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.


def celsiusToFahrenheit(c)
    return c * 9/5 + 32
end
puts "Please enter a celsius temperature and I will convert it to farenheit. "
c = gets.to_f
f = celsiusToFahrenheit(c)
puts "The correct fahrenheit temperature for #{c} is #{f}"

puts "Please enter a number."
num = gets.chomp.to_i

def set_ordinal(num)
    
right_digit = num % 10
    if num >= 11 && num <= 13
        puts "That's the #{num}th item."
    elsif right_digit == 1
        puts "That's the #{num}st item."
    elsif right_digit == 2
        puts "That's the #{num}nd item."
    elsif right_digit == 3
        puts "That's the #{num}rd item."
    else puts "That's the #{num}th item."
    end
    
end

set_ordinal(num)

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.

def play_foobar(entry)
i = 1
while i <= entry
    if i >= 3 && i % 3 == 0 && i % 5 == 0
        puts ("foobar")
    elsif i >= 3 && i % 3 == 0
        puts ("foo")
    elsif i >= 3 && i % 5 == 0
        puts ("bar")
    else
        puts(i)
    end
i += 1
end
end

puts ("What number do you want to start the game foobar with?")
entry = gets.chomp.to_i
play_foobar(entry)

class Image

  # Here is my initializer. It is formatted per the spec from Coding Boot Camp that the array should be made from 4 arrays
  # or a two-dimensional array.
  def initialize(arr)
    @image = arr
  end

  def output_image
    @image.each do |x|
      x.each do |cell|
        print cell
                # This looks down from the rows
                if i < @length - 1
                  if @image[i+1][j] == 0
                    @image[i+1][j] = 2
                  end
                end

                # This looks up from the rows
                if i > 0 && @image[i-1][j] == 0
                  @image[i-1][j] = 2 
                end

                # This looks to the right until it gets to the end.
                if @image[i][j+1] == 0
                  @image[i][j+1] = 2
                end

              # This looks to te left. I tried to set this so it will never look over the side of the array.
              # I'm afraid of what might happen if my program does that too muc.
                if j > 0 && @image[i][j - 1] == 0
                  @image[i][j - 1] = 2
                end
end

Image Blur

This program takes an input to say how far to blur from the points in the matrix that begin with a 1 in them. The array can be 4 items tall, but any width.
