Boolean Logic Readings

1. Define a method, odd_integer?, that accepts an integer, n, as an argument. Your method should return true or false based on whether n is odd or even. Do not use the built in #odd? method. Instead, think about how you could use the modulo operator, %, to determine whether an integer is odd or even.

    def odd_integer?(n)
      n % 2 == 1
    end

2. Define a method, before_tarantula?, that accepts a string as an argument. The method should return true if the argument comes before the word "tarantula" alphabetically.

    def before_tarantula?(string)
      string < "tarantula"
    end

3. Fill out the following truth table:

4. Define a method, #same_type? that accepts any two objects as arguments. Your method should return true if both objects are the same type (String, Fixnum, etc.). Otherwise, return false.

    def same_type?(object1, object2)
      object1.class == object2.class
    end
