For all vowels in a string, I'm trying to print the amount of the vowels. If I push every instance of a vowel to a new array, then the length of the array + 1 would be the answer. I don't know if my push is failing. Any help would be appreciated.
def count_vowels(string)
arr = ['a', 'e', 'i', 'o', 'u']
letters = string.split("")
letters.each do |x|
if x == arr.any?
vowels = vowels.push(x)
print vowels.length
else
print 0
end
end
Once you get more familiar with Ruby, you'll realize there are much more useful methods than "each" for things you're trying to accomplish, like counting the vowels in a string. Like for example:
my_string = 'Hey there'
def how_many_vowels_has(this_string)
this_string.scan(/[aeiou]/).size
end
p how_many_vowels_has(my_string) #=> 3
or you can call String#count on the string itself:
my_string = 'Hey there'
p my_string.count('aeiou') #=> 3
From what I can see, you need to spend more time learning about how Enumerable works, scope and the fact that everything in Ruby is an object. Also, solving problems the "Ruby" way, using the constructs the language provides you.
this_string.count('aeiou') #=> 3
this_string.downcase.count('aeiou') or this_string.count('AaEeIiOoUu'). My bad.
The problem is with arr.any? it does not do what you think it does.
According to the documentations:
Passes each element of the collection to the given block. The method returns true if the block ever returns a value other than false or nil
Instead, you want to use if arr.include? x
