The figures should be stored in a two-dimensional array. Once the figures are entered, the program should display the following data for each quarter: • A list of the sales figures by division • Each division's increase or decrease from the previous quarter (this will not be dis- played for the first quarter) The total sales for the quarter • The company's increase or decrease from the previous quarter (this will not be dis- played for the first quarter) • The average sales for all divisions that quarter • The division with the highest sales for that quarter Input Validation: Do not accept negative numbers for sales figures.arrow_forward
- Find primes This program creates and displays a 5x10 matrix(5 rows and 10 columns) of random integers between 1 and a maximum value(user input). Hint: Use the random library to generate each number and place it into your 2D list. The program then counts the number of prime numbers in each row of the array and displays this number, along with the found primes. The program finally displays the total number of prime numbers in the matrix.arrow_forwardTrue or False. A simple variable, also called a scalar variable, is one that is unrelated to any other variable in the computer’s internal memory. The bubble sort algorithm gets its name from the fact that as the larger values drop to the bottom of the array, the smaller values rise, like bubbles, to the top. Programmers use arrays to temporarily store related data in the internal memory of the computer. Different variables in the same array may have different data types. The elements in an array can be used just like any other variables. When an array is sorted in ascending order, the first element contains the largest value and the last element contains the smallest value. When passing an array by reference in C++, you do not include the address-of operator before the formal parameter’s name in the function header. You distinguish one variable in a one-dimensional array from another variable in the same array using a unique integer,…arrow_forwardComprog Any loop statement can be used to traverse an array.arrow_forward
- Programming: 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_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.

- JAVA CODE PLEASE Functions with 2D Arrays Quiz by CodeChum Admin Write a program that asks the user for the row and column size of a 2D array and asks the user for the elements. Write the total of the sum of each row multiplied with the row number. Example: 1 2 3 -> (1+2+3) * 1 = 6 4 5 6 -> (4+5+6) * 2 = 30 7 8 9 -> (7+8+9) * 3 = 72 total: 108 Input 1.

Lottery Number Generator Design a program that generates a 7-digit lottery number. The program should have an Integer array with 7 elements. Write a loop that steps through the array, ran- domly generating a number in the range of 0 through 9 for each element. (Use the random function that was discussed in Chapter 6.) Then write another loop that displays the contents of the array.arrow_forwardPart 1 & 2) Lottery Winners Write a program that initializes an array with ten numbers (given below). Then let the player enter his or her lottery number. The program should ask the user if he/she wants to perform a linear search or binary search. (If the user chooses binary search, using one of the sorting algorithms we learned in the class, sort the array). Based on the searching algorithm payer chooses, it should print out the number of searching comparisons performed and if it was a winning number. int ticket[] = {85647, 62483, 13579, 26792, 52551, 33445, 79422, 76172, 93121, 26791 };\ Microsoft Visual Studio Debug Console Enter your 5-digit lottery number: 12345 Press 1 to perform linear search, 2 for binary search: 1 Original values: 85647 62483 13579 26792 52551 33445 79422 76172 93121 26791 Number of comparisons made: 10 You did not win.
