Finding # occurrences of a character in a string in Ruby

Question

I\'m looking for the Ruby method (1.9...) that can help me find the number of occurrences of a character in a string. I\'m looking for all occurrences, not just the first one.

Answer 1

This link from a question asked previously should help scanning a string in Ruby

scan returns all the occurrences of a string in a string as an array, so

"Melanie is a noob".scan(/a/)

will return

["a","a"]
