Class Photo Album C# Exercise - C# Programming Course

// Import the System namespace for basic functionality
using System;

// Define the PhotoAlbum class
public class PhotoAlbum
{
    // Declare a private integer field for the number of pages
    private int numberOfPages;

    // Define the default constructor to initialize with 16 pages
    public PhotoAlbum()
    {
        // Set numberOfPages to 16 by default
        numberOfPages = 16;
    }

    // Define an additional constructor to specify the number of pages
    public PhotoAlbum(int pages)
    {
        // Set numberOfPages to the specified value
        numberOfPages = pages;
    }

    // Define a public method to get the number of pages
    public int GetNumberOfPages()
    {
        // Return the current number of pages
        return numberOfPages;
    }
}

// Define the BigPhotoAlbum class, inheriting from PhotoAlbum
public class BigPhotoAlbum : PhotoAlbum
{
    // Define the constructor for BigPhotoAlbum with 64 pages
    public BigPhotoAlbum()
        : base(64) // Initialize the base class with 64 pages
    {
    }
}

// Define the test class to execute the program
public class AlbumTest
{
    // Main method to run the program
    public static void Main()
    {
        // Create a PhotoAlbum object with the default constructor
        PhotoAlbum defaultAlbum = new PhotoAlbum();
        // Display the number of pages for the default album
        Console.WriteLine("Default album pages: " + defaultAlbum.GetNumberOfPages());

        // Create a PhotoAlbum object with 24 pages
        PhotoAlbum customAlbum = new PhotoAlbum(24);
        // Display the number of pages for the custom album
        Console.WriteLine("Custom album pages: " + customAlbum.GetNumberOfPages());

        // Create a BigPhotoAlbum object
        BigPhotoAlbum bigAlbum = new BigPhotoAlbum();
        // Display the number of pages for the big album
