Code Snippets

Temperature Conversion

This Ruby program will prompt the user for a temperature in degrees Celsius and let the user know what the corresponding temperature is in Fahrenheit.

 puts "Enter degress in Celcius:"
      celcius = gets.chomp

      fahrenheit = (celcius.to_i * 9/5)+32

      conversion = "The temperature is #{fahrenheit} degrees Fahrenheit."
      puts conversion 

Ordinal Challenge

This Ruby program will convert a plain number to the ordinal of the number. So for example, if the user enters 2, it will display 2nd, if the user enters 3, it will display 3rd, etc.

puts "Enter a number:"
      n = gets.chomp.to_i 
      if (11..13).include?(n % 100)
     puts "That's the " + n.to_s + "th item!"
        case n % 10
            when 1
              puts "That's the " + n.to_s + "st item!"
            when 2
              puts "That's the " + n.to_s + "nd item!"
            when 3
              puts "That's the " + n.to_s + "rd item!"
            suffix = "th"  
            puts "That's the " + n.to_s + suffix + " item!"


This Ruby program is an adaptation of a classic technical interview problem which displays sequences of the Foobar pattern.

puts "How many items do you want to see?"
items = gets.chomp.to_i

number = []
(1..items).each do |n|
    if n % 3 == 0 && n % 5 == 0
        number << "foobar"
    elsif n % 3 == 0
        number << "foo"
    elsif n % 5 == 0
        number << "bar"
        number << n

puts number
