Enter a word as the argument for translate_into_pig_latin and the program will translate it into pig latin.
def translate_into_pig_latin(word1)
vowels = ["a","e","i","o","u"]
consonants = ["q","w","r","t","y","p","s","d","f","g","h","j","k","l","z","x","c","v","b","n","m"]
if vowels.include?(word1[0])
word1 << "ay"
else
if word1[0..1] == "qu"
word1[2..word1.length] << "qu" << "ay"
elsif consonants.include?(word1[0]) && consonants.include?(word1[1]) && consonants.include?(word1[2])
word1[3..word1.length] << word1[0..2] << "ay"

mfpiccolo / triangle.rb
Last active December 11, 2015 06:19
This program will take three numbers and tell you if it can be represented as a triangle and if so what kind of triangle.
def triangle(number1, number2, number3)
if number1 > number2 + number3 || number2 > number1 + number3 || number3 > number1 + number2
"This is not a triangle"
else
if number1 == number2 && number2 == number3
"You have got yourself an equalateral triangle. You should try and be more creative."
elsif number1 == number2 || number1 == number3 || number2 == number3
'This is an isosceles triangle. So you got that there going for you.'
elsif number1 != number2 && number2 != number3 && number3 != number1
'Oh snap! That is a scalene'

You can use the fibonacci method on positive integers an it will return the correlating fibonacci number.
class Integer
def fibonacci
if self < 0
"You can only use the fibonacci method with positive integers"
else
return self if (0..1).include? self
(self -1).fibonacci + (self - 2).fibonacci
end
end

@number = number
end
def roll
rand(1..@number)
