ruby , Ruby access words in string


Ruby access words in string

Question:

Tag: ruby

I don't understand the best method to access a certain word by it's number in a string.

I tried using [] to access a word but instead it returns letter.

puts s 
# => I went for a walk
puts s[3]
# => w

Answer:

What you are doing will access the fourth character of String s.

Split the string to an array and then access the fourth element as follows.

puts s.split[3]

Note: Calling split without parameters separates the string by whitespace.

Edit: Fixing indexes. The index starts from 0. That means s.split[3] will access fourth element.
