GetMonth - This method prompts for and returns the month GetNumMurals - This method prompts for and returns the number of murals scheduled and is called twice -- once for interior murals and once for exterior murals ComputeRevenue - This method accepts the number of interior and exterior murals scheduled, accepts the month they are scheduled, displays the interior and exterior prices, and then returns the total expected revenue DataEntry - This method fills an array with customer names and mural codes and is called twice -- once to fill the array of interior murals and once to fill the array of exterior murals GetSelectedMurals - This method continuously prompts for mural codes and displays jobs of the corresponding type until a sentinel value is entered. In order to prepend the $ to currency values, the program will need to use the CultureInfo.GetCultureInfo method.
in C#
A positive integer greater than 1 is said to be prime if it has no divisors other than 1 and itself. Write a program that asks the user to input an integer greater than 1, then display all of the prime numbers that less than or equal to the number entered. The program should work as follows:
• Once the user has entered a number, the program should display an array with all of the integers from 2 up through the value entered.
• The program should then use a loop to step through the array. The loop should pass each element to a method that displays the element whether it is prime number.
Your result should look like, for example:
Enter an integer greater than 1: 9
2, 3, 4, 5, 6, 7, 8, 9
2 is prime
3 is prime
4 is not prime
5 is prime
6 is not prime
7 is prime
8 is not prime
9 is not prime

In this project you will generate a poker hand containing five cards randomly selected from a deck of cards. The names of the cards are stored in a text string will be converted into an array. The array will be randomly sorted to "shuffle" the deck. Each time the user clicks a Deal button, the last five cards of the array will be removed, reducing the size of the deck size. When the size of the deck drops to zero, a new randomly sorted deck will be generated. A preview of the completed project with a randomly generated hand is shown in Figure 7-50.

- 2. Rotate Left k cells Use Python Consider an array named source. Write a method/function named rotateLeft( source, k) that rotates all the elements of the source array to the left by 'k' positions. You must execute the method by passing an array and number of cells to be shifted. After calling the method, print the array to show whether the elements have been shifted properly. Example: source=[10,20,30,40,50,60] rotateLeft(source,3) After calling rotateLeft(source,3), printing the array should give the output as: [ 40, 50, 60, 10, 20, 30]arrow_forwardJumping in the Mega Millions fever, your lab is to write a program that simulates the Mega Millions lottery draw. Your program must have an array of five integers named winningNumbers, with a randomly generated number in the range of 0 through 9 for each element in the array. Your program should ask the user to enter five numbers and should store them in a second integer array named player. The program must compare the corresponding elements in the two arrays and count how many numbers match. For example, the following shows the winningNumbers array and the Player array with sample numbers stored in each. There are two matching elements, elements 2 and 4. Once the user has entered a set of numbers, the program should display the winning numbers and the player's numbers and tell how many numbers matched.

Radio buttons should allow the choice between First Class and Economy. The app should then assign a seat in the first-class section (seats 1–5) or the economy section (seats 6–10). Use a one-dimensional array of type bool to represent the seating chart of the plane. Initialize all the elements of the array to false to indicate that all the seats are empty. As each seat is assigned, set the corresponding element of the array to true to indicate that the seat is no longer available. Your app should never assign a seat that has already been assigned. When the economy section is full, your app should ask the person if it is acceptable to be placed in the first-class section (and vice versa). If yes, make the appropriate seat assignment. If no, display the message “Next flight leaves in 3 hours."arrow_forward
- An array called number contains 20 integer values and must be filled with values in the following way: Fill the array with consecutive even numbers starting from 10. Start again at the first element and increase every fourth element with 3. Replace the value of the first four elements each with its square. Deduct 2 from the last 3 elements. Swap the value of element 5 and element 15. Add the value of the first element to that of the last element Add consecutive integers (starting from 1) to all even elements.Remember, the first element has a subscript of 0 and the last element (element 20) has a subscript of 19.The following must be displayed: All elements must be displayed each on a new line.

In this exercise, you will use this knowledge to create an interactive game where players attempt to move through a maze. You will start by creating a pre-defined 2D array with the following values: :-, X","X"} "X","W"} "X","_"} "} 'X","X"} {"_" " "y" " " You will then set the player (represented by "O") at index 0, 0 of the array, the top-left corner of the maze. You will use a loop to repeatedly prompt the user to enter a direction ("Left", “Right", “Up", or “Down"). Based on these directions, you will try to move the player. If the location is valid (represented by “_"), you will move the player there If the location is out of bounds (e.g. index 0, -1) or the command is invalid, you will inform the player and prompt them to enter another direction If the location is a wall (represented by “X"), you will tell the user they hit a wall and the game is over.

You need to create a new array which holds the averages of these two tests. You may assume that the first element of the first test array refers to the student who also has the grade in the first element of the second test, and the last element in each array are the grades the last student earned for each test. All students received grades for both tests, meaning both test arrays are of the same length. Complete the method, named makeAverage, in the class named Grades.java. There are two parameters to this method: the first is the integer array representing the grades of the first test, and the second is the array containing the grades of the second test. The new average array should be returned by the method. The grades should be treated as double variables. For example, consider the test grades for the five students in the following arrays: [ 87 ] [ 91 ] [ 76 ] [ 76 ] [ 94 ]…arrow_forward
