Workshop 4

1. Create, test and debug a Ruby program called dognames.rb or catnames.rb to accept 3 names from the keyboard and to display each name on the screen in alphabetical order WITHOUT using a data structure such as a list.

This is my first Ruby program dognames.rb. I use Ruby interpreter (irb.bat) for test and debug the Ruby program. And then run the program from the console window using either C:\ruby dogname.rb.

def dognames

  puts "Whats your dog name: "

  $dog1 = gets

  puts "Whats your dog name: "

  $dog2 = gets

  puts "Whats your dog name: "

  $dog3 = gets

array = [$dog1,$dog2,$dog3]
puts "your dog name"
puts array.sort

dognames

2. Write a Ruby program called fizzbuzz.rb that prints the numbers from 1 to 100. But for multiples of three print “Fizz” instead of the number and for the multiples of five print “Buzz“. For numbers which are multiples of both three and five print “FizzBuzz“.

This is my Fizzbuzz program fizzbuzz.rb.

def FizzBuzz

  1.upto(100) do |i|

    if i % 5 == 0 and i % 3 == 0

      puts "FizzBuzz"

    elsif i % 5 == 0

      puts "Buzz"

    elsif i % 3 == 0

      puts "Fizz"

    else

      puts i

    end

  end

end

fizzbuzz
