Class Photo Album - C# Programming Exercise

Write a C# class called "PhotoAlbum" with a private attribute "numberOfPages". The class should also have a public method named "GetNumberOfPages", which will return the number of pages. The default constructor will create an album with 16 pages. There will be an additional constructor where we can specify the number of pages we want in the album. Then, create a class called "BigPhotoAlbum" whose constructor will create an album with 64 pages. Finally, create a test class called "AlbumTest" that will create an album using the default constructor, one with 24 pages, a "BigPhotoAlbum", and display the number of pages each of the three albums has.

Class Photo Album

Objective

Write a C# 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.
