Array of structures:
In C++, it is possible to create an array of structure. It is used to store a group of records contains multiple data members of various data type. A single array of structure can replace many arrays of regular type variable.
- Array of structures can be defined like normal array.
The structure array is declared through the following format:
struct_name variable[size];
Consider the following array definition:
//Declaration of structure array
Car values[5];
- In the above example, “Car” represents the structure type of the array, “values[]” is the array name, and the number inside the brackets is the size declaratory of the array.
Subscript of an array:
In C++, array elements can be accessed using a subscript. In an array, each element assigned with the unique number, which is specified inside the brackets, is referred to as a subscript.
- By default, structure members are defined as public. Hence structure members can be accessed by place the dot operator (.) and member name after the array subscript.
Example:
//Assign the value for model member of values[2].
values[2].model= "New"
- In above statement, the value “New” is assigned in the third element ofthe values array for model member.

- You can copy all elements of one array into one another with an assignment statement. True or Falsearrow_forwardCASE STUDY#:Grade Register Write a grade register program to keep and process the grades of students. The program contain a class called GradeRegister. This class has two data members known as CourseName and an array of integer called Grades. The array Grades keep the grades of students of the same course. GradeRegister class have three methods as GetHighestGrade(), GetLowestGrade() and GetAverageGrade().The method GetHighestGrade return the maximum grade as integer from the array Grades and GetLowestGrade return the minimum grade value as integer from the array Grades. The GetAverageGrade method will return the average of grades from Grades array as float value. The parameterized constructor inside GradeRegister class will take two parameters to initialize the two data members of same class as mentioned before. Write a driver class GradeRegisterDriver to declare and initialize an integer array for grades and pass through the GradeRegister class constructor along with the course name.…arrow_forwardLotto Program C++Write a program that simulates the Powerball lottery. In Powerball, a ticket is comprised of 5 numbers between 1 and 69 that must be unique, and a Powerball number between 1 and 26. The Powerball does not have to be unique. Hint: You can use an array to represent the 5 unique numbers between 1 and 69, and an integer variable to represent the powerball. The program asks the player if they'd like to select numbers or do a 'quickpick', where the numbers are randomly generated for them. If they opt to select numbers, prompt them to type the numbers in and validate that they are unique (except the powerball), and in the correct range. The program then generates a 'drawing' of 5 unique numbers and a Powerball, and checks it against the user's lotto ticket. It assigns winnings accordingly. Because it is so rare to win the lottery, I suggest hard coding or printing values to when testing the part of the program that assigns winnings.arrow_forward
- When you create a array of a class type, with what value will each element of the array be initialized?arrow_forwardQUESTIONS- 1. Create and array of objects named movies . Each of the objects in the array will represent a movie.Each object should have properties for:movie titlerelease yearrating (your rating 1 - 10)genres (an array of genres. eg ["Drama", "Mystery", "Sci-Fi", "Western"] )The array should contain at least 5 of movies you have seen (choose your own movies)You do not need to use JSON to create this arrayYou can use IMDB if you need help finding the info for your movie2. Now that digital format is taking over, we would like to add a property to each object for the format (“film” or“digital”). The property will be called format . Assuming that all movies in our data set where shot on film, use.forEach() to add the property and set a value of “film” for each movie.3. Use the .map() method to create an array of movie titles from our initial data set named movieTitles .4. Use the .reduce() method to find the highest and lowest rated movies in the data set. Store these objects invariables…arrow_forwardProgramming: Multi-Array Assignment Instructions Overview Using a two-dimensional array, you will create the game battleship using a text file that contains the board. The user will enter coordinates to try and find ships and sink them. Instructions Imagine you are using a two-dimensional array as the basis for creating the game battleship. 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…arrow_forward

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

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…arrow_forward(Electrical eng.) Write a program that declares three one-dimensional arrays named volts, current, and resistance. Each array should be declared in main() and be capable of holding 10 double-precision numbers. The numbers to store in current are 10.62, 14.89, 13.21, 16.55, 18.62, 9.47, 6.58, 18.32, 12.15, and 3.98. The numbers to store in resistance are 4, 8.5, 6, 7.35, 9, 15.3, 3, 5.4, 2.9, and 4.8. Your program should pass these three arrays to a function named calc_volts(), which should calculate elements in the volts array as the product of the corresponding elements in the current and resistance arrays (for example ,volts[1]=current[1]resistance[1]). After calc_volts() has passed values to the volts array, the values in the array should be displayed from inside main().arrow_forward
