Write two seperate C# programs:

#:1

Create a program with a class that has one constructor to receive the information and three Value-Returning Method to return the results. The class will perform all the calculations. Class does not use any console commands (read and write).

The main will pass the input to the class and display the results. Void methods in main to display heading and instructions. After entering sales and sales increase percent (whole number not decimal), the program will calculate the amount of projected sales increase for each department and total sales increase

#:2

code an application that determines how many gallons of water is needed for a pool. Create Void Methods for the Header and Directions. Create 3 Value-Returning Methods that will return length, width, and height. Create another Value-Returning method that will accept 3 arguments (length, width, and height) and return the number of gallons needed. Use Math.Ceiling for the number of gallons. To calculate the gallons needed: 1 cubic foot of pool needs 7.5 gallons and declare as a constant.
