Class Photo Album Learn programming C#

Lesson:

OOP Object Oriented Programming


Exercise:

Class Photo Album


Objetive:

Create a class "PhotoAlbum" with a private attribute "numberOfPages."

It should also have a public method "GetNumberOfPages", which will return the number of pages.

The default constructor will create an album with 16 pages. There will be an additional constructor, with which we can specify the number of pages we want in the album.

Create a class "BigPhotoAlbum" whose constructor will create an album with 64 pages.

Create a test class "AlbumTest" to create an album with its default constructor, one with 24 pages, a "BigPhotoAlbum" and show the number of pages that the three albums have.


Code:

using System;
namespace December_19th__b_
{
    class BigPhotoAlbum : PhotoAlbum
    {
        public BigPhotoAlbum()
        {
            numberOfPages = 64;
        }
    }
}

using System;
namespace December_19th__b_
{
    class AlbumTest
    {
        static void Main()
        {
            bool debug = false;

            //Create an album with its default constructor
            PhotoAlbum myAlbum1 = new PhotoAlbum();
            Console.WriteLine(myAlbum1.GetNumberOfPages());

            //Create an album with 24 pages
            PhotoAlbum myAlbum2 = new PhotoAlbum(24);
            Console.WriteLine(myAlbum2.GetNumberOfPages());

            //Create an BigPhotoAlbum 
            BigPhotoAlbum myBigPhotoAlbum1 = new BigPhotoAlbum();
            Console.WriteLine(myBigPhotoAlbum1.GetNumberOfPages());

            if (debug)
                Console.ReadLine();
        }
    }
}
