Look at the following array definition.
double sales [8] [10];
A) How many rows does the array have?
B) How many columns does the array have?
C) How many elements does the array have?
D) Write a statement that stores 3.52 in the last column of the last row in the array.
Questions 28- 30 are for students who have covered Chapter 7 on classes and structures. These questions use the following Car structure declaration.
struct Car
{
string make,
model;
int year;
double cost ;
// Constructors
Car()
{make= model=""; year= cost= O; }
Car(string mk, string md, int yr, double c)
{ make= mk; model = md; year= yr; cost = c; }
} ;

- 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…arrow_forwardC# application that will allow users to enter values store all the expenses on that month in an array clothes, food, cool drinks, water, meatarrow_forwardProject 5 - Magic Squares Objectives The objective of this project is to have students practice with two-dimensional arrays and loops. Specifications In this project, you will write code to determine if a two-dimensional array of ints is a Magic Square. For a two- dimensional array of ints to be a Magic Square all of the following must be true: 1. The array must be square - in other words, the lengths of all rows and all columns must be the same. 2. The array must contain all integers from 1 to n*n, where n is the length of the rows and columns. 3. The sum of the numbers in each diagonal, each row, and each column must be the same. You have been given two classes: • MagicSquareTest.java - Contains JUnit test cases for the MagicSquare class. Your code must pass all these tests. • MagicSquare.java - contains static methods to determine if a two-dimensional array of ints is a Magic Square: o isMagicSquare() - returns true if a two-dimensional array of ints meets all the criteria to be a…arrow_forward
- Question 2 You are about to create a simple 2D shooting game. i) Create appropriate structures with the following information: Bullet isAvailable: bool Gun type: The gun type (e.g. Rifles or Pistol) bulletSize: Total bullets in the gun (e.g. 6 bullets in Pistol) bullets: An array of Bullet type. Maximum 100 bullets applied in the game. ii) Assume you have defined a variable called myWeapon as follows: Gun myWeapon; myWeapon.model "Machine Gun"; myWeapon.size 80; Write a code fragment to reload all the gun bullets status to true. iii) Create a function called shot that takes in a reference parameter as Gun type. The function displays the message "Reload" if the first bullet is empty. Otherwise, for every single bullet, it displays "Bang" and set the last bullet to false.arrow_forwardA(n) _________ may be used to pass arguments to the constructors of elements in anobject array.arrow_forwardDrink Machine Simulator Write a program that simulates a soft drink machine. The program should use a structure that stores the following data: Drink Name Drink Cost Number of Drinks in Machine The program should create an array of five structures. The elements should be initialized with the following data: Drink Name Cost Number in Machine Cola .75 20 Root Beer .75 20 Lemon-Lime .75 20 Grape Soda .80 20 Cream Soda .80 20 Each time the program runs, it should enter a loop that performs the following steps: A list of drinks is displayed on the screen. The user should be allowed to either quit the program or pick a drink. If the user selects a drink, he or she will next enter the amount of money that is to be inserted into the drink machine. The program should display the amount of change that would be returned, and subtract one from the number of that drink left in the machine. If the user selects a drink that has sold out, a message…arrow_forward

Need a class which will contain: Student Name Student Id Student Grades (an array of 3 grades) A constructor that clears the student data (use -1 for unset grades) Get functions for items a, b, and c, average, and letter grade Set functions for items a, n, and c Note that the get and set functions for Student grades need an argument for the grade index. Need another class which will contain: An Array of Students (1 above) A count of number of students in use You need to create a menu interface that allows you to: Add new students Enter test grades Display all the students with their names, ids, test grades, average, and letter grade Exit the program Add comments and use proper indentation.

Create a struct called Booking that consists of a 3 digit flight number (e.g. 234), type of seat (E or B), the priceof a seat in economic class and the number of seats booked.Declare an array to store at least 30 Booking structs. 2. The user must be able to enter the information for a number of bookings from the keyboard. Ask whether abooking must be made (Y or N). If a booking must be made, a random 3 digit flight number must be generated.The user must be asked to enter the type of seat, the price per seat and the number of seats to book.Example of input:arrow_forward
- Write a statement that declares a class-level two-dimensional array named intOrders. The array should contain five rows and three columns.arrow_forwardFunction Description: Given a structure array with fields 'names', 'ASCI and 'points", return the name whose ASCII value is closest to its points (which is the coolest name). Notes: . There will never be a tie for the coolest name. . Do not compute the ASCII value of the names: it is given to you by the ASCII field. . Only the absolute value of the difference between ASCII value and points is considered. Hint: • You can index multiple char values from a structure using (struct.field) Examples: struct1= struct('names". ("Dwayne', 'Justin', "Peters), 'ASCI, (616, 637, 627). "points". (639, 651, 655)); ASCII 2 3 names Dwayne Justin' Peters coolestname = coolestName(struct1) coolestname "Justin' 616 637 627 points 639 651 655arrow_forward1.
