Question

Create a program named TilingDemo that instantiates an array of 10 Room objects and demonstrates its methods. The Room constructor requires parameters for length and width fields; use a variety of values when constructing the objects. The Room class also contains a field for floor area of the Room and number of boxes of tile needed to tile the room. Both of these values are computed by calling private methods. A room requires one box of tile for every 12 full square feet plus a box for any partial square footage over 12, plus one extra box for waste from irregular cuts. In other words, a 122 square foot room requires 12 boxes—10 boxes for the first 120 square feet, 1 box for the 2 extra square feet over 120, and 1 box for waste. Include read-only properties to get a Room’s values."

The solution should be a console application in C#. Thank you.

Answer 1

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);
}
}
}

Answer 2

//the above screenshot only shows the first 5 rooms out of 10

using System;

namespace TilingDemo
{
    class MainClass
    {
        public static void Main (string[] args)
        {
            //initialises an array of rooms
            Room[] rooms = new Room[10];
            Random r = new Random ();

            //iterates over the array
            for (int i = 0; i < 10; i++)
            {    
                //initialises rooms with random integer vaule <100
                rooms [i] = new Room (r.Next (100),r.Next(100));
            
            }

            //iterates over the array and prints all the instatcfes
            for (int i = 0; i < 10; i++) {

                Console.WriteLine ("\nRoom" + i);
                Console.WriteLine (rooms [i].ToString() );
            }
        }
    }

    class Room
    {
        int length;
        int width;
        int area;
        int boxoftiles;

        //the required constructor
        public Room(int length, int width)
        {
            this.length = length;
            this.width = width;
            this.area = calculateArea();
            this.boxoftiles = calculateBoxes ();
        }
                        
        override public String ToString()
        {
            String str="length: "+this.length;
            str = str + "\nwidth: " + this.width;
            str = str + "\narea: " + this.area;
            str = str + "\nBOxes required: " + this.boxoftiles;
            return str;

        }


        int getArea(){
            return this.area;
        }
        int getBoxes()
        {
            return this.boxoftiles;
        }

        //returns the area by simply multipling width to length
        private int calculateArea()
        {
            return this.width* this.length;
        }

        //calcultes the number of boxes required
        private int calculateBoxes()
        {
            int boxes = this.area / 12;
            //if the area is divisible by 12 then return the number of boxes
            if (this.area%12 == 0) {
                return boxes;
            
            } else {
                //if not divisible add 1
                return boxes + 1;
            }
        }

    }
