Question

in c#:

Create a class named Square that contains fields for area and the length of a side and whose constructor requires a parameter for the length of one side of a Square. The constructor assigns its parameter to the length of the Square’s side field and calls a private method that computes the area field. Also include read-only properties to get a Square’s side and area. Create a class named DemoSquares that instantiates an array of ten Square objects with sides that have values of 1 through 10. Display the values for each Square. Save the class as DemoSquares.cs

PLEASE SHOW THE OUTPUT.

Answer 1

checking with array size of 5 you can change it to what ever you like

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

namespace DemoSquares

{

class Square

{

public int length;

public int area;

public Square() // constructor

{

Length = 1; //intializing to 1 because its from 1 to 10

}

public int Length // length getter and setter

{

get

{

return length;

}

set

{

length = value;

findArea();

}

}

public int Area

{

get

{

return area;

}

}

private void findArea()

{

area = length * length; // calculate area

}

}

public class DemoSquares

{

public static void Main()

{

Square[] sqr = new Square[5];

int i;

for (i = 0; i < sqr.Length; ++i)

sqr[i] = new Square();

sqr[1].Length = 2;

sqr[2].Length = 3;

sqr[3].Length = 4;

sqr[4].Length = 5;

Console.WriteLine();

Console.WriteLine(" Square 1 length is {0}, and area is {1}", sqr[0].length, sqr[0].area);

Console.WriteLine();

Console.WriteLine();

Console.WriteLine(" Square 2 length is {0},and area is {1}", sqr[1].length, sqr[1].area);

Console.WriteLine();

Console.WriteLine();

Console.WriteLine(" Square 3 length is {0}, and area is {1}", sqr[2].length, sqr[2].area);

Console.WriteLine();

Console.WriteLine();

Console.WriteLine(" Square 4 length is {0}, and area is {1}", sqr[3].length, sqr[3].area);

Console.WriteLine();

Console.WriteLine();

Console.WriteLine(" Square 5 length is {0},and area is {1}", sqr[4].length, sqr[4].area);

Console.ReadLine();

}

}

}
