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.

#prompt
puts "Enter degrees in Celsius:"
celsius=gets.to_f 

#method
def celsius_to_farenheit(c)
    c*1.8+32
end

#output
puts "That is #{celsius_to_farenheit(celsius)} degrees Farenheit."

#prompt
puts "Enter a number you want to make an ordinal:"
number = gets.to_i

#methods
def last_digit(number)
    number % 10
end

def last_two_digits(number)
    number % 100
end

def ordinateur(number)
    if last_two_digits(number) >= 11 && last_two_digits(number) <= 13
        return "th"
    
    elsif last_digit(number) == 1 
        return "st"
        
    elsif last_digit(number) == 2 
        return "nd"
        
    elsif last_digit(number) == 3 
        return "rd"
        
    else 
        return "th" 
        
    end
end

#output
puts "That's the #{number}#{ordinateur(number)} 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.

Foobar

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

#prompt
puts "How many items do you want to see?"
number_of_items = gets.to_i

#methods
def remainder_is_zero(dividend, divisor)
  if dividend % divisor == 0
    return true
  else 
    return false
  end
end

def foobar(number)
  foobar_array = []
  element_number = 1
  
  while element_number <= number    
    if remainder_is_zero(element_number, 3) && remainder_is_zero(element_number, 5)
      foobar_array << "foobar"     
    elsif remainder_is_zero(element_number, 3)
      foobar_array << "foo"      
    elsif remainder_is_zero(element_number, 5)
      foobar_array << "bar"    
    else 
      foobar_array << element_number
    end      
    element_number = element_number + 1    
  end
  
  puts foobar_array
end  

#output
puts foobar(number_of_items)
