How can one write a function in ruby that takes a string and outputs the number of words contained in the string?

def WordCount(str)

  # code goes here
  return str 

end

# keep this function call here 
# to see how to enter arguments in Ruby scroll down   
WordCount(STDIN.gets)

Hi Chris!

Any time I'm asked to count words in a string, I usually break the string into an array and get the length of that. You can use the ruby #split method and pass in an empty space, like this "Testing string splitting".split(' '). Make sure you put a space between the quotes in the split method (otherwise it splits after every character). Then find the length of that array, and that should be the number of words in the string!

Hope that helps!
