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

I was able to solve this by passing a string through scan as shown in another answer.

For example:

string = 'This is an example'
puts string.count('e')

Outputs:

2

I was also able to pull the occurrences by using scan and passing a sting through instead of regex which varies slightly from another answer but was helpful in order to avoid regex.

string = 'This is an example'
puts string.scan('e')

Outputs:

['e','e']

I explored these methods further in a small video guide I created after I figured it out.
