your program should handle that situation by throwing an exception. (Do Not worry about ragged arrays) If the array is a square, but there is a non-integer value on the major diagonal, your program should handle that situation by throwing an exception. When handling the exceptions, be as specific as you can be, (i.e. Do Not just use the Exception class to handle all exceptions in one catch block). Make the proper calls to the sumOfDiagonals method from the main method to test your sumOfDiagonals method on all the String arrays provided in the main method.
1) Write a method that returns the range of an array of integers. The range is the difference between the highest and lowest values in the array. The signature of the method should be as follows. public static int computeRange(int[] values)

Moving Between Rooms - Navigation In this assignment, you will be working with a given "rooms" dictionary and associated constants to create a simple text-based game. Your main task is to develop a function that allows the player to navigate through the rooms based on the given specifications. You need to implement the function found in the starter code to the right The function should take into account the following conditions: If the direction leads to an exit, set the next room to the exit and the message to "Goodbye". If the direction is invalid, set the next room to the current room and the message to "No such direction". If the direction is valid, but you cannot go that way, set the next room to the current room and the message to "You bumped into a wall". If the direction is valid and you can go that way, set the next room to the room in that direction and the message to "Empty". To help you understand how the function will be integrated into the gameplay loop, the following…
Please use easy logic with proper indentations and comments for understanding!. Coding should be in C++. 3. Define a class which stores up to 10 integer values in an array. The class should also define the following 4 public methods: setNumber – accepts an integer value to store in the array. The value is stored in the next available element of the array (first call to the method stores the value in element 0 with the second call storing the value in element 1.) The method returns true if there is room in the array and the integer was successfully stored. Returns false otherwise. clear – removes all values from the array so that the array can be reused. displayNumbers – displays the values currently stored in the array. getStats – determines the largest, smallest, and average of the values currently stored in the array. These values are returned to the caller via reference parameters. All methods should produce correct results regardless of the order in which…
Python Programming: Write a program using unittest.TestCase methods to confirm that the addition and subtraction of date and timedelta objects produce correct results. Important notes: Use the unittest module to create a TestCase to test that the addition and subtraction of date and timedelta objects produce correct results... For example I could create a TestCase with a function that tests the addition of date and timedelta objects; a function that tests the subtraction of date and timedelta and then call unittest's main method at the end. When you run this program, it should tell us whether the text was successful or not. See attached image for what the output should look like.
