Code Snippets

Temperature Conversion

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

puts "Please enter degrees in Celcius:"
celcius = gets.chomp.to_f
	def convert(celcius)
  		return celcius * 9/5 + 32

puts "Enter a number:"
number = gets.chomp.to_i
def convert(number)
   return number % 10 
def convert100(number)
  return number % 100
if convert(number) == 1 && convert100(number) 
!= 11 && convert100(number) != 12 && 
convert100(number) != 13
  puts "That's the #{number}st item!"
elsif convert(number) == 2 && 
convert100(number) != 11 
&& convert100(number) != 12 && 
convert100(number) != 13
  puts"That's the #{number}nd item!"
elsif convert(number) == 3 && 
convert100(number) != 11 
&& convert100(number) != 12 && 
convert100(number) != 13
  puts "That's the #{number}rd item!"
  puts "That's the #{number}th item!"

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.


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

puts "How many digits would you like to see?"
digits ={|index| index +1}
def foo(number)
  return number % 3
def bar(number)
  return number % 5
digits.each do |number|
   if foo(number) == 0 && bar(number) == 0
    puts "Foobar"
  elsif foo(number) == 0
   puts "Foo"
  elsif bar(number) == 0
    puts "Bar"
    puts "#{number}"
