Question

    Create a C# program named PaintingDemo that instantiates an array of eight Room objects and demonstrates the Room methods. The Room constructor requires parameters for length, width, and height fields; use a variety of values when constructing the objects. The Room class also contains a field for wall area of the Room and number of gallons of paint needed to paint the room. Both of these values are computed by calling private methods. Include read-only properties to get a Room’s values. A room is assumed to have four walls, and you do not need to allow for windows and doors, and you do not need to allow for painting the ceiling. A room requires one gallon of paint for every 350 square feet (plus an extra gallon for any square feet greater than 350). In other words, a 12 x 3 x 10 room with 9-foot ceilings has 396 square feet of wall space, and so requires two gallons of paint.

Answer 1

Output will be like:

Code will be like:

using System;

namespace PaintingDemo
{
class Program
{
static void Main(string[] args)
{
Room obj1 = new Room(5, 7, 20);
Room obj2 = new Room(2, 7, 20);
Room obj3 = new Room(3, 7, 20);
Room obj4 = new Room(4, 7, 20);
Room obj5 = new Room(7, 7, 20);
Room obj6 = new Room(8, 7, 20);
Room obj7 = new Room(9, 7, 20);
Room obj8 = new Room(10, 7, 20);

Console.ReadLine();
}
}
class Room
{
public int length;
public int width;
public int height;

public Room(int len, int width,int heigh)
{
this.length=len;
this.width=width;
this.height=heigh;

wallArea();
Console.WriteLine("Number of gallons of paint needed are "+gallonsOfpaint());

}

private double wallArea()
{
return length * width * height;
}

private double gallonsOfpaint()
{

double paintCount = wallArea()/350;

  
return Math.Ceiling(paintCount);
}
}
}
