        attr_reader :title, :author
        @@total_books = 0
        def self.total_books
          @@total_books
        end
        def initialize(title, author)
          @title = title
          @author = author
          @@total_books += 1
        end
      end
      class Library
        attr_reader :books
       
        def initialize
          @books = []

        def add_book(book)
          @books << book
        end
        def total_books_in_library
          @books.size
        end
      end
      library = Library.new
      library.add_book(Book.new("1984", "George Orwell"))
      library.add_book(Book.new("To Kill a Mockingbird", "Harper Lee"))
      result1 = Library.total_books
      result2 = library.total_books_in_library
      What will be the values of result1 and result2, respectively?

      Answer: C
  • Question 2

    • In Ruby, understanding non-local exits such as break, next, and return within the context of blocks and methods is crucial for controlling the flow of a program. Consider the following Ruby code snippet:

      def test_method [1, 2, 3].each do |i| return i if i == 2 end "No match"end result = test_method Based on this code, which two of the following statements are true regarding non-local exits in Ruby?

      Answer: A,E
  • Question 3

    • In Ruby, the understanding of operators and their precedence is crucial for writing correct and efficient code. Consider the following Ruby code snippet:

      a = 10b = 3result1 = a + b * 2result2 = (a + b) % 3result3 = a ** b / 2 Based on this code, which two of the following statements are true regarding the use of operators and their precedence?

      Answer: A,E
  • Question 4

    • Evaluate the following Ruby code snippet that involves the forwardable and date modules:
